I currently have a microSD card with a few cool arcade games, but I’ve rigged it so it autostarts R-Type II with mame4all directly. Seeying as microSD cards are dirtcheap, I can just have a 1-2gb microSD card for each game optimized to work on the SFP without going through emulator menus etc. and put it in a cool case with some neat artwork around it. It’ll have a real old-school HuCard vibe.
It’d be easy and pretty cheap for developers to bring their games to an attractive physical medium at a price competitive to digital only version. As a proof-of-concept this already works, as can be seen in the videos, but this is thinking more long term of course. First thing is to bring the STARFORCE PI into production.
