RE: Amiga monitor on MSX
Look at following diagram: (I have a SCART connector on it, but you should be able to connect it to a Turbo R) So all the fuzz about seperate syncs is out of the way now: the monitor has a seperate composite Synchrinisation input! A-ha. Now it's clear: according to your wiring diagram, the newer 1084 models with DB-9 connector seem to HAVE a composite sync input on pin 7. Building a custom SCART or DIN-8 cable to hook an MSX to them would be straightforward. But the problem is with older models which have a DIN-6 connector for analog RGB with no comp. sync but separate h/v syncs. They have a separate DIN-8 connector for digital RGB which HAS a comp. sync input BUT the analog/ TTL switch prevents that signal from feeding the sync circuitry when working in analog mode 8:( The best solution would be soldering a female SCART socket onto the empty space reserved for that purpose, but a bridge on the place and my suspicions that some components apart from the socket are missing discouraged my purpose. By the way, are these monitors better than Philips CM-8833? The older model is EXACTLY the same monitor but in white color. The newer model is more robust, with smoother design, has a monochrome green switch, includes the dreaded COMPOSITE SYNC pin 8:) and was electronically revised and enhanced to support the heavier duty they got from Amiga users 8:D Kiss you all.

Re: DiskROM *MOTOR OFF*
Well, I can tell you that it's pretty irritating if the harddisk spins down! Several demo's do that also, e.g. the demo Scrollmania (I thought it was) in IOD's Metal Limit. Other software does so too... BUt ok, in your game it isn't that much of a problem, since indeed, it doesn't have to load afterwards (does it? Don't you need to load the next stage pictures?) AND you cannot quit the game other than reset the MSX. Gee... the game loads the girly backdrop *every* stage. I guess you haven't completed the 1st round yet! 8:D You still can quit the game in this release. Press CLR/HOME. The problem if my harddisk stops, is that I can't turn it on again! Only by turning off the power of the powersupply, wait 3 seconds, and turn it on again... ?!?!?! Is that a standard behaviour of harddisks on the MSX?!? If so, I think the best solution would be: To play the game from diskette, boot the computer (the final release will have a custom bootsector and *no* MSX-DOS system files). The game system will stop the motor via the *INTERFACE SPECIFIC STOP ROUTINE* (please confirm address and parameters if any). If ran from other media booted with an already installed MSX-DOS, the game system won't stop anything. Nice or what? MARK 2 MSX Mailinglist.

Re: DiskROM *MOTOR OFF*
I don't know if this works with all kinds of disk-interfaces, but I'm used to do the following: LD IX,04029H LD IY,(0F347H) CALL 0001CH This calls the STOPDRV routine from diskrom (entry point 4029h). But I don't know what will happen if you have 2 disk-interfaces connected to one MSX. Does somebody know? OK, thanks. Now I'm calling the STOPDRV routine for each valid DiskROM found in the table at #FB21. It works very smooth. Perhaps it will spin down hard disks and similar devices but that's OK since the game gathers all system resources and no scatter disk access is done during gameplay. MARK 2 MSX Mailinglist.

Re: Snes vs Megadrive rectification
Yeah. So what was the point of that "CPU immense power" then??? Well, Some MegaDrive (Genesis) games try to do with 68000 the same as SNES does with its VDP: rotation, scalling, etc, etc, etc. A fast main processor can be used to do some calculation... I think that is the point... Not only Video calculation, but any calculation that is needed... You have to agree that the "main loop" of a game isn't a very time-consuming process, when you do not consider video drawing, music play, etc, etc, etc... And fast processor means nothing if not used wisely. Yeah, but a 7MHz 68000 is *NOT* a fast processor, whatever use you make of it! Even with 2 68000 processors, Z80, VDP, CDROM, etc, etc, etc, SegaCD lost the war agains SNES... Just because SNES has a better VDP and effects processor built-in... That's it. It lost the war because even 2 68000s cannot emulate in software what a VDP does in hardware, at a reasonable speed. I'd like to point out an Atari ST had serious problems to move a single 16 color layer. And I don't mean SMOOTH moving! A dedicated device yields much higher throughtput than a general purpose CPU.

Re: Snes vs Megadrive rectification
Please get your facts straight Laurens. The MegaDrive/Genesis had a 68000 processor running at 7 mhz. Twice the speed of the SNES. I admit that the Snes has cool graphical features like you mentioned, but take one look at the sonic games released for the Genesis, it has so many layers most computers can't emulate it, because of the immense speed!

Re: C64 cartridge for MSX. :)
Is that possible? How about SID? :) SID is the sound chip, not? It looks like a PSG (3 channel, noise, etc...), peharps can be simulated using PSG. No way. And how to do 6502 emulation? Classical emulation or a simulation (like Executor)? 6510 emulation is feasible. But the 1MHz CPU is a mere register setup device for the custom chips, like on the Amiga. Ok, I don't know C64 but comparing C64 with Turbo-R: Well, C64 has poor sound and no much fine performance.

Re: C64 cartridge for MSX. :)
Which are the special things of SID? Great effects? SID has really powerful programmable filters, complex interchannel modulations (including ring) and different oscillator waveforms (including variable width pulses) which yield a rich, dynamic sound. Its design is sheer brilliant. Hence the Byte award. Bear in mind it was designed in the VERY EARLY 80s, so comparing it against a TR or whatever 90s computer has little sense. C64 is the computer with the best built-in sound capabilities of ITS AGE. About C64, I were 6 years old the last time I played with one, and then, it seemed wonderful to me. Recently I downloaded the C64 emu for PC, and also one game, "HERO" (which was the first game I ever played on a computer). And the MSX version is much better than the C64 version... perhaps the HERO conversion to C64 wasn't good, I don't know... Hero for C64 sucks big time. MARK 2 MSX Mailinglist.

Re: Compass improvement??? Jon! Listen!
Yeah! Let's for example tokenize CALL as #CD, RET as #C9 etc... Well yes, that was the idea. Would assemble really fast, wouldn't it? And if use #FF as opcode for other things like labels or comments... (#FF #FF = RST #38). #21 #00 #00 would then be LD HL,# in the code and #21 #FF "LABEL1" would be LD HL,LABEL1. Gee... again, this already exists and it's called OBJECT CODE! 8:D But the great thing is... that it's indeed a great idea and it would work!

Re: Text editor w/ varitabs
I'm not sure what I'm looking at is the same you typed. You used TABs in this e-mail and my reader may have a different tab width than yours. This is what I see (I replaced tabs by spaces): It's not the same, so I'll drop tabs further on for assembler. The format I use: FOOBAR LD A,B DJNZ FOORBAR Never label and code on a single line. It's practical when inserting a line, removing a line or cutting/pasting lines. Nice to see everyone has its own definite style. Personally I'm pretty demanding and always work with an editor capable of dealing with labels + code on a single line in a comfortable way (like the fab DevPac editors for ST Amiga). For me the air in the sources is the most important issue when it comes to readibility, and I find separate labels a bit confusing. As the most edited labelled lines are the first of the subroutines, I usually use separate labels just this way: FOOBAR ; USELESS ENDLESS LOOP ; E: FOO FOO FOO FOO ; M: BAR BAR BAR BAR LD A,(FOO_VAR) USELESS NOP DEC A JR NZ,USELESS RET I'm practical, but visually appealing 8:) By the way, MS Word can do variable tabs, but I don't think it qualifies as a good text editor... ;) Definitely not 8:) MARK 2 MSX Mailinglist.

No, it saves some time... :) It saves a CALL and a RET-instruction. Mmm... if it wasn't for the unjustified JP (and your smiley!)

Well, it should be, since this is the first computer I still had not the need to disassemble / reverse-engineer its ROM!!! 8:) But if you really want to know why they used JP: let's just say that JP is generally faster than JR, and you will never get 'out of range'-problems, so most programmers use JP all the time. I do too. I hardly use JR-instructions. Only sometimes, when it's faster than JPs (for example in conditional jumps which are 'false' more than 60% of the times they are executed). The best solution is an assembler with optimization capabilities. Again, like DevPac for ST Amiga.

Re: Meaning of VRAM size speed bits
1SP? Sprite (0=On, 1=Off)
The name is SPD, not SP. With it you can disable the sprites, which
drastically spees up the VDP (that's why the name is SPeeD).
Mmm... I'm thinking in disabling sprites + display in the invisible parts
of the screen in my overscan routine to gain some speed (dunno if that
would actually mess/disturb/desync display).
Anyway with the game code 90% complete the main CPU VDP loop only takes
1/4 of the frame time!!! -_-v
2VR0 VRAM size and speed
It's the VRAM mode.
According to my docs it has to be 0 (it has no value), but when looking to
the meaning of the 3rd bit I think you can switch between 1 and 4-bit VRAM
with this. On MSX always keep it 0!!!
OK. I prefer to poke values directly to VDP registers instead of reading
the shadow, mask and modify the bits I want provided I know exactly what
I'm doing!
3VR1 VRAM size and speed
Again, it's the VRAM mode.
My docs tell me:
1 = 64k x 1bit / 64k x 4bit
0 = 16k x 1bit / 16k x 4bit
I don't know what the value on MSX is, I guess it has to be 1 all the time.
You can check the value by doing PRINT RIGHT$("000"+BIN$(VDP(8)),8) in
Basic.
1 indeed.
4CBcolour Bus direction (0=Output, 1=Input)
This one can also have 1 value, otherwise the VDP won't work (it might even
blow up!).
OOPS! Same seems to go for PSG register 7. 10xx or BANG!
The first time I laid my hands on an MSX I POKED the PSG register 7
directly... with 00xx!!! My 8250 sounds real bad when doing phaser
effects, so I presume perhaps I blowed something with that POKE?!?!?
5TP?Transparent from palette
If this bit is set color 0 isn't transparent anymore. As far as I know this
only affects the sprites. You know the use of it, don't you?
Yeah. I actually ABUSE this bit.
6LCS Lightpen Select (active 1) connected trough colourbus
1=lightpen, 0=no lightpen. Always keep 0 in current MSX configurations.

Re: VDP port addresses in ROM
Do you guys get the VDP port addresses from main ROM (at #0006) or you actually bang #9x ports directly? We all use #9x immediately. Unless we write a tutorial were we say that the standard asks us to use #0006 ;-) He is right. There is some MSX1 to MSX2 transformer which has different ports but we need the speed too much to read it from adress 6. And in Dos-environment we have to do some difficult interslot-read... nah, assuming #98-#9B is much faster, easier, clearer. Using address 6 forces you to always use the OUT (C),r form, but I've managed to cope with this in a clean way but... the setup interslot-read and unorthogonal incrementing-storing really makes me SICK. It's the worst part of the code and it's right in the beginning! 8:D And by the way, from MSX2+ on, those ports #98-#9B are standarized too. So if you directly use these ports, it will work, according to the standard, on every MSX 2+ and higher. And in practice, it will also work on every MSX, exept for those which are adapted to MSX2 with this very rare Japanese board. And as I have no access to these rarities... perhaps some other incompatibility would arise despite the effort! So #9x is the way. MARK 2 MSX Mailinglist.

EI/RETI (was Re: Accessing disk with disabled interrupts)
Should I disable interrupts accessing the VDP register directly? Yes. Like this: LD A,value DI OUT (#99),a LD A,register+128 EI OUT (#99),a Keep in mind that when executing an EI the interrupts will be enabled after the next instruction. So this is the way to keep the interrupts disabled as short as possible, which is always preferred (although not required). Nice tip. This reminds me of the EI/RETI pair back in the ZX era. The fact is that... ***I DON'T REMEMBER THE REASON!!!*** Is this tip used in MSX interrupts? Why (or why not)? ZX Spectrum used IM2. Is it legal to call 256 times #FD9F with interrupts disabled at VDP level? Absolutely. But it might re-enable the interrupt. You'll have to check that. OK. Is it legal to tell Disk ROM to stop the motor with VDP interrupts disabled? Yes. Basically the DiskROM has nothing to do with the VDP. Just keep in mind that there is a chance that they enable the interrupts. But not at VDP level I suppose. But why do you need to keep the interrupts disabled??? It was posted on this list that F700 had disk speed problems because of poor disk interrupts. One way to cope with this was disabling interrupts during disk loading. This way the F700 problem is solved at boot time without disturbing other MSX models and without the hassle of saving/RET poking/restoring the int vector. Kiss you lot. MARK 2 MSX Mailinglist.

Re: Text editor w/ varitabs
Is there any good text editor with variable tabs per line (for assembler readibility's sake!)? Well if you want a text-editor I suggest Ted, very good although it has Dutch menus, which may be a problem (but I think not). Why is it not available in plain english? It's not a big problem but feels a bit uncomfortable and gives software a bit too much of a "public domain" look. But if you're programming assembler: GO GET COMPASS!!! (Yes, I'm shouting!) I'll have a dekko at it (now I'm deaf btw!) 8;) ??? So you want different TAB settings per instruction??? My message was messed up (by your reader or my poster). I don't want different tabs per instruction but per line field. LABEL DJNZ LABEL; FOO LD A,B ; BAR That is, something like 8 spaces per colonless label (so you can fit it in the same line), 5 per instruction (the longer mnemonics HALT, DJNZ, etc. have 4 chars) and a suitable space for comments without touching the instruction paramenters. Well, if you want readability I suggest you drop your entire current layout and go start a new one: Mmm... me and the lot of 6502/Z80 coders back in the very early 80s were using that layout! See Terminator part 1 robot listings 8;) Foobar: lda,b djnz Foobar Some prefer to have the labels on seperate lines because it's easier when inserting/deleting instructions but I don't; the CTRL-L keycode of Compass is very useful. Just like me! It's a bit messier if you have a poor editor, which is not our case, huh? 8;) Also, I use lowercase characters for the code (but uppercase is nice too), and lower+uppercase-characters for Program-labels (like Foobar), and uppercade-labels for data: DATA: DB#FF Well, it's almost mandatory to use lowercase for 68000-like assembler, since it resembles a high level language: FooBarLongLabel movem.l d0-d3/a0-a2/a5,-(sp) * Foo bar loong comment eori.b #$25,$22(a0,d0.l) * Foo bar looonger comment That in uppercase would be DEADLY! But I personally prefer 8-bit assembler in uppercase. It looks more consistent, and opcodes ain't that messy to become unreadable. Again, see Terminator. Robot listins wouldn't be as impressive in lowercase 8;) I really hope you take over these programming-habits because it really makes your source much easier to read, it really makes a difference! As I've said it was a problem of TAB conversion between our mailing programs. My habits are just "classic" early 80s stuff: uppercase varitabs. Nothing that messy. They were actually stroking listings on teletypes so the code had to be real readable! *:D And btw I'm quite proud of my crystal clear assembler. I even don't put a single comment mixed with my code if it's not a matter of life/death! I prefer a short and clear header description, clear labels and equates, the right amount of "air" and choosing only the best way to do things (there's only one, so there's no chance of misunderstanding). I also prefer notes, diagrams and algorithms off the source, even though I'm proud of my ASCII art 8;) Kiss you lot. MARK 2 MSX Mailinglist.

Re: Those Microsoft coders...
Disassembling a standard MSX-DOS V1 boot sector I've come across the following: It uses a BDOS function 6 loop to output the boot error string instead of function 9 (!). Any reason? Yes. It probably is a null-terminated string, which sometimes is nessacary if you for instance want to display a '$'-sign, or when you are printing an ASCIIZ-string Dos2 uses for its diskroutines. But this string: C085426F6F74206572 DEFM"Boot error" 726F720D0A DEFB#0D,#0A C09150726573732061 DEFM"Press any key for retry" 6E79206B657920 DEFB#0D,#0A 666F7230726574 72790D0A Has not a single $. Neither DOS2 did exist. It's the bootsector as found in the Philips NMS 8250 MSX-DOS release *1*. I really don't understand the programming style of the bootsector. Really BAD habits. By the way, if you disassemble function 9 you'll see it's nothing more but a loop which calls function 6 until it encounters an '$'. I guess so, but that's precisely the reason to use 9 instead of reinventing it and the wheel! Haven't checked that but I'm quite sure, I know quite a bit how Dos is programmed and I really expect those kind of tricks of them. Tricks? To repeat a ROM function? To use JPs in loopless near jumps??? 8:? There're spurious JPs where it should have been JRs (!). Plenty of space??? *:D Well JPs are a bit faster than JRs. Speed is more important on MSX than space I think. Although in the case of Dos they don't seem to use that policy. But the mapperroutines are as fast as they can get. They get credits from me for that. Faster for an error branch (no S/M code)? Is the whole MS firmware this quality? :) Well looking to Windows...

Standard MSX-DOS bootsectors seem to set stack pointer at #F51F. Is that a safe address to keep using Disk BASIC calls within a bootstrapped program?

I've noticed rare sprite behavior when using graphics 7 (SCREEN 8) mode 2 sprites. 1) It's impossible to obtain opaque black (color code + active pixel on the pattern). True. You'll have to (re)set bit 5 in VDP r#8 (something like "Transparant mode enable"). It works! Thanks 8:D 2) "Bright" black (color code 1000) yields *ORANGE* (!!!). Color code 1000??? What do you mean with 1000??? Is it an RGB-code (which should then be 3-digit, not 4-digit), or is is a binary number (then state % or b in front of it)??? If it's binary then it's color code 8, and if I do COLOR 15,8 in Basic I get a red background. It's a 4-bit digital RGBI sprite color. To be precise, it's an IGRB color code (Intensity Green Red Blue) that works in gfx7. In other modes it's just a 4-bit index for the 16 color palette. 1000 should be an "intensity enabled" black, but yields pure orange on a MSX2. Attached is a tiny test. It shows 2 horizontal orange blocks when in theory it should be a solid opaque black square with two "bright" black strips. I've tested it only on 9938 VDPs. I'd appreciate if someone could test the program on later VDPs so I could make the assumption it works this way on all MSX models. On my v9938 VDP I saw a bright 2x2 green dot. On my v9958 too. Oh yes. And if you wiggle your joystick in port 1 you should be able to paint the screen with a smooth overscan scroll!!! But what *around* that green dot? black or orange stripes? or nothing??? By the way, this file only worked in Dos1-environment... Why??? Are you changing the memory or so??? Also (and that also goes for the overscan-demo), your programs reset afterwards... is it so difficult to execute a BIOS-call to select screen 0 again and the terminate the Dos-program (JP 0 or LD C,0:CALL 5)??? I just can test my programs in MSX2 computers running DOS1. They work 100% in those environments. I abuse the memory since it's just a quick and dirty test. I don't check for system memory boundaries yet -neither drive spin down-, sorry. The program indeed reselects screen 0 by using a BIOS call, but DOS2 memory is likely to be seriously trashed at this point. Hope to fix it in forthcoming tests. Watch out. Errm... Something completely different... I checked the Yamaha-site, and at the videoprocessor-part I read the following: Product: V9938 Display Type: CRT Display Format: Up to 512x424 Grayscale Colors: Up to 512 Output: Linear RGB Composite Video Up to 512 colors??? How did they think to do that??? I hope not using screensplits... It means a 512 color palette (9-bit RGB). And about the greyscale-bit... if I set the bit in one of the VDP's control-registers (0, 1, 8, 9) my screen does everything but turn grey. Dunno. Will test/investigate as well.

Re: MSX and gambling boards
We are an Italian company and we produce coin-op boards and software. Since the capabilities of the embedded boards that are normally used for the delivery of gambling software are very limited, we would like to check if it could be possible to integrate an MSX computer on a JAMMA-standard board (the JAMMA connector is the standard connector in this field). Aha! Sounds like an original idea! We already had this idea. See my previous postings. A vertical display flavour of our videogame will be presented next AAM MSX user meeting at Barcelona running on an impressive MSX JAMMA coin-op cabinet. If someone could supply a cabinet at the forthcoming fairs in Japan we also could present the Japanese vertical version. Kiss you lot.
