Remove Sonic Classics (Compilation) modifications from REV02

[Clownacy]

I compared Sonic Classics' version of S1 to the usual S1REV00, and I think it's safe to say there are some properties of Classics we can set apart from S2REV02. First up, Classics' S1 has no checksum code, its RAM is arranged differently, and it writes 'SEGA' to FFFFFFE4. The copy of S2 in Classics does all of this, too. I'm thinking of removing these from gameRevision 2, to get as accurate a version of S2REV02 as possible. On a similar note, ErrorTrap is different in Classics:

ErrorTrap:
bra.s ErrorTrap
nop
bra.s ErrorTrap

I don't think this was a part of S2REV02; I'm certain S3 was based on S2REV02 (it has the JmpTos removed), and it uses the old ErrorTrap. Based on that, I'm thinking of giving that one the sack as well.
