Nope, I never used it before.Have you tried other file extraction app I’ve been using RARLab ever since I started emulating games on mobile since mid 2010s
I never used pbp format before.See if you can compress your games by keeping them zipped (prolly not)
Or else see if it supports .pbp format.
Thank you for showing it, even when these options are not good.I don't think there are any good options on mobile.
There's this web browser app but it has two problems. First, it takes a long time to convert files (maybe 10 minutes for a PS1 disc). Second, the CHD it creates works but fails verification (the checksum it says it should have is different than what it actually is).
There's also an Android app but it's labeled as heavily WIP and hasn't been updated in 7 months so it's using an outdated version of chdman.
