I created this thread for people to come and get updated usrcheat.dat files. In case you don't know, a cheat function was added as of firmware 1.08. usrcheat.dat files are custom cheat files that the r4 can read. Please, if you've updated your usrcheat.dat file, upload it on a file hosting site and post it here. Make sure to post what has been updated. I'll Start! http://rapidshare.com/files/26246097/usrcheat.dat.html This file contains all of the updated codejunkies AR Codes (same as default cheat.dat file) but with codes for Custom Robo, and updated MKDS codes such as online extra courses. Make sure to replace your default cheat.dat file with a blank one.
