Hooked up TC0091LVC to Fruit Dream driver, and after a bunch of silly bug-fixes, here’s the results:

Started working on Last Bank, that is a TC0091LVC-based bike gambler HW with many (not every) resemblances to Taito L HW. Basic graphics and inputs are hooked, but most charset (tiles and sprites) are missing for unknown reasons (bad dump?) …

EDIT (21-Jul-2012): Smitdogg provided an overlooked gfx ROM, and I’ve implemented almost every single feature missing from the new TC0091LVC device core (that will be ported to Taito L system at some point as well):

Thanks also goes to Haze that helped me with a gfx decoding issue that I was encountering on the device-ization process.

hap and me emulated Flipper Jack, a rather unknown pinball game by Jackson with unique HW.

Colors are quite off, needs some reference to get them right.

Understood and hooked up sound HW in Little Robin, that is a weird combination of 2 DAC sound chips, the video scanline register, interrupt generation (irq lv 4 with an input port that defines the kind of irq, currently hooked up with the video frame number) and two lovely 16-bit port registers (one for each DAC) that alternates the resulting 8-bit sound index according to an external source (frame number % 16 with current implementation, as each “sound irq” happens every 8 frames). And by alternation it means in the sense of muxing between LSB or MSB of the aforementioned sound index (that is obviously pointless if isn’t a form of protection).

It’s no secret that the team is currently doing major efforts in emulating PC-AT based HW. Grull Osgo in particular is working on California Chase, that is currently more or less working with a “MS-DOS” kludge (you need to type boot after that Win 98 fails to boot). I’ve tweaked the code a little and added an idle skip for it.

Street Games 2 recently started working after some tweaks to the VGA code:
