As for Mini Compressor, I'm no developer, but despite throwing almost every profile at it (including mxx and various other settings) using a clean, latest-version installation, it simply chokes on the PS3 ISO Afrika (BLUS30399). The extraction failure is always predictable rather than random—depending on the settings used, it breaks at specific offsets, which suggests something underlying in Mini Compressor's toolchain or packaging just doesn't agree with that specific image format.
If anyone has insights into mapping these toolchains into a clean PowerShell batch loop for subfolders, I'd love to hear how you set it up!
Thank you kj911 for your suggestions, I have taken on what you said, and although helpful in my approach in this area, regarding this ISO nothing you suggested worked. But he same ISO went though Diskspan 2 fine. I was hoping i could understand the deep mechanics of the profiles, the ARC.ini and FA.ini and the diskspan2 counterpart also, I tried some things trying to understand and match profiles and it's settings from Diskspan2 to Mini Compressor. However in many ways the two system are quite different to one another, and my very limited skills soon started to be an issue, and i got repeated failed execution from the FA.bat I was running.

First off — I’m glad DiskSpan 2 is working smoothly for you! That’s honestly the most important thing: your files get compressed properly and extract without trouble.
About the PS3 ISO Afrika (BLUS30399) — thank you for reporting this so specifically! The fact it fails at consistent offsets tells me it’s not random — something in how Mini Compressor handles that exact ISO structure doesn’t agree with it. I don’t have that ISO to test myself, so this is really valuable info. I’ll keep this in mind and dig into the toolchain when I can.
I totally get your goal too — wanting to understand how the profiles, .ini files, and pipelines work so you can build your own PowerShell/batch system! That’s such a great learning path.
Quick honest note: Mini Compressor is built on FreeArc with a very specific, custom layered setup I’ve put together over time — it’s not just plain FA.bat. That’s why translating settings one-to-one between DiskSpan 2 and MC is tricky — they’re built differently under the hood, different tools, different flow. Trying to match them directly will hit walls because they’re not the same design.
Don’t worry about not getting FA.bat or the profiles right away — these systems are complex by design, and everyone struggles with them at first! You’re already doing great by digging in this deep.
