Summary	05447: studio2 and clones: Major graphics corruption in studio2 and clones.
Description	Older versions seens to run well. I tried a lot of older versions compatible with most recent dumps, but they continue with the problem. My shot it's that the problem is related with the most recent dumps. This problem occurs with all clones, being visicon a messed green background and other clones with blue background, but all will show messed graphics. I can't say if the system freezes or it's just a graphical problem, that's why I marked major rather critical for severity. I used MESS 0.152 official build from http://mamedev.org/release.html. This problem ever occurs with any software or bios.
Steps To Reproduce	Just run the system with or without any software inserted. The graphics will be ever corrupted for all the software tested.
Additional Information	That's my first report in MAMETesters. I read the guidelines and another reports, but if there problems with my report, please notify that I will try to do better reports next time. Also, English is not my native language, and even I'm doing my better, please be comprehensible with my English errors.

No.10234 Tafoid Administrator Feb 4, 2014, 04:14	I think the proper way to handle studio2 carts is to hit reset (F3) to clear, then "q" which equates to powering the console on with the cart inserted. Any other way will not get you much of anywhere with the carts. People who know the driver better would be able to say is this is correct behavior or not - but this procedure has always worked.

No.10246 Shideravan Tester Feb 7, 2014, 12:42	Why do you have to "clear"? That's the original system behavior? Anyway, if just press "A1" (Q in default configuration) the game starts (at less is not a freeze), but the screen stay messed up... (second snap - I used same game for comparation)
No.16431 Robbbert Senior Tester May 5, 2019, 16:58	When you start the machine without a cart, you press F3 ("clear") followed by one of the letters to select various inbuilt games. For example, press A("4") for a racing game. Since 0.200, the graphics are totally broken.
