i have an (official) Assimilate cart. it has a unrom 512 board. i have a copynes system. i'm trying to build a nes rom from it. this is not the full version rom available on the official site- that is a mapper 1 rom.

based on the pics, i gather the dumped rom should be specced as

mapper 30 (?)
2 mb prg rom
32k vram
not flashable/no battery

i dumped this using the uorom setting to force it to 2 mb. it *appears* to work. is there any issue with that? do i have the other values right?

I don't think Assimilate bankswitches the CHR, so I'm pretty sure it would work as mapper #2 also (8kB RAM chips are just hard to get). But I suppose it never hurts to have the header match the hardware. Seems about right to me.

thanks. i watched some writes with the fceu debugger and it does seem to change chr ram banks. notably the opening cutscene right after start is garbled if set to mapper 2. i didn't watch further but since the 32k pads are connected i'll leave the rom header as 32k. so this is what my assembled rom looks like in famirom

Code:
Assimilate (cart version).nes
iNES ver.: 2.0
 platform: NES
   mapper: 30
mirroring: Vertical
 prg size: 256KB (2mb)
 chr size: 0
  chr ram: 32KB vram
  battery: no
  trained: no
   timing: NTSC
expansion: Standard NES/Famicom controllers
boards: (version not supported for guessing)
CRC32
      prg: FE7015EC
     data: FE7015EC
     file: 7986F78F
