Summary	02642: myfairld: Black screen in Virtual Mahjong 2 MFL
Description	When you correctly set the game to 1P, and exit the setup, you get a black screen immediately after the begginning game selected screen. And it stays that way. If the game is set to 2P like it is by default, the game correctly does what it usually does (restarting the stv logo sequence). Note from Source: - myfairld: Apparently this game gives a black screen (either test mode and in-game mode),but let it wait for about 10 seconds and the game will load everything.This is because of a hellishly slow m68k sub-routine located at 54c2. Likely to not be a bug but an in-game design issue.

In the source file (stv.c), it states this for the game: - myfairld: Apparently this game gives a black screen (either test mode and in-game mode),but let it wait for about 10 seconds and the game will load everything.This is because of a hellishly slow m68k sub-routine located at 54c2. Likely to not be a bug but an in-game design issue. In my experience it's more like 30-40 seconds, but it's a definite delay before you can get to the title screen.

No.03033 Tafoid Administrator Nov 12, 2008, 20:29	To be honest, I thought it was freezing too until I spoke with Kale and discovered the Source entry referring to the game. It's ok, though, this driver has not had it's source noted bugs transferred yet. It's a slow and ponderous project the Fujix is pretty much doing alone lately.
No.06164 Kale Developer May 22, 2010, 17:47	This looks fixed now, i.e. it accesses the menus at bearable speeds (not more than 1/2 secs).
No.14061 Kale Developer Aug 2, 2017, 22:44	Reopened because it randomly happens as for 0.188 (still requires like 10 seconds from time to time)
