Making a custom ROM header in GBAFEs

This is largely a very useless change, but I thought I'd post it here since it's a good little bit of fun.

You can actually customise your ROM header, which is always at 0xA0 in GBAFE ROMs. You get up to 12 characters for the ROM name, followed by 4 characters for the game code. A 0x00 will tell the game to stop reading for the name if you want it to be less than 12 characters. This is of absolutely no actual function, but it's some fun that you can do to customise your ROM and make it your own. Some emulators will occasionally have things like "Load ROM: AE7E" but might now say "Load ROM: AGRO" instead. Fun! Just keep in mind that some hacking programs like Sappy do depend on the game code being consistent, so if you get any issues with certain programs you can always change it back very easily.

Title IDs uses a pattern of CXXY(ZZ).

C : Console code -> A & B for GBA | G & P for gamecube | R & S for Wii | W for Wiiware | N for Nintendo 64... etc.

XX : Actual game ID.

Y : Region/Country Code. (E = English/USA : 45 in hex | P = PAL : 50 in hex | J = Japanese : 4a in hex | A = All regions : 41 in hex)

ZZ : Publisher ID. (Nintendo uses 01)
