Again, regression in Timing/IRQ related to newer m6502 core (r18875). No need to report any more a2600 (TIA) related graphic issue - this and 05714 is more than enough to go one, I believe. I tested these too and another one called "triptych_preview" also from triolbit - all have issues after the new core. Any MESS binary before 0.147u3 will play them very accurately.

Yeah, I remember MESS playing this correctly when it first came out.

Yeah, now testing the demo in an older unofficial messui 0143u3b a2600p system ... it seems to work w/o problem. :-)
