I was a tad skeptical when I saw the title. But it looks like you really pulled it off. It took Atari engineers like 4 years ;)
Is it fast enough for multi-input / multi-player?
Is it fast enough for multi-input / multi-player?
The only multi-input game I have right now is Tetris for 2 players. My girlfriend doesn't complaint while playing it (except when I win :P), so I'd say it's pretty responsive, even with the somewhat convoluted way the CPU communicates with the PPU and the double-buffering.
I think it will work for other types of games as well. With all the hardware, firmware for the 3 microcontrollers, bootloader software, compiler toolchain and tools, I still haven't gotten around to actually make a lot of games for it.
I can even imagine a part II with modern components after learning this level of basics.
