This has most likely been made before, but its not posted anywhere.

I found it awhile back. Works just like BK's clan tag creator. Just edit the 0's, so you can have all the special characters ( (R), (C), TM, any unusable euros, etc) in your profile game save name (offline home screen, and ad hoc multi.) Kinda neat, but nothing special..

#Profile Name Editor
0xFFFFFFFF 0x017CC874
0x00000000 0x00000000
0x00000004 0x00000000
0x00000008 0x00000000
0x0000000C 0x00000000
0x00000010 0x00000000

I wont give myself credit because, again, its probably been made before. If it hasnt, then I might as well give myself some credit...
