The Terminator
It will still work but the title screen is not working right.

Use Delta Patcher to patch the ROM. Ignore the checksum and then patch the file.

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.
