Perhaps I do.  I have seen it on two different systems, but both are Atari Jrs.  If I recall correctly, it was certain Jrs that has problems with bus-stuffing demos, so perhaps Maggie and I are both "blessed" with these "special" TIAs.

Yeah, usually it's the 7800's and certain Jr's that have the odd TIAs.

Here's one that waits an extra cycle prior to changing the graphics for the second copy of the player 0 sprite. I have my console packed away at the moment, so it's not tested beyond Stella. Buyer beware.

[edit - removed. Used kdgarris' working score_kernel.asm fix in the main titlescreen kernel, in the first post]

Thanks.  Unfortunately, I still see the same behavior with this version.

My titlescreen gets a VERY similar character on the hundred thousand digit but I'm using a different font to, I thought it was because I didn't use DEC but might be this bug, it's not in the game only when returning to titlescreen after a game, I have a PAL light sixer.

Does the original binary I posted of the demo show the problem on your system as well? It should probably still work otherwise on your system, just with different colors.

It didn't look exactly the same but the zero was messed up in a similar way (on the right side) on my PAL light sixer to.

kdgarris provided a fixed score_kernel.asm that has timing that works on his console. I've updated the first post with titlescreen kernel 1.7, which incorporates that fix.
