Changes for this version 1.2.0:
I think all emulators are now supported.

Changes for this version 1.1:
Changed the main mirroring swap to a new default location $EBFC
and moved the MMC5 Setup to a new location at $3FF10 so people can use
that free space at $1EBB0. Forgot to add PRG/CHR swapping with MMC5 equivalents to JSR's.
