WARNING: DO NOT UPGRADE your TI-83 Premium CE or TI-84 Plus CE to OS 5.5.1 and higher. It removes all compatibility with most games and removes ASM/C programming! DOWNGRADING IS IMPOSSIBLE. BE WARNED! Likewise, do NOT update your TI-Nspire CX past OS 4.5.0, else using Ndless and ASM/C programs will be impossible.

I really want to figure out how to make such game properly now (eg not the TI-BASIC way like I did in 2002 and 2007). I'm fairly sure that the HP Prime could pull it off. Otherwise I could use Mac Bernick's  engine from Trailblazer. I'm glad that PICO-8 is able to pull this off, though.

If you have PICO-8 you could download the cart and look at the code. Even if you don't, I'm pretty sure there are some tools to extract data from a PICO-8 cart.

Yeah that's what I might do. Otherwise, if Juju still has his tool then I could use that instead. Of course it depends how much I could understand Lua, though, since I am more fluent in HP PPL and TI-84+ BASIC.


ceci n'est pas une signature

By the way, the road at the bottom seems to be made with rectangles. I'm wondering if a similar technique of drawing objects could be used on-calc... (eg the CE and Nspire CX or even HP Prime) with less details. I don't know how maps would be done, though. Maybe it could just be cubic buildings for the most part.


i dont klnow how fast the CE is at rectangle drawing, but if its fast enough i think this might be possible to make :o

ICE language can draw about 4500 sprites per second. If rectangle drawing is at the same speed then that gives an idea of what performance you would get, but of course it depends how much processing is required to calculate the 3D perspective and stuff. Hence why I think it should be limited to rectangular buildings like that one Star Fox demo in 84+ ASM a few years ago.


well everything seems to be made up of these rectangles. Also, since the camera can only look in one direction i think the matrix calculations
normally used can be optimized by skipping a few entries (i mean, there is no rotation and such so that doesnt need to be calculated)

very cool, can't wait to try this on pico8!

DJ Omnimaga

Yeah I think with much fewer rectangles, this could be feasible on a calculator. I'm just worried that creating the maps might be quite a lot of hassle lol, with so many layers of stuff XD
