RE: Sprite pointers - mixed and scrambled
The actual bit settings of these registers are depending upon the current screen mode. This is the calculation in NLMSX: Screen 1, Screen 2, Screen 3 (Sprite Mode 1) Tables-SpriteAttribute = MSXVDPVRAM + ((MSXVDPRegisters[5] 0xff) 7) + ((MSXVDPRegisters[11] 3) 15); Screen 4, 5, 6, 7, 8, 10, 11, 12 (Sprite Mode 2) Tables-SpriteAttribute = MSXVDPVRAM + (((MSXVDPRegisters[5] 0xf8) | 4) 7) + ((MSXVDPRegisters[11] 3) 15); Tables-SpriteColor = MSXVDPVRAM + (((MSXVDPRegisters[5] 0xf8) | 0) 7) + ((MSXVDPRegisters[11] 3) 15); The last three bits of register 5 have to be '111'. And you really must write them into the register. Try it otherwise and you will see that it does not work in the way that you want it to. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Jorge Sent: Tuesday, October 12, 1999 6:14 AM To: [EMAIL PROTECTED] Subject: RE: Sprite pointers - mixed and scrambled R5: A14 A13 A12 A11 A10 1 1 1 Graphic 3 Mode (Screen 4): R5:A14 A13 A12 A11 A10 A9 A8 A7 Weird!

Any volunteers? And about that screen 0-shift routine: thanks Daniel! I'll try it when I can. I had another idea for a solution: do something like LOCATE 60:FILES"*", so that the . and .. will be on a seperate line. This line can then be skipped or erased... This is fairly simple, but unfortunately it doesn't work: FILES always does a locate 0 (or CR/LF) before outputting... Shit. So, they only usable thing is Daniels ML proggie... But Daniel: I don't have CL80 nor a MSDOS computer. But I guess I can compile it on a MSX too?

RE: Two questions!
BTW: Does anyone have info on the filestructure of an MBM file? (Especially the 'header' part, where the songname, drumkit name etc is) If you look at the replayer source, you can find out the header structure without much trouble. Look at the "start playing" routine, it LDIRs most of the headers to the settings variables. Look which bytes are copied where, and then look at the settings variables (their labels start with "X"). Anyway, the songname and drumkit are real easy. They are fixed-length strings that always occur at the same offset in the file. Take a hex editor and you can't miss them. About drumkit: - sometimes the value listed is "NONE" (none + 4 spaces), this can either mean there is no drumkit or that it was not properly selected by the composer - sometimes the value in the drumkit field is not correct (the file doesn't exist) So you should make your player handle "file not found" on drumkit loads. A trick I used to get the drumkit right more often, is to look for a drumkit with the same name as the song (LALA.MBK if the song is LALA.MBM) in case no drumkit is specified or the specified drumkit doesn't exist.

Its value is set from LINL40 or LINL32 whenever the VDP is initialized to a text mode via the INITXT or INIT32 standard routines.

The computer understand the memory always as 80 columns! If you write a word in the 0,0 position, in 80 columns, it will be, in the memory, this way: word (actualy, the "0" are 32 - or spaces, if you preffer. I used 0 to save space). if you write this word in 79 columns, it will be the same on the VRAM (but the last position will not be available from BASIC/System PUTCHAR isntructions): word But, if you use 78, it will not be the same. It will be (again, the last position will not be available from BASIC/System PUTCHAR instructions): 0word000 and the same for 77. For 76, it will be (now, the last (for 77) and the two last (for 76) positions will not be available from BASIC/System PUTCHAR instructions): 00word00 and so on.

Re: Sprite pointers - mixed and scrambled
Well, as you can see it's not very clear what the actual bit configuration is, particularly that of R5. Any of the docs I've checked so far brought any light on the subject (the 1 1 1 thingie as Laurens pointed being my main concern now). I'll carry out some investigations on the BASIC side of things. Well in fact my docs (and I think the official ones too) state those three 111s to be A9, A8 and A7. However, experiments showed that it doesn't work on the most-used screenmodes when those bits are not set. As well as a lot of other registers, setting those bit to another value than 1s will cause some kind of 'repeat'-effect. With the 'set screen' register, you can make very nice use of this effect because using that you can copy the 1st 8 lines up to the first 128 lines to several other places in some kind of repeat over the screen. This way you can create 26 (.5) equal scrolls below eachother without any hard tricks like lots of screensplits etc. On a side note, being a complete newbie to the MSX scene as I am I find rather surprising there's still disagreement on what could surely be referred to as 'the basics' of vdp programming. Well if something doesn't exactly work the way I want it to be I always keep in mind it could be another form of the effect stated above. And I try out how it works, and how Basic does the trick. I don't think there is disagreement. Some people just haven't tried it before but are simply stating right from the manual. It's just that the official manuals aren't right everywhere. Now it seemed that the manual WAS right, but seemingly only in mode 3 (that would be old MSX1 multicolor mode?). Back to my badly typed docs then. Hey I whish there was a 'COMPLETE AND ABSOLUTE GUIDE TO HARDWARE BANGING THE MSX' in the old style of, dare I say, the Amiga days. Yep, it ain't really there. Too bad. But I think I have most tricks - or in my head, - or somewhere in a documentation. And that goes for most MSX programmers I think.
