New Turbo version with 50% higher frame rate.
And I found a way to free up enough ROM space to add support for [hold the UP key and turn on to enter the bootloader] in both versions.
While working on the Uzebox port with the ATmega644’s larger RAM I added a vertex cache to the 3D renderer and that sped up the rendering so much I had to find a way to fit this feature on the Arduboy.
I needed to find extra RAM for the vertex cache and the only thing left to borrow from was the frame buffer so there are black bars on both sides.
I’ve updated the classic version in case someone prefers fullscreen … at the loss of 33% FPS in comparison.
Both include the bootloader UP key fix.
Or the full .zip file with the printable PDF instruction booklet (600KB) and contains the .hex file to upload using avrdude or your method of choice.
Or if you need only the instruction booklet (516KB).
