I have a PSP with 3.40 OE-A FW and the problem is that the PS1 games aren't running, the screen goes blank after the Sony Warning/Disclaimer (before the Playstation logo) and thats it.(have to press home to exit). I made the PS1 eboots and keys file by making the ISOs using MagicISO, then used the psx2psp .71 to make the eboots (the eboots and keys file are in their proper place). I've tried FF7 disc 1 (NTSC), FF9 disc 1 and Vagrant Story, but none worked. And its not a problem with the firmware was PSP ISO's and PS1's Ace Combat 2 and Bomberman (from torrents) work perfectly fine. So any clues whats wrong?
