Canvas Croquis 2 player mode flip screen issue
#378140 - 08/13/18 04:18 PM


Just wanted to point out that the game «Canvas Croquis» flips the screen in 2 player mode even if you set the dip switch for the game to "Upright" instead of «Cocktail». I think there are other games with the same issue. I used MAME v. 0.200. If someone wants to try and confirm it...

it appears that the game only has the correct behavior when the 'flipscreen' dipswitch is active. (in that case, in upright mode, both player 1 and 2 are the same orientation)

this could just be the way the original game is designed even if it is somewhat awkward.

Robbbert actually found a clean solution for that, looks like 2 incorrect assumptions in the driver were adding up to cause this issue, but it should now be actually fixed properly
