I have hard time to make it work as the COLECOIVISON game console.

After several tries with hard learning of structure.

I could run it but, some game only.I don't know the reason why it can't play the other ROM.


First, It shows start screen by ROM BIOS.


And tested with ROM data. 

I can find upte 32KB sized ROM data but, This board ccould support up to 24KB not 32KB due to APPLE II structure.

This board also works with the privous SG-1000 joypad but not the same. Anyway internally will change this convertion to play properly.




I remember this game. 

It is very old game.. maybe when I was 11 years old, I did play it but, not good player .

In that time I didn't know what does carnival means.


It looks he is using his invented wheel. :)

It's CongoBongo..


Time pilot.. It is some similar as the arcade game..Anyway It's fun to me.


Oh my poor frog..

Maybe from that time, we have to consider to build alternate ways to avoid  the road kill.




And I'm trying to run other games but, still no idea what is the problem.

It looks memory fault or NMI fail. Anyway there is no ROM.. it means, it could be overwriten by code..

It having some hard to understand the structure of COLECOVISION...


Anyway, This VDP board isn't purpose for GAME emulator.

I'm want to show what this VDP board could do. but, It is a board for GAME play too.

Please don't forget it is a daughter board of the CP/M card. :)

And enjoy some game when you are tired while you are making your own program.


Thanks
