notes: |
|
|
Nestopia UE is a cycle-accurate NES/Famicom emulator. The libretro port
|
|
tracks the upstream Nestopia JG project. NES cartridge games need no BIOS.
|
|
Famicom Disk System games require disksys.rom (8 KB FDS BIOS) in the
|
|
system directory. The core validates the BIOS via CRC32 against two known
|
|
dumps: standard Famicom (0x5E607DCF) and Twin Famicom (0x4DF24A6C). An
|
|
unknown BIOS triggers a warning but still loads.
|
|
|
|
NstDatabase.xml is an optional game database for region autodetection,
|
|
mapper selection, and 4-player adapter recognition. A copy is baked into
|
|
the core binary (libretro/nstdatabase.hpp) as fallback. The upstream
|
|
Nestopia JG requires this file; the libretro port makes it optional.
|
|
|
|
An optional custom palette file (custom.pal, 64 RGB triplets) overrides
|
|
built-in palettes when the nestopia_palette core option is set to Custom.
|
|
The libretro port embeds all named palettes (Royaltea, Smooth FBx, etc.)
|
|
that the upstream loads from external .pal files.
|
|
|
|
Five Famicom games use external ADPCM audio samples placed in
|
|
system/nestopia/samples/{game}/ as numbered .wav files. These originate
|
|
from MAME sample ZIPs. Games function without them but miss some audio.
