Summary	01768: bldyror2: Attract mode causes freezes and it also freezes occasionally during game play with "Interlace On" (Default) in Test Mode.
Description	There are at least two freezes caused during the attract mode presentation (after the logos). 1) Coining in during the presentation causes the screen to freeze, but the music to continue. 2) Waiting through the presentation causes the game to freeze at the end. This does not throw an error in GDB, and does not prevent a reset (including soft resets). Coining in during the logo works fine, and the game otherwise plays without freezes as far as I've played. Tested with self-build and with unofficial u5 binary linked to by MAME Testers, same results. Update: The game also freezes occasionally during game play.
Steps To Reproduce	Type 1: Coin in during the attract presentation. Type 2: Wait through the attract presentation.
Additional Information	I was hesitant to list this issue, considering the game has a file listed as "bad dump". The source mentions it as "OK ( bad dump? )" but doesn't list it as GAME_NOT_WORKING, so I thought it'd still be worth reporting either to see if the game issue isn't related to said bad dump (and is fixable) or whether it needs to actually be listed under GAME_NOT_WORKING due to the bad dump causing this issue (because, IIRC, the flag is there even when a critical issue unfixable for the forseeable future can be avoided?), since I don't have the coding know-how to figure this out on my own. =/ Apologies if this report is of any way "out of line", as the FAQ does not consider this sort of situation yet.

Wih the old bad dump, using "Interlace Off" would get you to the title but then freeze when the title faded out.
