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.

notes: |
|
|
Mu emulates Palm m500, Palm m515, and (with EMU_SUPPORT_PALM_OS5)
|
|
Tungsten T3. A Palm OS ROM dump is required. The core selects the
|
|
ROM filename based on the "OS Version" core option:
|
|
Palm m500 / Palm OS 4.0 -> palmos40-en-m500.rom
|
|
Palm m515 / Palm OS 4.1 -> palmos41-en-m515.rom (default)
|
|
Tungsten T3 / Palm OS 5.2 -> palmos52-en-t3.rom
|
|
Tungsten T3 / Palm OS 6.0 -> palmos60-en-t3.rom
|
|
|
|
ROM path: RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY + "/" + osVersion + ".rom".
|
|
No hash or size validation: the code reads whatever file is present.
|
|
The bootloader is optional and ignored for Tungsten T3.
|
|
Supports no-game mode (boots Palm OS desktop from ROM without content).
