Just so I'm sure, this is just to play CDRs right? Nothing at all to do with loading games from the AR memory.
Just my opinion, but the v3 saturn modchips are so easy to install...this seems more of a proof of concept than a replacement for them. That damn cart slot is easily broken I wouldn't want to keep swapping out carts...even just for the purpose of flashing the cards themselves.
But. Maybe I'm missing something?
