I've took a big one on here. Started looking at Taito Z hardware. It's full of custom chips but things are moving along quite well. I'm looking at Chase HQ first. I have both 68000s running and the Z80 and the sound works. I have a lot of the graphics working but everything is still preliminary with a lot of work todo. The status is approximately;

• 68000A - 100% emulated
• 68000B - 100% emulated
• Z80 - 100% emulated
• YM2610 - 100% emulated
• TC0110PCR Palette Chip - 100% emulated
• TC0220IOC I/O Contoller - 100% emulated
• TC0140SYT Sound Controller - 100% emulated
• Sprites - 100% emulated - zooming is supported
• TC0100SCN Tilemap generator - approx 20% emulated, Bg Layer and Char Layer which gets chars from RAM work but are missing scroll, row scroll and column scroll. The foreground layer isn't emulated at all yet.
• TC0150ROD Road generator - approx 50% emulated - Road A works fine but I haven't touched Road B yet.

Once I have everything working well I'll tidy it all up and look at the other games on Taito Z hardware and then I'll move onto the next Taito board!
