Imported cheatcodes which "modify" read-only domains are silently blocked

[ghost]

Its seem that any game genie, raw or pro action replay code that change something in the rom (Health, move damage , background selection, music change, etc.) are ignored by Bizhawk, but some Action Replay code such as changing character animation on the fly or simply glitch the RAM works.

I did the test with Mortal Kombat II on Bizhawk 2.2.2 (the last one that allow cheat converter for SNES). Even if I go with raw address in the latest version, changing value in the ROM doesn't seems to work.
