Profiles that read two repositories, a libretro port and its upstream, now prefix each citation with source or upstream, decided by which tree carries the cited value at its pin. The emulator pages use the word to tell libretro glue, emulator code as the port carries it, and the upstream emulator apart.

High-accuracy SNES/SFC emulator with Game Boy/Color and Super Game Boy
|
|
support. Upstream archived at 0.4.0, superseded by Mesen2. DSP firmware
|
|
can be loaded as combined files (dsp1.rom, dsp1b.rom, dsp2.rom, dsp3.rom,
|
|
dsp4.rom, st010.rom, st011.rom) or split program/data ROMs. Combined
|
|
files are tried first, size validated. HLE coprocessor option available
|
|
for DSP-1/DSP-1B only (libretro core option mesen-s_hle_coprocessor).
|
|
CX4 is fully HLE, no firmware needed. ST018 detected but not emulated.
|
|
GB/GBC/SGB boot ROMs fall back to embedded open-source SameBoy boot ROMs
|
|
when external files are not found.
