muOS names its GBA folder gameboyadvance first, which resolved to ares's game-boy-advance. mgba lists nintendo-gba, so the fallback set was empty and an unrecognised GBA game got no file. ares, dgen, picodrive, fbneo, fbalpha2019 and emux_sms now use the ids the other profiles use, with their old spellings kept as SYSTEM_ALIASES (bios.sms and fbneo's Spectrum sets had fallen to the other bucket of the RetroArch list). A folder whose name spells a machine its core does not run now also holds the core's machines: a PC Engine CD folder run by mednafen_pce_fast got no System Card. Install lists and install/games regenerated.

Mega Drive emulator for SDL by Joe Groff and Phil K. Hornung, carried on by
|
|
zamaz. Release 1.33 is the v1.33 tag of the project's git tree. It emulates
|
|
the 68000, the Z80, the VDP, the YM2612 and the SN76489 and nothing more: the
|
|
tree holds no SH-2, no Sega CD hardware and no TMSS boot ROM.
|
|
|
|
A cartridge is opened as given, then under the roms subdirectory of the DGen
|
|
home ($HOME/.dgen), or under str_rom_path when the configuration sets one. It
|
|
is unpacked through libarchive when compressed, de-interleaved when it is an
|
|
SMD dump, and refused unless "SEGA" stands at offset 0x100.

|
|
|
|
The only other files read are dgenrc, save states, battery RAM and demos,
|
|
all written by the emulator itself under the DGen home.

Nothing to obtain. No BIOS or firmware is opened. The RetroPie scriptmodule
|
|
help asks for bios_CD_U.bin, bios_CD_E.bin and bios_CD_J.bin, but no code
|
|
path of this release names them, and a Sega CD image is refused by the
|
|
"SEGA" header test.
