I recently got my hands on Initial D: Street Stage, and at first I extracted the actual .iso file into 2 separate files which were the data files. Then after I learned about what I did, I merged them back together using UMDGen. I stuck it in the ISO folder and it shows up on my screen but when I boot it up(it shows the PSP game boot screen) the screen stays blank. I can still hit home and exit back to the XMB. The kernel is at 1.50 and I my fake region is disabled and Free UMD region is enabled. Is there something I did wrong here?
