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.
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
o 512x512 pixel character background
o 256 characters, each with independent 4 color palette
o pixel-smooth X-Y wraparound scroll
* foreground graphics
o each sprite is 16x16 pixels with per-pixel transparency
o each sprite can use 256, 16 or 4 colors
o four-way rotate and flip
o 96 sprites per scan-line, 1536 texels per line
o pixel-perfect sprite collision detection
* audio output is a stereo 12-bit frequency synthesizer
* 16 independent voices 10-4000 Hz
* per-voice sine wave or white noise
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.
