No.05455 Kold666 Developer Jan 7, 2010, 23:55	ok, I'll check again when bug 03630 will be fixed
No.05462 Haze Senior Tester Jan 8, 2010, 21:04	03630 afaik relates to the eeprom device. these are using battery backed ram, not an eeprom. that said, they are already marked to save NVRAM AM_RANGE(0xf000, 0xf7ff) AM_RAM AM_BASE_SIZE_GENERIC(nvram) /* battery backed RAM */ although I do question what this is static READ8_HANDLER(f6a3_r) { if(cpu_get_previouspc(space->cpu)==0x8e) space->machine->generic.nvram.u8[0x6a3]=1; return space->machine->generic.nvram.u8[0x6a3]; }
No.05467 Tafoid Administrator Jan 9, 2010, 11:56	I'll close this for now. If it happens that there continues to be an issue, please reopen, Kold.
No.05486 Kale Developer Jan 11, 2010, 12:34	@Haze: these 8741 games do a comm check for every vblank cycle, if that memory returns zero then the game hangs, there's a similar loop in Cycle Mahbou as well.
