thanx psychodad,

still can't get shin megami tensei persona working or naruto, still getting a blank screen, but it lets me press the home button and exit game, tried both m33 and sony drivers and tried with a umd inserted still no joy

i've only got GT, FF dissidia, and nfs shift working.

so is the problem because i'm using 5.50GEN-B2 ??

or is it UMDGen compressing or deleting dummy's from the file when i save ? because the original ISO for naruto is 735mb when i extract and add the new E.BOOT its still 735mb but when i click save uncompressed ISO it turns out 589mb ?? and loads to a black screen

and i've tried different settings on UMDGen and also imported the file list with no joy

i'm downloading an already patched ISO to see if that works and guess what?? its 735mb lol

mission accomplished finally saved and it came out as 735mb and works

ok what i did incase anyone has this problem

in UMDGen i changed the option to "use standard umd padding"

then opened the ISO and exported the file list

instead of extracting the ISO is just drag and drop the patched ISO into the SYSDIR folder replacing the original,
then i imported the file list and clicked yes on the pop up box then clicked save and it finally saved it as 735mb

earlier when i wasn't extracting the ISO and doing it this way i wasn't exporting/importing the file list and it wouldn't work

and also when i had extracted the ISO and imported the file list and clicked yes for some strange reason when i saved it it would turn out as a 7gb ISO lol so i started clicking no after importing and it would turn out 589mb and not work,

so change UMDGen options to "use standard umd padding". don't extract ISO just drag and drop, export the file list, then add the patch then import file list and click yes then click on save jobs a good'n
