This tool is incredible thanks so much!
I have only encountered one issue with this tool and that is each time I import badge data with this tool it deletes my custom badges from GYTB. I've imported about 816 badges with this tool and about 80 badges with GYTB so I don't think it's a limit...
Emulation is the way to go for so many reasons NES get rid of flicker by turning off the sprite per line limit. Cheats? Ken Batocera is your friend almost every console has cheats in it
