Ok,
Seriously, you are like, the best moderator ever. I've just come on because I was having troubles figuring out yoshihiro (that's the name in the file) for 5.03 gen-a, and you've pre-empted my question with exactly what I need.
Thank you, and keep up the good work

....just out of curiosity how do you rebuild an iso?...

EDIT: ..as i have some issues with patching/decrypting the EBOOT of GTA Chinatown Wars...and i cant find anything that tells me how to "rebuild an iso" and im getting the error of 80020001....

Using UMDGen replace the decrypted file back into the ISO in it's proper place and then click on save, it will give you 3 options choose the ISO for regular size and optimum compatibility or CSO for a smaller size file. This will rebuild the ISO.

...do i need atleast something higher than 5.00m33-6 to run the patched games?...cause both decrypted and decrypted with patch for 5.00m33 dont work...
