Yay It worked for me
For some reason.. When i ran reactpsn2.0 with all the rap files you provided (already in my exdata folder), some games didn't work. Then i went into file manager mode to find the names of those games (like EP0082-NPEF00069.. etc) and did a manual search for those games in the exdata folder you provided, where i found those single .rap files and then made a new exdata folder on my external harddrive with only those .rap in, changed the username back to 'aa', ran reactpsn2.0 again.. And the games worked!
This could could be whats happening to you denxing, i'm not sure. You must also notice that a US .rap won't work for a EU game and vice versa.
I found some more .rap files and possibly psx/psn games that isn't linked here, although i'm too lazy to check and compare whats not included xD.
If i'm not allowed to link this website, then please let me know: Removed. Definitely not allowed :P
