works perfectly in Mess when I tried it.

You also need the roms for creativision, I can send it via email if anyone want it.

I know TBCTBC has made a vertical scroller, Photon for the Z80 computers Sord M5 and MSX but perhaps it isn't entirely trivial to rewrite the game engine in 6502 code so it'd be better to develop a new shooter. It should be possible, I will definitely try to port Photon II to CV when it is finished...

Since that panel is removable, I will create a new one and save the original. I'm purist like that, don't want to drill new holes in the original

That's great news, will definitely try it out some time.

That's nice. Those graphics tools are useful I guess, but I have my own way for creating graphics. I first use Photoshop on a PC, then I have two small programs I've written in C under Linux to convert either to characters or sprites. I haven't made any full screen graphics conversion software, like...

I saw you had posted the guide on the website.
I noticed a small typo, at one place you wrote "700139" instead of "700319".

But are there any controllers that isn't compatible or have they all the same connector?

And these carts:

I tested my Creativision for the first time today.
It works, but not all keys on the controllers.
Here's what I've got:

Too bad it isn't better than composite. One of these days I gotta try that. I got a bunch of different machines to try it on, Sord M5, a couple of MSX machines, TI99/4A, Creativision, Colecovision...
