I made a discovery...

None of the emulators emulate YM2612 "wait before write bit" correctly. I was messing with my WAVPLAY programs on real HW and discovered that MD can't play samples over ~33KHz but on emulator you can go over 96KHz !!! For example, on real HW if I remove delay loops, the sound plays at ~33KHz but on ...

Whats wrong with trackers ? I love trackers !!!

I've been thinking of writing MOD player for MD. First 68K version and later z80 (when I start z80 programming) version (for games). I hope z80 is fast enough...

Yes thats true, name table cannot exceed 8KB. But why would you use so big name table anyway ? I use 64x32 and thats enough for me at the moment.

Its not a Flash cart, its SRAM, it uses RAMs not ROMs. Anyway it is great thing to test out stuff. BTW your spinning cube works great on real hardware !!!

As I said, make the game first, then add SFX and BGM, like I do know. Yesterday I got GBMD to make sound (samples). Maybe download it from my site and listen the result...
Anyway don't quit because of it !!!

I do my testing on the real hardware now, I specially built a SRAM cartridge for such purpose (pics on my site). 256KB of unlimited rewrites, programs in 5 secs, 3 in pure DOS. Program with my MPCP (damn, off topic).

I did my 512 and 960 color test without DMA. Results are good on emu but suck on real thing. Maybe DMA helps... source for 960 color demo available on request.

Silpheed is very impressive (I even have original CD but no MCD). Background is FMV for sure, sprites and stuff I'm not very sure if they're generated by MCD 68K or MD 68K. Who has beat that game ? Last boss is difficult (damn, off topic...)

Don't worry, my games doesn't have music nor sound effects yet but they're still quite enjoyable. I've been working on music stuff but due to my lazyness these are not finished yet.

Intro is very nice. I never thought that MD is fast enough to create such complex 3D objects.
Well, I'm not sure, but game itself uses raycasting. Edit: No raycasting, 3D objects all the way.

Actually, I don't find the 68k especially hard to develop. 68K is the BEST processor I know, x86(used in PCs) sucks compared to it(x86 has nice features though). I even don't miss high level languages when coding for 68K. NES is very slow and I only way to write anything decent is ASM (with lots op...
