Summary 09277: sws99: Random freeze in the attract mode
Description In the attract mode, this game can freeze at one of three places.

1. When the camera pans to the right, just before the demo game starts, it can freeze, with the fence sometimes twisted. Music keeps playing.

2. In the demo game, rarely a fielder catches the ball and it freezes. Only saw this once. Music keeps playing.

3. If it gets through that, then after the demo game it says "ID or NOT ID", then gets a black screen. If it gets this far, this problem always happens. No music at this point.

The fence randomly changes colour and texture, but this could be normal.
Steps To Reproduce >mame sws99

Don't touch anything, just watch what happens. You can try pressing INS to try getting the rarer freezes.

I tried bug 1 on older MAME versions (wait for scroll to end, SHIFT+F3 to hard reset if no lockup, repeat). The oldest MAME version I have locally is 0.256 and it's also broken there. I have not tried further back.

I assume it picks a random demo sequence from the RTC and/or nvram and lockups happen on specific ones, and it's not due to an uninitialized class variable.

Bug 2, I got it in-game a couple days ago, so it's not just attract mode that's suspectible to lockups.
