I think if there is a timing issue for the Pencil II there is one for the colecovision driver as well, since they are identical, minus a few ports for the keyboard and tape.
No game on the colecovision uses rasters that way to my knowedge but surely MSX games does and its, again near exact hardware.

I know 😁
It's just a strange behavior. The code was made for rc2014. I've just tried to adapt it. Maybe something wrong with my code... Again πŸ˜…

I'll try to do some more tests with sprites this time 😏

Great job! Congrats to all involved. I will make a post on atariage. It could motivate coleconut further.

Edit: and it seems that’s done already! Let’s see what happens next.

This is some examples I adapted from others sources to learn z80 and how pencil 2 works.
Now it's time to go further and write something new 😁
Source code on github and videos on youtube

Have fun πŸ‘

Sorry to reopen that old thread, but was the dump of treasure hunter transmitted to MAME to try out in the driver?

As far as I know gameplay footage was only made on a real machine, correct? If so, I’d be curious how it runs under mame.

Yes, it was added. 'mame64 pencil2 treasure' will let you try it out.

Hello,

I will resume the discussion of this post if it is still possible.

For this pencil 2 computer, information is scarce, except that it would be a colecovision with an added keyboard and a different bios (to simplify what I found on the web).

Not having the coleco adapter, I would like to install a second coleco bios on this machine, either in a single eprom (including the two pencil bios - coleco), or by adding a second eprom connected to the machine's motherboard.
A switch switch would allow you to choose the bios before turning on the computer.

Does anyone have any advice / information for me please?
