i have a game that is in a file format called multi15 and when i install it into my psp it saids corrupted data do anyone know why is it like this?
can unpack with winrar? it can unpack, unpack the files/folders and repack using umdgen
i guess its a winrar file. u can right click on the file and click on properties and then see what format it is. if its winrar, you will have to have winrar the software installed of cos. then after that, just double click and open. then extract. thats all. the extracted file should be in ISO or CSO format in order for your psp to read. and you will have to put it into the "ISO" folder. thanks.
