Needs discrete sound emulation instead of samples.
Sound is too high pitched.
Konami GX based PCB for gambling games.
Sound isn't hooked up (probably discrete).
stepstag, steps3, vjdash - No music ROMs / HD dumps.
Unemulated Yamaha YMW258-F sound chip (possibly identical to MultiPCM?).
Needs converting of the SSI-263 to a sound device and laserdisc audio.

The emulation of the Custom Imagetek I5000 chip isn't perfect yet.
glfgreat, glfgreatj - Sound hook up isn't 100% correct yet.
Preliminary driver.
outzonec - Z80 roms is probably incorrect for this set, causing wrong sounds.
jujuba - In this bootleg sound hardware seems to have been slightly modified, the coins are handled ok, but there is no music and bad sfx.
Sound is hooked up according to schematics, but it sounds horrible. It's supposed that real hardware differs from schematics.
hyprolymb, hyprolymba - Bootleg with different sound hardware, which isn't correctly hooked up yet.
Preliminary driver. Unknown CPU. Possibly G65816 derived?
Audio is almost there, but not perfect yet.
funkyjetb - PIC has been decapped but hook-up hasn't been completed yet.
pangpang, tumbleb2 - Sound PIC is protected and simulation isn't 100% correct. We need a dump of the PICs.
tumbleb, tumblepba - Sound is not quite correct yet.
Driver needs discrete sound emulation instead of samples.
Speaker doesn't produce correct sound due to bugs in the via6522 emulation.
Sound isn't fully hookep up yet (IDE DMA, finish comms).
