MAMEWorld Forums - EmuChat - Re: Is Pong more accurate in MAME or DICE (or is it a tie)?

As for MAME, .153 version, running Pong (personally using 32 bit build version), makes up for the miss in .152 version.

With .153 version, there is a visual flaw when Pong is in attract mode. Whenever the pong/ball hits left side or right side of playfield, there appears to be a horizontal scanline visual effect that flashes on screen and then disappears after pong/ball bounces off of either left side or right side of playfield. Other than that, Pong plays fine imo.

I mentioned it in another post, but Pong Doubles is also supported. In src/mame/drivers/pong.c, is the part that has a portion of Pong Doubles and it refers to Pong Doubles netlist code that is in the tdice.c file for time being. Whether it gets updated and moved around later in future MAME updates is another matter.
