How does this compare to the SNES version? Is the route about the same? Do all the same skips work?

I’m learning LTTP on SNES and it would be kind of cool to practice on my gameboy when I’m at work on breaks and stuff

Any% No Major Glitches on GBA has the same routing for the most part. The difference is that enemy AI is a little bit different and because the GBA screen is smaller than the SNES screen, room strategies are going to be a little bit different. The biggest difference in GBA NMG is that you pick up gold sword and silver arrows because tempered sword strats for Ganon is not faster in this version.
