I'm kind of a newb to this jailbreak thing. I recently just bought a jailbreak dongle & installed open manager V2.1H w/hermes V4B hex. Most of my games work by copying into internal hdd & running it w/ the open manager. But there a few that don't work (ie. split/sec., medal of honor, COD black ops), just a black screen when trying to run.
I've been searching everywhere to find the answer but seems like most ppl are running some other software. Can someone shed some light for me? Thank you
