My (non submitted) entry for the Vintage Computing Christmas Challenge 2022. I didn't submit this because to me this was more a personal challenge than a competition. I am quite happy with my results.
I coded an initial naive version (114 bytes) and then set my goal to getting something shorter than 100 bytes. After 5 more versions I ended with a 70 bytes .com file. Not that bad for this dinocoder! ;)
Just after watching the VCCC 2022 Results video I felt like I could save some more bytes by refactoring my last version (v6) to draw triangles instead of quadrilaterals and that is how I got to my final 50 bytes version.
| version | executable size |
|---|---|
| v1 | 114 bytes |
| v2 | 111 bytes |
| v3 | 100 bytes |
| v4 | 97 bytes |
| v5 | 83 bytes |
| v6 | 70 bytes |
| v7 | 50 bytes |
You can assemble each version by leaving the corresponding line uncommented in the vccc2022.asm file.
