Problem with JSO file

[coona]

I have compressed an iso into a Jso file using Danny_kay1710 ISo compressor version 1.4. It compresses the File ok . I then copy it over to my iso folder on memory card. But when i come and try and play the game on my psp the file isn't showing on my memory card even though space has been used. Just shows no game data. My psp has been modded

Like duh. OE firmware doesn't have compatibility for the JSO format. It only supports ISO and CSO. In fact, the only way to get JSO format working is in Devhook. Anyway JSO format isn't that great, so just convert it over to CSO :).
