Recently I issued the third Z80 programming challenge for the ZX Spectrum:
The deadline is Monday 30th March, midday (GMT).
Target: under 125 bytes.
- The X and Y coordinates are in pixels with 0,0 at the top left.
- The sprite needs to be clipped if it goes over the screen edge.
- Sprite data can be formatted however you like within 64 bytes.
- Programs must return. The
RETinstruction is included in the size.
- So everyone has a fair chance comment with the code size not code.
- There are no prizes, just the chance to show off your coding skills.
Solutions can be emailed to email@example.com or posted here after the deadline.
