Recalbox builds seven board images with different emulators. The new target scraper reads each board's defconfig against the package every system.ini core names. The names that reached no profile are mapped to the projects Recalbox builds or profiled from their source, and the mupen64plus video plugins are set aside.

"""Scraper for Recalbox per-board emulator availability.
|
|
|
|
Sources (recalbox/recalbox on GitLab, at the tag platforms/recalbox.yml names):
|
|
- configs/recalbox-<board>_defconfig -- the Buildroot packages each image
|
|
enables, one `BR2_PACKAGE_<NAME>=y` line per emulator package
|
|
- package/recalbox-romfs2/systems/<system>/system.ini -- the cores of each
|
|
system, each `[core.N]` naming the package that builds it, with board
|
|
overrides (`package.<board>`, `[core.N.<board>]`)
|
|
|
|
Recalbox runs on Raspberry Pi 3 to 5, two handhelds and x86_64: without a
|
|
target list, a Pi 3 pack carried the firmware of emulators only x86_64 builds.
