Cogitare computing

For "C64Month" (August on twitter) 2020 I decided to try to make a SNES MODE7 engine for the old commodore.

For some reason I actually started off believing I could potentially pull it off in bitmap mode.
After spending way too long on that I ended up aiming for something a bit more realistic.

Using 4x4 pixels FLI mode I get the benefit of being able to use all 16 colours anywhere and both faster and less plotting than in bitmap mode..
Not quite as impressive as bitmap mode, but ok I guess...

A bit after the end of August I had it up and running. It's a bit choppy, but I think that with a bit more work and a "progressive picture updater" might get it fast enough to be playable.. But that will have to be for C64Month some other year ;-)

For C64 Month 2022 I decided to revisit my attempt to make something similar to a "Mode 7" racer
The new version still has some optimizations that need to be done, but it's already faster and has support for larger maps.
If you notice that the engine seems to run faster after the kart passes the "Hello twitter!"
message it's because I dynamically switch over from 4x4 FLI to 4x8 and then back again after passing the Commodore logo.
