The rom folder survey joined 463 folders to their default core's whole profile, no system of it matching. SYSTEM_ALIASES, the one table _norm_system_id reads, now folds ten more spellings of one machine: apple2gs, astrocade, astrocde, creativision, gamepocketcomputer, nintendo-super-game-boy, cps1, cps2, cps3 and pgm. The profiles that used them take the canonical id (mame, groovymame, mamemess, mame0258, mame0278, bsnes, mesen-s, mesence, jollycv, fbalpha2012 and its three CPS cores, fbneo_cps12), as test_system_ids requires. With bsnes and bsnes-hd now filing SGB1.sfc under one system, their claims fold onto one report entry. _names_content read only the first claim, hashless, and nSide's SGB1.sfc/ tree took the path before the file. A hash on any folded claim now counts: every pack keeps the destinations it had. The site drops the eight display names the canonical ids replace and names tvgames. README counts 533 systems instead of 541.

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 Upstream archived at 0.4.0, superseded by Mesen2.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.
