What's the lowest sweep frequency most VGA monitors will display?
And can't the pixels be stretched to fit? That's something I've not had a chance to learn yet. On a TV, one just makes a longer pixel, and have it be a factor of the optimal number of pixels.
Can't that happen on VGA? So then, maybe it's good for 300 pixels, or so, right?
As for usability, that's a matter of what one wants the display for. Sprites are usable in low RAM situations. Tiles are too, which is how the nice text displays are done.
The idea being explored here is to present a graphical set of choices. Since the prop has software video, one can simply load what it takes to make that happen, stop it, then load something else from storage. That changes the usability game considerably, which is why I bothered with the tile display in the first place.
Baggers has a full on Raycaster running on the thing. A few tiles isn't out of the realm of what can be done. Besides, it's fun!
