I've noticed a few small errors in the SMS section:
Rastan-Easter egg says for unlimited lives, it should read "unlimited continues"
Space Harrier- the sound test easter egg should be listed before the "special effects" egg. the Special effects easter egg should be re written a little to describe that "7437481" isn't a password, but instead the order of sound test sounds that must be played to acess it.
R-type: What, no mention of the SMS only secret stage?!!
