NESDev wiki and NesCartDB want all Camerica games, except the Quattro multicarts, at Mapper 71. NESDev wiki also assigns a submapper to Fire Hawk's one-screen mirroring. Why?
The two new Dizzy games (Wonderland Dizzy, Mystery World Dizzy) released by the Oliver Twins are set to Mapper 2, even as Wonderland Dizzy retains the CIC stun code. All Camerica games other than Fire Hawk and the Quattros work nicely as Mapper 2 (UNROM). The additional latch register range from $8000-$BFFF and the CIC stun register range from $F000-$FFFF do not seem to throw UNROM emulation off the rails in any emulator except FCEUX, and the latter is thrown off because it always emulates bus conflicts. If the point is that UNROM has bus conflicts while Camerica boards don't, UNROM's submappers already account for this.
I found this question asked once before, but not answered. My motivation for asking is that the Everdrive N8 does not support submappers and requires the Camerica games at Mapper 2 except for Fire Hawk and the Quattros, and doing so seems like a sensible idea in general.
