Looks like todays public release of Joiplay updates(Joiplay 1.20.520 and the others) has restored renpy functionality that the previous patch broke. (Tested with other games including HPC version 2.4.9) After installing newest joiplay and running any game once and giving permission to use storage, people may have to manual copy and move the 'files' folder from the old android/data/cyou.joiplay.renpy/ to the new destination of android/data/cyou.joiplay.runtime.renpy.v8d2d1/
