ram.asm initial commit. Replaced all address defines with labels
Value defines styled without quotes, # moved to load/store/cmp site Added registers.asm (copied from spannerisms JP disassembly) Added a bunch of length annotations Deleted old or trivial commented out code Deleted: ganonfixes.asm, map.asm, seedtag.asm Replaced obsolete credits.asm with creditsnew.asm Moved scratch space at $7F5020-3F to mirrored WRAM (7E1E70-8F) Moved clock RAM to mirrored WRAM (7E1E90-9F) dialog.asm: FreeDungeonItemNotice preserves callee-preserved scratch RAM Toast buffer moved to mirrored WRAM (7E1E0E-0F) servicerequest.asm: long store to $012E converted to word length store
