notes: |
|
|
FCEUmm (FCE Ultra mappers modified) is a NES/Famicom emulator.
|
|
NES cartridge games need no BIOS. Famicom Disk System games require
|
|
the FDS BIOS ROM (disksys.rom, 8 KB) loaded from the system directory.
|
|
Game Genie emulation is an optional core feature (disabled by default)
|
|
that requires gamegenie.nes in the system directory.
|
|
An optional external palette file (nes.pal, 192 bytes, 64 RGB triplets)
|
|
can override the built-in NES palette when the core option is set to Custom.
|
|
NstDatabase.xml is NOT used by FCEUmm (that is Nestopia's database).
|
|
|
|
File path construction: src/general.c FCEU_MakeFName() joins the
|
|
system directory (RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY) with each
|
|
filename directly - no subdirectories.
