YoYo Loader is a loader for libyoyo.so, the official GameMaker Studio Runner application for Android, for the PS Vita.
YoYo Loader works by loading such ARMv7 executable in memory, resolving its imports with native functions and patching it in order to properly run.
By doing so, it's basically as if we emulate a minimalist Android environment in which we run natively the executable as is.
This enables to run potentially any game made with GameMaker Studio.
Installation
Requirements:
- libshacccg.suprx.
- kubridge.skprx.
- fd_fix.skprx OR repatch_ex.skprx.
- Game Data Files: Android OR PC/Console Bytecode.
Install kubridge and FdFix by copying kubridge.skprx and fd_fix.skprx to your taiHEN plugins folder and adding two entries to your config.txt under *KERNEL (change to ur0:tai if you store the plugins there):
*KERNEL ux0:tai/kubridge.skprx ux0:tai/fd_fix.skprx
(Note: Don't install fd_fix.skprx if you're using rePatch plugin.)
Install libshacccg.suprx, if you don't have it already, by following this guide.
Games must be placed inside ux0:data/gms/GAMENAME, where GAMENAME must refer to the name of the game, in form of an apk file renamed as game.apk. You can get all the required files directly from your phone.
Inside the loader, you can also find a feature, by pressing Triangle in the game selector screen, to optimize the apk. Such feature will optimize compression of the files inside the apk to not cause stuttering and loading issues and will also remove any unnecessary file thus reducing the final apk size (see tutorial and comparisons).
User guide
What is supported:
| Type of game | Compatibility |
|---|---|
| Android Bytecode | Native |
| Android YYC | Native |
| PC/Console Bytecode | Yes |
| PC/Console YYC | No |
For PC/Console exported games, you will need to perform an assets swap with a blank Android exported project with a Game Maker Studio version similar or equal of the one of the game you want to attempt to run. You can find a small guide on how to perform an Asset Swap here.
Note that patches to the bytecode may still be required in order to fix resolution, inputs or performances issues. Any game reported as Native, instead, will work with simple drag'n'drop of the apk.
A comprehensive Compatibility List can be found here. You can contribute to it by opening an Issue here.
If a game seems to be running out of memory, you can try to fix this issue by externalizing its assets with the related built-in function in the Game Selector. It is also possible to squeeze even more available mem by manually compressing externalized textures in PVRTC2 format (A guide can be found here).
