Hi. This is my first time speedrunning a game ever. I have a couple questions on running any% glitchless

1. Is the game playable on gameboy sp? I have an old one that I need to find.
2. I've been looking into routes and everything seems to be with nidoking on red. Is blue playable? I haven't bought the cartridge yet and like the aestetic of blue a lot more.
3. I have a personal goal of getting a run under 2:10. Is this realistic for a casual?

Thanks and I hope to be a part of the speed running community.
