|
|
gw-libretro runs Game & Watch simulators converted from MADrigal's Pascal
|
|
source code via pas2lua. Each game is a self-contained .mgw archive (bzip2
|
|
compressed tar v7) containing Lua scripts, sprites, and sound data.
|
|
|
|
retro_get_system_info (libretro.c:187-194) sets valid_extensions to "mgw",
|
|
need_fullpath to false, and block_extract to false. The core reads content
|
|
entirely from the retro_game_info buffer passed by the frontend.
|
|
|
|
retro_load_game (libretro.c:256-310) passes the content buffer to
|
|
gwrom_init() which decompresses and parses the tar archive in memory.
|
|
gwlua_create() then initializes the Lua VM from the archive entries.
|
|
|
|
The core never calls RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY, never opens
|
|
files from the filesystem, and has no firmware or BIOS dependencies.
|
|
All game data is bundled in the .mgw content files available from
|
|
libretro's buildbot (bot.libretro.com/assets/cores/HandheldElectronicGame/).
|
|
|
|
No external BIOS or firmware files are needed.
