I can load an UNZIPPED PSX rom by selecting the .cue file.
If I pick a .7z zipped rom, then retoarch crashes instead of unzipping it and opening the .cue. I tried .zip format and it still crashed.
Even worse, when retroarch android crashes, it just halts instead of giving a useful error message. It would be nice, for example, if the unzip folder was not writable, it gave a helpful error message instead of just crashing.
