A goal about emulating the GG ROM is to avoid intense CPU read checks for patching.
The Game Genie hardware does those CPU read checks for every CPU cycle.

Game Genie is not compatible with TetrisDX, btw. (At-least not the DMG/SGB version.)
You bring up an interesting point. I wonder why more games near the end of the NES era didn't have anti-Game Genie routines.
If any comparison fails, wait three minutes and change the player's name to "Cheat" (obviously,
this wouldn't work on a H*R game)
The checks could be arranged in ROM so that no three patches could take out all the checks and provide useful cheats.
All TetrisDX does is instantaneously stir-fry your battery backup into scrambled data.
