for some reason the practice rom works on multiple rom racks but for among us bros it always says: 😭 Found MMC3, assuming a GreatEd hack and let's hope it works out. 😊 Level banking RAM appears to be at 07fb. and it won't work when I open it

I just got Nestopia and I have a question about the hotkeys. Resetting the rom as an example is mapped to a specific key on the keyboard. I am curious as to whether you can map the hotkeys according to your preference. On FCEUX (the emulator I usually use) you can map the hotkeys to whatever you want, so I'm already comfortable using the buttons I usually use and I definitely won't play much on NestopiaUE if it isn't an option.
