Anyone happen to have TmEE's VDP calculator?
I found Pascal's VDP calculator and I wanted to try out TmEE's as well but the link is dead. I just wanted to try it out, I like having dos stuff.

I have to say...
Although this forum probably isn't as lively as it once was. Everyone here has been really helpful and tolerant of my noob mistakes. I just wanted to thank you guys real quick. Now, more work to do.

Well after your suggestion I tried 0x0c81, 0x0c87, 0x0c06, and 0x0c00 in the main program code, and all values result in black screen. At least now, I know how to better manipulate the VDP. Thanks for pointing me in that direction.

Colors way too dark in 0.97 on certain roms.
Hi there. I'm working on an M68k music tracker for the Genesis. In preparation for doing the GUI I was testing loading palettes to the VDP. Although I'm not too sure I was able to successfully load a palette (which is surely my fault), I was able to successfully fill the screen with a color (any ...

Nice to know, that makes this project seem a lot less complicated, although I know it will still be complex. At least Algebra is painless.
I understand what you're saying. I've thought of ways I could use 68k to do something useful, beyond apparently just moving bytes around. Something like, read ...

Well I think you've given quite a comprehensive explanation as to why my attempt didn't quite work. That primer book is very useful and easy to understand. Thanks to all your help I can move on to the next step and continue to learn this fascinating language.

Ahhh so basically that code was basically a bit sloppily done (no offense to the original coder of course) by a coder who was relying on the assembler to do optimizations.
As for vtimer, I figured I'd have to declare that variable, I just wasn't sure how to go about it properly in asm (I attempted ...

I'm using no startup code. The code above is all I have. So basically I need a header and code to initialize the genesis before this code can even be used right? I was hoping I could just jump in and start learning and toying with 68k without having to do all that. I'm using asm68k.exe.
Although I ...

Regen might not like that because based on the genesis memory map, you'd be writing to ROM there. Genesis RAM starts at $FFFF0000 and lasts till $FFFFFFFF (64kbytes). Try that out and you can peep in Regen's RAM viewer to see it work.
