The byte in the supplied nvram at 0x110 needs to be changed to 0. This gets the game going. After that, only 7 works as a credit key. I suppose a developer will need to find out why 5 and 6 don't work. There's also bad flickering in the HOLD CARDS AND PRESS START message.

No.24244 Robbbert Moderator 3 hours ago	I found that by using the 2nd half of the rom the game runs fine - but only one time. The next time it is started, the inputs don't work, and it plays an endless tune. So in order to use it, you need to delete the nvram each time.
