My plan is to make a Wii portable in a small Toshiba portable DVD player chassis I have. Since the original screen was 480x234, the composite input on it looked like trash, and I had to upgrade. I ordered a new LCD yesterday. It's the same size (9") but is 800x480 instead, and has a VGA input on it, which I'm planning to use with the Wii native VGA mod. The DVD player has a detachable 4400mah battery, which I will upgrade in the future, since it isn't very high capacity given the size of it. I got an RVL-CPU-40 Wii off of eBay for about $15, and so far the rest of the parts (voltage regulators, LCD, 128GB Samsung USB drive, audio amp) have only been around $70. The actual DVD player was basically free, and is in great condition (though the batteries are slightly bloated, one of the other reasons why I want to replace them). I'm planning to integrate a Gamecube controller into the body of it using 3DS sliders, and a GC+ as well as rumble functionality and WiFi for Wiimmfi WFC. A question I have is whether there's a board I can get that will allow me to charge my 7.4v battery pack with a normal 12v source. The battery already has a BMS on it that I can probably reuse if I change the cells.
