I want to convert NFL Street vol3 in to a ISO format using UMDGEN and then converting it to CSO format. But I keep getting stuck in teh UMDGEN. I put the files PSP_GAME and the UMD_DATA in the UMDGEN. But it wont let me convert to the batch file to ISO format. I can put it in the program and thats it nothing else happens. It wont let me convert.
