They made it work by not doing picture rendering on the CPU. Same as GPUs today. Still impressive though

The video hardware is dumb, runs independent of the CPU, and just scans a region of memory to send pixels to the display. All software pushing pixels otherwise. You are not wrong with the NES, C64 and other machines using a graphics chip with sprites and other hardware features to assist in various ways. But, quite a lot happened on the CPU. BTW, this game is done on a 1Mhz 6809, all software pushing pixels. https://www.youtube.com/watch?v=wAKxa5C9jHY https://www.youtube.com/watch?v=wAKxa5C9jHY (I would skip out to the middle somewhere in that video to get a sense of what is being done) On that game specifically, it's a single frame buffer. Screen divided into two halves, each drawn while the display is delivering the other to the player.
- boondaburrah 5y agoThe Fujitsu FM-7 line of 8-bit computers actually shipped with two 6809 compatible CPUs (Hitachi 6309 IIRC) and the second one just did software graphics the whole time pretending really hard to be a GPU.
- ddingus 5y agoDual 6309 chips? NICE!! I won't bother, because I've got a good retro hobby going and under control, but I want one of those. :D
