Re: Speeding up Interrupts...
Hello! I want to speed up the interrupt (original #38). So I use the #FD9A for jumping to my own routine (which will pop the return-adress from the stack), checking the Vertcal- Blank flag and only the absoult necessary things. Everything is fine, BUT - there are still two things which I would like to remove... the call to the old #FD9A, and the call to #FD9F. #FD9A: called on every interrupt which occurs, normally not used by the system, only some special software. - there shouldn't be problems if I won't call this old entry #FD9F: called 50/60 times per second, a restard-command to stop the diskdrive. - before disabling this call, I will call it 256 times after a diskoperation to stop the drive. What is your opinion? Will I be in troubles by removing this two calls? thanx in advance for your help greets wolfgang You can also create your own ISR, using another Interrupt Mode of the Z80. The good side of *this* method is that you still can use the BIOS routines. Let me show you how to do it: - Create a jumptable, starting at a 256-byte boundary (i.e. #C000, #C100, etc), containing 128 times the start-address of your ISR-routine. Note that the high- and low-byte of this address should be the same (for safety). (i.e. #D0D0, #CFCF, etc.). - Put the high-byte of the start-address of the jumptable in the interrupt-vector register (i.e.: LD A,#C0 LD I,A). - Switch to interrupt-mode 2. Here's an example: ; --- Switch to own ISR di ldHL,#C000; start address of jump-table is #C000 ldDE,#C001 ldBC,256-1 ld(HL),#D0; start address of ISR is #D0D0 ldir ldA,#C0; let interrupt-vector point to #C0xx ldI,A ; (xx = variable!!!) im 2; Interrupt Mode 2 ei equ #D0D0 ISR: ; your ISR This code is from the top of my head, but I think this'll do. Note that you took over the complete ISR! So, save the registers onto the stack yourself, check whether it's a VDP Vertical Retrace interrupt, etc. Also you have to take care of keyboard-input yourself. No default handler will do that for you anymore, since these handlers run under interrupt as well. Hope this helps! Greets, Jan-Lieuwe Koopmans MSX Mailinglist.

Re: AW: msx-ers
You are right about that. They not only "rediscovered" the Music Module, but also did something else: the use of FM Pac. Ehm, but not in FST 1, AFAIK ! And (again AFAIK) FST 2 was released _after_ the first version of MB. But I must admit that without FST the MSX scene would probably have died long ago... Wrong! FST 1 *DID* support FM-Pac. Just not simultaniously (call it "stereo") like MoonBlaster does. The FM Pac (or the MSX Music in particular) was very popular and there was no program to use it, except the FM Basic and a terrible program from MSX Engine (was it called Music Composer??). Uhm... Studio FM, I think... Really buggy indeed. Gave up on it after a few attempts to create "something" (but all these sessions ended up in an MSX logo scrolling up smoothly, without me hitting the reset button). I've never seen that thingie. Just heard some musics made with it. I got the feeling that you could do more with this Engine thing than with FST. Probably right; FST was obviously dedicated to the Music Module. The FM-Pac support was more like an "extra". Eric (once 4TRAX member) So... Is Frank Thijsen (another 4TRAX member) still alive? Greets, Jan-Lieuwe aka MOA MSX Mailinglist.

Re: Divide Multiply in assembler
Come on! Your VDP had got its own Line drawing instructions... You don't need multiplications/divisions for those... Why don't you use these??? Hello fellow-MSX'ers! I need FAST division and multiplication routines in assembler and I hope some of you can help me. I need an integer division (rests should be ignored) that does DE / B (or similar). Where E is always zero (maybe that helps?). I also need routine that does DE * B (the lower 8bit are discarded, if that helps). The catch with these routines is: You CAN NOT use exchange instructions (EXX, EX AF,AF') and you CAN NOT use IX or IY. I need both of these routines to draw a line between 2 coordinates. If someone has such a routine (and if its FAST) I'd be interested also. Thanks in advance! Patriek ,--. ,---. ,--.

Re: PLAZTIK.BAS !!!!! :(
i've downloaded it and try to run it from fmsx-dos 1.6b2 and it wouldn't run at all. I just got the computer screen filled with a light purple color and then it hanged. Anybody has experienced the same frustration? :( That's what I get when I run the corrupted version. You can determine if you have the corrupted version if you do "LIST"... you see garbage in the last few lines. I tested the demo on fMSX 1.6b (maybe even b2), and it works fine with me. I also tested it on a real MSX (NMS8245). Maybe you can determine which error occurs by typing 'SCREEN 0' in this purple screen and do "? ERL" (you get the error line) and "? ERR" (you get the error number). You can see what the error number means by entering "ERROR error number". I really don't have a clue what might cause such an effect other than having a corrupted file. If you run it withouth KUN-Basic (at 100% or less Z80 speed), it might take a while before the effect is visible... Maybe that's the case? Note: This demo won't run under KUN-Basic when you do "CALL RUN" or "_RUN". Instead, remove the 'REM'-sign before the _TURBO ON and _TURBO OFF.

Re: Basic Demo Compo Rules. FINAL VERSION ??
Again a remark I made before: 2) Basic accelerator: - not allowed if they don't come with the standard you are using (msx 1/2/2+ or tr) So: this will totally outlaw any compiler, since there's never been a "standard" compiler. Suggested rule for compilers: -ONLY XBASIC/KUN-BASIC: using CALL TURBO ON and CALL TURBO OFF to activate or deactivate compiler. -No use of extra features of compiler, just plain basic I've never used NESTOR BASIC (heck, I've been too lazy to look at its features) but if it is XBASIC/KUN-BASIC compatible this is also accepted. You might wonder why I want the use of a compiler be "legal". Simple: since the day I heard about it's existence I've been using this piece of software for almost any graphical program I made for MSX. Because of the nature of compo-demo's which are usually graphic to get the most stunning fx, the use of compiler is required to make these effects even possible. I really wonder what your basic-programs WITHOUT compiler look like, but mine will look really SHIT and will take WEEKS to finish precalculation... I would like to hear other opinions about this problem. Randy I agree... Plain BASIC is unsuitable for high-speed nifty FX, unless you precalculate everything. KUN-BASIC will eliminate the problem... either realtime calculation can take place or precalculation will only take some seconds. It's both an enhancement for the voters as for the graphical effects which will be implemented. And that's what we want, right? Nice demo's! Greets, Jan-Lieuwe MSX Mailinglist.

Re: Basic demo compo

(I know somebody did something similar yesterday, but I think we should do things more official...) Maybe I (or someone else) can dedicate a (sub)page to to contest, where people can find the rules, restrictions, deadlines, etc. Then we can also put the final demo's for downloading down there. The URL can be posted to comp.sys.msx and alt.comp.msx... something like: "Wanna show the world your BASIC-skills?

I think i will be a nice *match*!!! Of course in Basic mean without an ML or related instrunction like Poke,Peek,Vpoke,Vpeek,In,Out,Usr,Data etc. I don't know is right to exclude also the Vdp instrunction. I don't think, that VPOKE, VPEEK, VDP and DATA commands has anything to do with ML. IN, OUT and WAIT commands are also not for ML proggrams, but anyway they should maybe leaved outside of this competition. Maybe also all CALL, BLOAD and '#I commands should be forbidden exept BLOAD"XBASIC.BIN",R and _TURBO ON/OFF, if we use XBASIC. First of all I'd like to say that I think this a good idea... I don't think the DATA and POKE commands are a problem if you ban the USR command, so I think both DATA and POKE (and PEEK) should be legal commands in the contest. VPEEK and VPOKE are the only commands to read from/write to the video-memory, and they really haven't got anything to do with ML. The only alternative would be POINT and PSET (but that's not a full 100% alternative). IN and OUT (and VDP), really haven't got *ANYTHING* to do with ML. IN and OUT just let you write or read data through a port. The VDP command let's you write to VDP registers. Basically the only ML related command is "USR". Ban this one and you get pure basic. So, we should make a list of banned commands, legalize KUN-BASIC (XBASIC) or not, pick a deadline and an upload FTP-site, and off we go! P/S: BLOAD should also be legal, as long as you ban the ",R" switch. How should I otherwise load binary data into (video)memory??? Greets, Jan-Lieuwe MSX Mailinglist.
