@georgebsocial I'm positively surprised how well a C64 can replicate this picture!

@CptSparky360 @FlightDreamz @MuseumCommodore No, I have a bunch of my own projects to work on. This patch was really just a side-effect of me studying SCR for some other reason. And it was only possible to do because Crammond built it with some support to adjust the time step, presumably for the 16-bit ports.

@CptSparky360 @FlightDreamz @MuseumCommodore You need to play the correct version: csdb.dk/release/index.…

@cliffski When a wave dies off, you can just reset the corresponding bit in every object and allocate it to a new wave.

@cliffski For each object, keep a bitmask of shockwaves already handled, and another one that stores whether the object was inside or outside the wave's radius on the previous frame. Then just loop, compare squared distances and set bits. Parallelise over waves, multithread over objects.

@MechaBarbarian @SkaldRpg All the charm is in the originals! It looks like this style works very naturally with the NUFLI limitations (roughly 3 colours per 8x2 pixel blocks), probably because it doesn't use too many very different colours in small areas.

Finally got around to writing a long article about the #AppleII port of Stunt Car Racer, including a tutorial on how graphics works on this platform: cobbpg.github.io/articles/stunt…

@Shaun8ebbington @Indie_RetroNEWS @RetroGamingRVG @TheRetroAsylum @ClassicReplay @pixeladdict_mag It had six-bit ASCII. Lowercase is too much luxury for thousands of dollars. 😉

@Shaun8ebbington @Indie_RetroNEWS @RetroGamingRVG @TheRetroAsylum @ClassicReplay @pixeladdict_mag Which is exactly what makes it a fun and interesting challenge to code for! 😉 For its time, it was much more advanced than its peers, and if anything, I have even more respect for Woz after getting to know his creation a little more.

Against my better judgement I decided to port the #C64 version of Stunt Car Racer to the original #AppleII. To my surprise, it actually worked out pretty well, but it was a really tight fit for 48K. Download link under the video. youtube.com/watch?v=N2uZCS…

@rwxdesigns Interesting question! The Oric would be the most straightforward, being a 6502 machine. The graphics could look like on the Spectrum. I guess a VIC-20 port is also possible with RAM+ROM hybrid cartridge (probably not something that existed back in the day).

@markmoxon @khconnell @TheFatSlags Basically he was refining his techniques throughout the 80s, and it was more about building up knowledge than reusing code. For instance, one of the ideas that made SCR efficient was the fisheye projection that he invented for the Sentinel, I believe.

I wrote an article about converting Stunt Car Racer from the C64 to the Plus/4 for those interested in the technical details: cobbpg.github.io/articles/stunt…
