Summary	05718: a2600p: The demo "TOM/JONES by trilobit" is not working properly.
Description	Unfortunately, almost 90% of the demo does not work properly in MESS a2600p system! :( http://www.pouet.net/prod.php?which=31535 Note: On pouet is said that PAL Atari 2600 is recommended.
Steps To Reproduce	Compare with yt-video: (On pouet it is said: "Recorded from a real Atari 2600.")
Additional Information	AFAIK, the only emu that runs it properly is Stella.

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.

No.11066 demotester Tester Oct 14, 2014, 19:59	Yeah, now testing the demo in an older unofficial messui 0143u3b a2600p system ... it seems to work w/o problem. :-)
