260-byte Megadrive demo
Posted: Sat Aug 08, 2009 1:14 pm
Inspired by that thread and snkenjoi's ROM, I decided to write a quick demo. It's a bit of an experiment.
ROM here
Source Code here (GNU asm)
It's nothing pretty. I just wanted to see how much I could do within the size limit (using the vdp). I didn't use a lot of dirty tricks, only a few.
Code: Select all

* What's it do?
* -------------
* - passes TMSS check (should run on original hardware)
* - sets up the vdp (registers, VRAM, CRAM [2 colors])
* - uses 1 scroll plane (no sprites)
* - uses full-screen scrolling
* - reads gamepad on port A (use D-PAD to scroll)
* - uses a small amount of work RAM (scroll coordinates)
* - not much
