I have a GBP and I was wondering if I could run this game on it for ease of streaming. I tried looking around but no one ever mentions using one.

Just about everyone who records a console setup records from a gameboy player. You can definitely use one.

Almost every GBA speedrunner, no matter which GBA game, when they run it on console run it on a gameboy player. Some people run on a DS capture but those cases are rare.

Ok thanks! Now I will definitely start speedrunning/streaming this game!
