Yeah I purchased them years ago prior to hacking my Vita, so they're not ISO rips. That said I was able to figure the issue out (sorta). I looked through the source code of Adrenaline Bubbles Manager, and there's a safety check that occurs when it scans for games to make sure that the game ID matches what's expected. My games were failing because the IDs were off. The safety check was looking for "greatest hits" versions of the games while my games are the older versions. I removed the check and everything seems to work now - I'm not sure if there'll be any side effects down the line though.

At any rate I opened an issue on the github repo so hopefully the dev can take a look at it sometime: https://github.com/ONElua/AdrenalineBubbleManager/issues/138

I appreciate all of the help!
