Build Bot way more cores, not limited to 100MB etc. Can See SD Card. Just stay away from Play Store Version.

There are 3 apks
RetroArch_32.apk (32 Bit)
RetroArch_aarch64.apk (64 Bit)
RetroArch.apk (Both 32 and 64 Bit device will choose. We can choose our selves so don't use)
As I read it some cores PCSX ReARMed and Picodrive are 32 bit only. These cannot run in Android 64 bit and are not included in aarch64.apk?
So then what is RetroArch.apk? It's a different size than the other 2?
Retroarch Plus in the Playstore sucks
com.retroarch.aarch64The 64 Bit version of Retroarch requires android 8.0 or higher. Use 32 bit version for older android.To load Content I had to editandroid/data/com.retroarch.aarch64/files/retroarch.cfg in quickeditFind rgui_browser_directory="/storage/3636-3939"The Playstore version cannot set SD Cards without manual edits, etc. The Build Bot version just works.Cores have to be downloaded from within the App and are stored to a hidden private location that cannot be viewed externally. Android has this requirement for Dynamically loaded libs.
