Applying to ROM tends to not work though as it's read-only on most cores and technically if you poke the currently loaded bank it doesn't propagate (I think) In the context of emulation, you always have the full ROM available to patch so you just need to resolve what bank it wants and do a bit of math if you're applying to the ROM domain. To solve this, they added bank-switching codes so it'd only apply if the proper memory bank was loaded. This was clearly bad for the gameshark because you could have multiple values at the same address depending on the game context. You mapped rom banks which'd all be accessed through the same address. On the actual Gameboy, you didn't have the full ROM mapped at once with most mappers. This is an bit of an emulation vs real hardware issue.
