260-byte Megadrive demo

[TascoDLX]

Inspired by that thread and snkenjoi's ROM, I decided to write a quick demo. It's a bit of an experiment.

Code: Select all

*
* TascoDLX 260-byte MegaDrive demo
* 
* August 7, 2009

*
* 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
*

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.

I like how you still have room left for some padding :)
