Yes, it does. I use jockers on Resident Evil 4 to deactivate/active freeze camera hack.harry62 wrote: I suppose the cheat device does not support D-type commands(known as jokers in most devices).
I also had to remove de D-Type code from Call of Duty 3 because it wasn't skipping the DNAS check, after removing it worked, hadn't any kind of crashes or any other issue with CoD3 and PES6 by removing the D-Type code.
MGS3:S patch made by SaveMGO has D-type code and they work with this particular 'cheat device' that I use (PS2rd Cheat Engine)....
AFAIK PS2rd only doesn't support mastercodes that don't start with '9' that's the only thing I know that is unsupported.
EDIT: PES6 randomly crashes (to reproduce this, play offline then go to the online and then try to login into account, it will probably hang in a black screen)
