Just started working on a breakout clone for my homebrew 6502 build. Mainly to have a go at working in Graphics II mode beyond simple demos:

The video is a little washed-out. It does look better in the flesh. Here's a screengrab from by emulator:

https://github.com/visrealm/hbc-56/raw/master/img/breakout_screenshot.png

As always, all source code (65C02 assembly) is available: https://github.com/visrealm/hbc-56/tree/master/code/6502/bre akout.

It's been thrown together quite quickly, so isn't particularly well documented yet.

Cheers
Troy

Previously, my web-based emulator ran BASIC by default and you could drag ROM images into it. I've just added support for loading server-side ROMs, so now you can try it yourself:

A couple of limitations:

1. Audio doesn't work in the web-based emulator.
2. You will need a keyboard.

It's all very BETA. #worksforme

Have at it.

Oh, I've also cleaned up the code: https://github.com/visrealm/hbc-56/tree/master/code/6502/breakout
