I'm making a demo (demoscene) for my beloved 5200. It is not the fastest machine and there is no 320x240 mode, so one must upscale in software which steals quite a bit of cycles.
The Apple TV Tuner Card is 320x240 and it up-scales to 640x480 (in hardware, I'm quite sure). Perhaps there is someone hardcore here that has some insights how that works?
A while ago, I tried to systematically write to all locations in VRAM (1MB, I could not reach the very first 32 bytes if I recall correctly but the rest I could write) while I had the Apple Video Application running, I had kind of hoped I would miraclously see that I could overwrite the video signal and get free 2x scaling but no, I did not get that.
Very curious if anyone has some insights on how the Apple TV Tuner Card gets its data to the screen upscaled.
