Sprite and map scrolling demo on CoCo 3

This is a demo I did on the CoCo 3 that features:
- Fullscreen, smooth scrolling background
- Up to 8 sprites, 16×16 pixels, with transparency
- Very large background map: 5440 pixels wide by 192 pixels
- 60 frames per second
- Multiple animated background tiles
- Runs on a stock CoCo 3 with 128KB

The CoCo 3 virtual disk can be downloaded here to try on emulator or on your real CoCo 3:

This looks awesome. Any plans to make a game out of it? (I'm also curious about the scrolling - how many pixels wide is the scroll stepping?)

Thanks! No such plan yet, it's just a tech demo. The scrolling is 4 pixels per frame using the Horizontal Offset Register with virtual screen enabled. (btw how's Moon Patrol doing?)

This is mind-blowing! Any plans of releasing the source code?

Holy cow! And you got SockMaster's attention. Good job!

Wow ! This is unbelievable ! Its great to see clever programming on older hardware but it is also a bit sad... I mean, I would like to have seen that in the prime of the Coco 3. But anyway keep the good work ! I sub.

I knew the Coco3 was capable but that was beyond even the NES (it seemed to me). Nice!
