Bootloader
From Gamebuino Wiki
For now, Gamebuino uses the Arduino UNO bootloader. It works great, but you need a computer every time you want to load a new game. With hybrid USB/SD card bootloader, you could switch between games just by restarting your Gamebuino !
That's why I need YOU, a bad-ass developer, to make it work. A guy already did that, but I didn't manage to compile the source yet.
- Arduino bootloader: for the ones who don't know what a bootloader is
- 2boots, a SD-enabled bootloader source code
- 2boots variant, a tweaked version that is supposed to be compilable
My goal is first to compile and get it to work, obviously. Then, it has to be slightly modified to be easily usable on a Gamebuino. Here is how I picture it:
- The SD card contains a program named "LOADER" which is loaded when the Gamebuino is turned on while pressing "C". This program allow you to navigate in the SD card and select a game. Then, it writes the game file's name in the EEPROM
- Turn the Gamebuino off then back on
- The boot-loader loads the game selected by reading its name in the EEPROM
All the EEPROM part is already included in 2boots, you just have to compile it and add the C button feature.
Good luck !
