RetroArch can't read psn zip files

[Iamthebestintheworld222]

The RetroArch version of PPSSPP can't read zip files of isos if it tries to. It only happens with the psn/minis of games.https://github.com/user-attachments/assets/e4cc6ea5-5ebd-4300-805f-aaf31a048103

Does the standalone version of PPSSPP can open that zip?
May be it was zipped using a compression not supported by PPSSPP? as i've seen a zip file that can't be fully extracted using Windows Explorer's built-in ZIP feature before (and the zip file said to be created using WinRAR)

PPSSPP standalone doesn't actually support reading game ISO files directly from zip files either, but it does offer to extract them.

Especially for small ISOs, it would make sense to just unpack the ISO to RAM and read it from there. We'd add a "Play directly" option to the extract zip dialog on standalone, and we'd just default to reading the ISO in the case of retroarch / no-ui.

Marking as feature request. In the meantime, you can work around this by simply extracting the ISOs from your zip files and playing them.

Hmm.. that is strange, since OP said it only happened with ISOs of psn/minis of games, isn't that mean zipped ISO from dumped UMD works for him? so may be RetroArch did the extraction? (which mean not a PPSSPP issue?)

it doesn't work with RetroArch, but original PPSSPP extracts the iso.

@anr2me I'd think the same applies to any zipped ISO.

I tried using regular psp rom files, RetroArch scanned them and played them as regular roms.
