I know this is an old post, but i'm trying to find information about this really rare extension, how it works ? how colecovision games work when it's plugged into Pencil II ?
In fact, everything that could make pencil II a little more attractive and fun
Is there any dump that exist somewhere ? or even some work that could explain what is it ?
I know that this extension is only a rom with some code inside. Nothing more, as seen on a picture showing it completely opened
I'm trying to figure out how bios call some magical code and convert a colecovision game into a pencil II game, but without more knowledge it's .... difficult.
Thanks a lot.
