A Proof-of-Concept libX11 Shim for Gamemaker Games to run under Box86 with GL4ES (and the necessary set of hacks on top of it).
To actually run said GameMaker games, you'll also need the experimental versions of Box86 and GL4ES provided, and for most games, a way to remap your joystick.
As an example, this is the script I'm using to test Nuclear Throne (on 351ELEC):
#!/bin/bash
export LIBGL_ES=3
export LIBGL_FBONOALPHA=1
export LIBGL_ALPHAHACK=1
export LIBGL_FASTMATH=1
export LIBGL_GL=21
export LIBGL_FB=4
export BOX86_ALLOWMISSINGLIBS=1
export BOX86_LOG=0
export LD_LIBRARY_PATH=/roms/ports/box86/lib:/usr/lib32:/storage/axe11
export BOX86_LD_LIBRARY_PATH=/roms/ports/box86/lib:/usr/lib32/:./:lib/:lib32/:x86/:/storage/axe11
export BOX86_DYNAREC=1
~/rg351p-js2xbox &
/roms/ports/box86/box86 runner
killall -9 rg351p-js2xboxmake -j$(($(nproc)+1))
scp build/libs/* root@351elec:~/axe11/ # On 351Elec
scp build/libs/* ark@rg351p:~/axe11/ # On ArkOSMost important: Currently no support. Don't (yet) open issues if you're not contributing solutions or code.
This is a very simple, and very incomplete set of hacks, shims and stubs to run X11 Gamemaker titles on RK3326 handhelds such as the Anbernic RG351P. This isn't meant as a final solution, rather a Proof-of-Concept piece working towards a more complete solution using pure GBM.
Currently you need export BOX86_ALLOWMISSINGLIBS=1 in order to run games due to a few missing libraries. This is known and shouldn't stop you from running it. If you require any additional libraries or symbols, PRs are welcome even if just to stub a couple new functions or add a few empty libraries as long as the PR states this clearly.
X11 Error reporting is not implemented. All the return BadWindow; and similar only return such as means to have something stick out during debugging, and are not actual error handling.
SDL1.2 and 2.0 are known not to work, so this can't fix issues with Chowdren-based games such as Freedom Planet or Baba Is You. This probably won't be fixed by this in the near future. Look for alternative solutions instead.
