Added support for the CuRAM-16 XMS card to the PS/2. The Model 80 isn't fully compatible with it but the IBM first-party RAM expansion cards have option ROMs and no documentation. This is enough to install and run Doom (...on a 16MHz 386.).



I have a bunch of cards emulated now. The Sound Blaster MCV's FM audio works but digital audio crashes the emulated system.



Also working on the M-ACPA DSP card. I don't have any of the analog section hooked up yet but the DSP communication works.

Had that patch from a while, it wasn't that good prior to new68k.
Some other protections relies on CIA timings, which in turn needs Agnus DMA penalties & waitstates.

FL Gun Professional is the Japanese version. Gunfighter (no "FL") is the export version. There's also a French/Canadian version called Duel.
I'm 99% certain it's the same game, to make it 100%, one would need to look at the pcb of the Japanese version and see if it is the same MCU rom serial number.

I mean, if there was low hanging anything in the Commodore drivers they'd be in better shape.

Now that you mention - the range won't exceed the supplies available. I think mostly these particular voltages go through op-amps on the +-15V rails, so signed 5.27 or perhaps 8.24 would be plenty of both range and precision.
