Yeah, sorry, it's 29 MHz. I don't remember the exact frequency. But I know that's the Prizm is clocked to 58.

Nice I understand you halved the resolution, right ? (you use 2*2 pixels)

Haha, I have to say no: it runs at 128*32 perfectly! I have just scaled up the screen is! :p

I changed a little bit the routine to use the whole screen and render modes.
THe current calculation calcs the distance. If the distance < 0, we're drawing a "ceiling", so what's new : You can choose to draw ceiling (z-inversed mode 7), floor (normal one), or both at the same time. I fixed too the horizon. The horizon parameter is the horizon's offset in the screen. At -32, it draws the horizon at the screen's middle (the both plans will converge to the horizon if you understand).


I'm designing a start of a tileset for testing tilemapping. I attached too a preview of the both plan mode. Obviously is slower at a ratio of 0.5. and the whole routine is slightly sowed down because the distance check.


EDIT : well, the project is getting quite clearer.

Awesome! As for the ceiling, to make things more realistic, if, for example, someone uses a sky background with clouds, will it be possible to make the sky scroll slower than the floor?

Nom.

I love those graphics. Will there be a background in future versions? You could make it 96x64 with an HUD on the side so that you have more room for a background by zooming the whole thing out. F-Zero or Mario Kart would definitively be great with such engine.
