I agree with you. I have that doc too, and I didn't find it very useful. Go check out CMDs docs, these give you enough inf to write a nice game. But sound driver needs to be written by you (if you're unable to get an suitable driver).

Ok, i've tried that reg in any possible way, before, after, byte, word and long access (latter to on even addresses of course). Still nothing, I have no idea what I'm doing wrong(?). I'm typing this by heart so there might be errors: Codestart: MOVE.L #$100001, A0 ; load address MOVE.B #1, ($A130F1)...

You can take an old broken genesis motherboard and uses it YM2612 chip. I wanted to do that with my old japanese megadrive but i'm not experienced with electronicals stuff... Actually I removed the YM2612 compatible chip from my fried pirate MD, but the chip itself is little fried... in Estonia the...

it doesn't have "self feedback" for the first slot. As far as I know (and tested), OPL2/OPL3 have 8 levels of feedback on their operators. The YM2612 is 2 YM2203 and a 8 bits DAC in a single chip. OPL3 has some form of 8-bit DAC but it cannot be used when FM sounds are enabled (that DAC sounds like...

How close is standard Adlib to the YM2612?
Actually they're not very close, but programmed in similiar way, 1 port for reg index, 1 for data. OPL3 is more close than OPL2 as it has two reg sets and can do stereo but that's all.

Learning Z80 assembly and how YM2612 and PSG works. Try getting an old soundcard with OPL3 FM synthesizer and try programming it, YM2612 and OPL3 are programmed in similiar ways.

No need for any editors, I wrote a program for that. Just type SMDTMSSP name_of_the_rom.BIN and TMSS added. Never do it twice on a same file.

Damn, I forgot to check if NOPs work, I was too busy testing my games and stuff on real hardware. My method definately works on real HW.

Is there such thing...

Saturday I built a tiny 256KB (2Mbit) SRAM cartridge for use with my MD cart R/W device and MD itself. I tried to run some of my demos on MD but they didn't run as I forgot to add 'write "SEGA" to reg' code in them and sources got lost. Then I wrote a TMSS patcher which puts 'write "SEGA" to reg' co...

Ripping can be quite pain, first you must find the track, second you must find the sound driver or exa´mine the track and write your own driver.
Anyway, my game, Glass Breaker MD is almost complete and I'm going to start writing BGM/SFX engine for it as soon as I learn z80 ASM.
