Gameduino is a game adapter for Arduino - or anything else with an SPI interface - built as a single shield that stacks up on top of the Arduino and has plugs for a VGA monitor and stereo speakers.
This project was created by James Bowman firstname.lastname@example.org. I strongly recommand you to visit his website first as it always will contain the more recent and official information about the Gameduino: http://excamera.com/sphinx/gameduino/index.html
This github repository is maintained by Manoel Trapier email@example.com for his own project around Gameduino and by the fact there is missing a central repository with all needed file to build/hack your own Gameduino on Internet. James’ website will of course store all of thoses files, but they are stored sparses around, and could be difficult to find.
The sound and graphics are definitely old-school, but thanks to the latest FPGA technology, the sprite capabilities are a step above those in machines from the past.
video output is 400x300 pixels in 512 colors all color processed internally at 15-bit precision compatible with any standard VGA monitor (800x600 @ 72Hz) background graphics 512x512 pixel character background 256 characters, each with independent 4 color palette pixel-smooth X-Y wraparound scroll foreground graphics each sprite is 16x16 pixels with per-pixel transparency each sprite can use 256, 16 or 4 colors four-way rotate and flip 96 sprites per scan-line, 1536 texels per line pixel-perfect sprite collision detection audio output is a stereo 12-bit frequency synthesizer 64 independent voices 10-8000 Hz per-voice sine wave or white noise sample playback channel The adapter is controlled via SPI read/write operations, and looks to the CPU like a 32Kbyte RAM. (Unlike many 8-bit machines, there are no restrictions on when you can access this RAM). There is a handy reference poster showing how the whole system works, and a set of sample programs and library.
You will find here all the data I’ve collected about the original Gameduino:
Gameduino is open-source hardware (BSD license) and all its code is GPL licensed.
