I need people to test this code. It works for me everywhere except in your house (but of course you don't need it in there anyway)

Press L+R to zoom in on your character almost anywhere
To zoom out, just open your menu and close it again
(pointer and addresses found by me)

Code:
94000130 FCFF0000
B21C2AE8 00000000
000000FC 1EEE0000
00000100 0000A000
D2000000 00000000
(extra thanks to Maniac for telling me how to use the regular AR DS codetypes for this >_<)

The only reason I posted this here is because I know other people have been wanting to make something like this, so I welcome you to test it XD
