Differences between OPL2 and OPL3 in OPL2 mode are quite subtle and are not audible. Also DOSBox default OPL core does things closer to OPL2 rather than OPL3.

Nuked OPL3 v1.8 is out. Changelog: * New envelope generator. * Rhythm mode emulation is 100% correct now. These and other aspects of chip have been verified on YMF262 die shot, so emulation should be perfect now. P.S. For some reason i can't edit topic's header. So i'll attach patch here.

OPN2 has this bug too.(YMF276 variant at least) Here's my test code: for(int i = 0; i < 0x200; i++) { writereg(i,0); } writereg(0x34,0x03); writereg(0x3c,0x01); writereg(0x44,0x0f); writereg(0x4c,0x06); writereg(0x5c,0x02); writereg(0x64,0x00); writereg(0x6c,0x00); writereg(0x74,0x00); writereg(0x7c …

Thanks again 😀 It's interesting that OPL2 has this bug. I wonder does any other Yamaha FM chip family has this bug.

I cannot hear a difference between the 3 sound cards I recorded from. I ran the program under Windows 98 SE command.com Interesting results. YMF744 has real OPL3 so no question here. CMI8738 is believed to have real OPL3 and this recording confirm it. But ESS1938 is surprising. Perhaps they were …
