sanik had source for it on his site i gave it a tweak so u can close the menu
http://www.megaupload.com/?d=M5I8PIQZ
its only a cheater does not actually enable codes but you can see his new setting tooltips when u press triangle on a code it gives u a small menu on the cheater page with options:
edit cheat
rename cheat
duplicate cheat
shift cheat down
shift cheat up
delete cheat
save cheats
re load cheats
also i noticed a readout if u have any codes that are
#code
0x00000000 0x00000000
it will give it a label of [Bad Code]
nothn too cool but its only part of revL and has some bugs maybe he already fixed them maybe not
