Hey,
I just registered after having watch the first 2 parts of the specs presentation videos, very cool stuff IMHO.
I talked abot the resolution issue in the comments but a forum is better for this I guess.
I understand you have concern about having anything other than the base 640x480 but let me argue with these few points:
- having zoom factor registers, one for h and one for v would allow for a lot of flexibility in term of resolutions (i.e.: setting h to 2 and v to 2 would get you 320x240) it could even be exploited for video effects I guess.
- if there's an hblank interupt (I didn't read detailed specs yet) you could set different resolutions for different parts of the screen, very useful to combined a low res play field and high res text area in a game.
- There's some very low res indy 2D games that looks awesome, one of my favorite being 2064: Read Only Memories. It's a very good looking adventure game showing of low res as an art form.
That's all I have for now but I'll complete the argument as things come to my mind. If anyone as anything to add to this I'm all hears :)
