This is a f18a vdp vector demo program. Runs on colecovision/adam or phoenix system with f18a installed It works but needs refining. Here is an example of it working. https://www.youtube.com/watch?v=Zwm0V1iXFtw

It loads and runs vector code directly from video memory using the f18a on board processor rather than the z80 of the colecovision.

This was built using existing libraries comp.lib cvlib.lib getput.lib which i did not make. Credit to PkK & Newcoleco for their libraries.

This particular program was comiled using cygwyn environment with and using a custome bank switching compiler from tursi located here: https://github.com/tursilion/colecobanking
