I really like this game and speedrunning in general, and have gotten as low as an 11:36.37 in practice but have no recording hardware or software and almost no money to buy any. I play on the GBA SP. What would you recommend I do to get myself started in the speedrunning community?
Don't reset after a small mistake, be calm, take it safe, stay focused and have fun. You might even get a really good time.
Recording wise, though, just play this game on an emulator and then record. If you haven't got a screen recorder already, I would recommend OBS: https://obsproject.com/ ---------------------------------------- Never use OBS Classic. Use OBS Studio. Its way more powerful.

LiveSplit Tutorial:
Ok, so when you open up the GBA Emulator you want to go to options > emulation > untick pause when inactivate window. Now you have started running this game hope I helped also there are no viruses in any of these downloads.
EDIT: To get the roms, just type up e.g Sonic Advance 1 rom download in google.
