The cores gambatte, genesis_plus_gx, mednafen_pce_fast, mednafen_wswan, snes9x2010 stopped working with the roms zipped in wiiflow, when entering the game, it starts and already crashes, you have to turn the video game off and on again
The cores are not automatically recognizing the classic controller

Start by reproducing the listed failures in version 1.9.0, separating the affected cores and behaviors: startup crashes, slow performance, graphical bugs, Wiiflow plugin failures, zipped ROM failures, and controller recognition. The issue names no source files, tests, or entry points, and completion would require resolving or narrowing this broad set of reports.
