@windg said in Psp games in .chd format aren't visible in ES.:

@mitu i was thinking that .chd files are recognized by ES in general and it was independent from the emulator. I thought that was a bug.

No, the list of extensions accepted is a system parameter and not a global list. When the new PPSSPP version will be added in RetroPie, the extension list for ES's psp system will be updated accordingly.
