Each standalone profile records where its version is read: the source at its pin (clk 2026-07-23-136-g9020107, shadps4 0.20.1 WIP, eden v0.2.0-401-g26a03d2), the APK, binary or archive read (kind package), or, where no reading can be made, kind unverified with the reason: a host the tools cannot read, a forge gone or not answering, no build recorded as read, a pin on another branch. Those keep their value, unconfirmed.

|
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.
