So I modded it this morning. The process is fairly painless and it looks like there are retroarch modules from the 2600 all the way up to the playstation. I've got to wonder what the point of psx and sega cd emulation is considering you only have 300 mb of space. I haven't put on any extra games yet as I'm going through the 30 included just for the hell of it. (Even though I've played and beaten most of them countless times.)
When I do I'm going to put sensible titles on there.... strictly turbo grafx, Gameboy, 7800, ect. You know, stuff that works with just a d-pad and two buttons.
Also ben heck took apart a gamepad on his show recently and as I suspected, they use the classic controller chip and just don't connect the extra buttons. So you could add a home button, but I'm not sure what the point would be with the new hacks.
I hope my controller extensions come in soon.... it sucks to play with it on my belly. It looks like I've given up on life or something.
I've got to think that if they figure out external storage and the shortage ever ends this little guy could become the go to emulation box. It has a great, skinnable, gui, it boots quickly and it is easy to add more emulators and games.
