Mapper 251

Post by zeroone » Tue Jan 10, 2017 6:15 pm

The following ROM from GoodNES3.14 is listed as Mapper 251:

Multi-Game Pirate Carts.7z <Super 8-in-1 99 King Fighter (Unl).nes>

That mapper does not appear to work in any emulator. It looks like it's a variant of Mapper 45.

Does anyone have more information about this mapper or the origin of this ROM?

<Super 8-in-1 99 King Fighter (Unl).nes>?
Well, my first hunch was right, CaH4e3 did at least something, but I can't really find any more on it.
CaH4e3's site wrote: Past Changes (november 18, 2005):
  • UNL-SuperHIK8in1 unif board - (...) UNIF wrapper for "Super 8-in-1 99 King Fighter [p1].nes" converted to UNIF format with correct CHR banks order.
…then FCEU Bizhawk source says that SuperHIK8in1 is completely unaltered mapper 45.
So I expect the ROM is just a CHR-bank-shuffled mapper 45?
