On PAL with mechapwn ntsc originals and some dvd-r's can be launched using UlaunchELF. NTSC mechapwn allows any out-of-region originals to be launched directly from OSD.
If ps2 is deckard, region can be changed to ntsc.
I was meaning, that if 75004 converted to DTL-75004, it does recognise NTSC ps1 games, but as 50004, it doesn't boot them.
So converting to DTL-75001 is the way to go :) Boots all PS1 disks from OSD
I have the V7 console and can't boot any burned Resident Evil series game from PS1. Problem is the same on Modbo 4/5 and Mars Pro chips. Tried everything, but no luck. Where the problem can be?
