Hello!

Long story short.

Anyone see an issue using an IPS V3 for recording runs? It allows GBA to have a component out, to allow play on TV.

Are hardware mods like this a concern? Is this a viable way to record without utilizing a Gamecube/Player?

Welcome to the site. You’re likely going to need to ask this question in the forum(s) for the specific game(s) you’re interested in running, as there are no site-wide rules on this sort of thing.
