I lied. It's not so much cannibalizing a unit so much as cannibalizing the fact the after-market for replacement parts seems to have given lots of below $20 options on things like batteries, screens, and such.
Thought: The DSiXL's touch screen looks about the right size to slide over as an on-case io/display option. I'd like to figure out if there's a way to have that display working through the GPIO thing. I do not know if this is possible but I'd like to leave the USB ports alone and I'd like to be able to still plug in hdmi/composite and have that act as a primary display (with on-case screen acting as either information display or a set of inputs you can use without a remote.
Thought: How hard would it be to use a DS's battery and have it chargeable without causing things to go kaboom? If it can power a DS for six or so hours maybe it'd be a good solution for this thing.
I'm the first one to admit I'm not qualified to do the figuring here. Barking up the wrong tree or this seem viable (albeit difficult)?
