A libretro port of dmanlfc's SM2-Emu, a Sega Model 2 emulator. The port
|
|
shares dmanlfc's history up to 8b3a468 (2026-09-09) and has taken later
|
|
upstream releases by hand, up to 0.9.56.
|
|
ref: src/libretro/core.cpp:956-959
|
|
|
|
The game list is games.xml, read from <system>/sm2-emu/. The core refuses
|
|
to load any game without it. It names every set, its parent and device
|
|
sets, the chips of each region and their CRC32. The content is a MAME set
|
|
in .zip or .7z. Its chips are matched by CRC32, or by name when the ROM CRC
|
|
Verification core option is off. A clone also reads its parent beside the
|
|
content.

|
Daytona USA, its clones and Desert Tank name the model1io device set, Virtua
|
|
Cop and its clone model1io2. The device archive is looked for in
|
|
<system>/sm2-emu/ and then beside the content, and its chips win over the
|
|
copies a game set carries. A game set that holds the I/O board ROM runs
|
|
without the device archive.

|
Gun games read custom crosshair images from <system>/sm2-emu/crosshairs/,
|
|
named after the set, its parent or default, with -p1 or -p2 or without.
|
|
They are artwork the user adds, and a built-in crosshair is drawn without
|
|
them.
