Should I delete OPL's settings when using a newer OPL version, regardless if it's Beta, Stable, DB, ifcaro, DB Beta, ifcaro Beta, VARIANTS, VARIANTS Beta, DB VARIANTS and ifcaro VARIANTS (and afterwards change the settings I want)?
EDIT: I deleted GitHub's OPL Beta settings, let the latest GitHub OPL Beta version create new ones and I noticed some default settings which I didn't change in the past PS2-HOME's OPL DB Beta and GitHub's OPL Beta versions are different than before. Maybe I didn't delete the settings from the first OPL version I used (which was a PS2-HOME DB Beta one) and I've just been replacing the OPL file with the ones from more recent GitHub OPL Beta versions (first PS2-HOME's OPL DB Beta and afterwards GitHub OPL Beta ones). If so, I assume PS2-HOME's OPL DB Beta's default settings are different than GitHub's OPL DB Beta's.
It looks like PS2-HOME no longer releases OPL DB Beta versions which supported PS1 games and according to it PS2-HOME's OPL ifcaro Beta versions (right now the only OPL versions released by this site) are the same as GitHub's OPL Beta ones but oddly their (PS2-HOME's OPL DB Beta versions) current build number is lower than the latter (GitHub's OPL Beta versions) and these PS2-HOME's OPL ifcaro Beta version and GitHub's OPL Beta versions unlike PS2-HOME's OPL DB Beta ones don't support PS1 games. How can one run PS1 games on PS2-HOME's OPL ifcaro Beta and GitHub's OPL Beta versions now (I suppose with POPStarter like PS2-HOME's OPL DB Beta versions did but in that case POPStarter would have to be manually downloaded since it came integrated with PS2-HOME's OPL DB Beta versions) via SMB?
After enabling sound effects, boot sound and background music in OPL, I have a black screen when running games and after emulating a Multitap in OPL in the second controller port, the controller stops working after running games.
Does one always have to download Data when installing a new RetroArch version in the PS Vita/PS TV? If one deletes the previous Data folder and copies the new one, RetroArch's settings (like controls and aspect ratio) will be deleted.
PS Vita and PS TV hang when extracting downloaded files from the Online Updater.
What's the difference between molecularShell and VitaShell?
If I copy PS Vita's/PS TV's license folder to their microSD card do I have to refresh the license database in VitaShell?
Some DLC is still missing on the PS TV according to PKGj after copying the addcont folder. Is it possible for some DLC to not be inside this folder?
Also, what's the appmeta folder?
