You did? What did you do to the memory register? Or did you make it just like Robotron? That's what I did at first, but it gives you a black screen.
Well, if it's emulated, good, if not...oh well.
TheGatesofBill:
I did it in the wee hours of the morning, I'll try to figure out what I did though (or if I was just hallucinating). At this point the only thing I can remember about it is working on it. Looking at the page again, it does look like some things were changed in the hardware (one board changed, one board added), and therefore something will need to be changed in / added to MAME.
Okay, I just looked up my code:
--- Code: ---ROM_START( wmg )
ROM_REGION( 0x80000, REGION_CPU1, 0 )
ROM_LOAD( "rom_512k.bin", 0x0000, 0x80000, CRC(975516ec) SHA1(571aaf9bff8ebfc36448cd9394b47bcfae7d1b83) )
ROM_REGION( 0x17000, REGION_CPU2, 0 )
ROM_LOAD( "snd_32k.bin", 0xf000, 0x8000, CRC(1d08990e) SHA1(7bfb29426b3876f113e6ec3bc6c2fce9d2d1eb0c) )
ROM_END
--- End code ---
No idea if it makes any sense, or what I changed. However, trying to load it does just go to a black screen. I need to stop working at things really late at night.
SirPeale:
Looks like you changed the ROM REGION. I think the memory handlers need to be addressed. Not exactly sure how the multigame daughtercard handles all this. Perhaps selective addressing.

It's a longshot, but perhapse he would be willing to answer some of these questions if we e-mailed him.
Maybe he would spare us a clue?
I would ask him but I don't speak code.
