Original game and rom for emulator has some parts where you will face lag. I guess repro cart is ok if it has these similar issues. If it doesn't, you could save couple of seconds during your run.

I wish Prince_Leaf would notice your message. He could know better than I.

Oh, and welcome! This game sure needs more speedrunners around it and I'd be happy to see if someone was to challenge me and Prince_Leaf. This game is so much fun and it deserves to get more attention.
