Hi Guyz! I've recently upgraded from 2.71 SE-C to 3.03 OE-C by Dark Alex! I Follow all the instruction and walah! i did have 3.03 OE-C! But i do have problem in some .CSO games (Fight Night Round 3, GTA LCS, NBA Live 2007) it do loads up but after asking me about autosave it hangs up / freeze and i have to removed the battery (is it ok to removed the battery?) or i will wait forever. But the other .CSO games (Dragon ball, Miami Vice) works fine. Can anyone help me on this? Config. Skip SCE logo - enable hide corrupt - enable game folder homebrew - 3.03 kernel autorun - disabled use no-umd - enabled fake region - disabled free UmD- enabled. Do i really need UMD to run other .cso games? if yes why can i play miami vice & dragonball even if i don't have any UMD? Thanks!
