Summary	08135: qzquest: Dip switches 2-3 and 2-4 are used.
Description	Dip switches 2-3 and 2-4 are used to adjust how much time it takes for one unit of the player's timer to deplete: $00: 100 frames per unit $01: 50 frames per unit $02: 150 frames per unit $03: 200 frames per unit The table for this is at 0x1DE14 in the main ROM. This value is set when the game boots, so after changing the dip switches, the game needs to be reset for it to take effect. The RAM address for 1P's timer is 50DBF4, and 2P's timer is at 50DBF8.

No.19483 GoldS_TCRF Tester Nov 24, 2021, 21:30 edited on: Nov 24, 2021, 21:31	I'm not sure, I don't have a manual or any other kind of official documents for this game. I was able to verify the dip switches were used by looking through the game's code.
No.19487 Steve Coomber Tester Nov 25, 2021, 19:06	The DIP switches definitely behaves as you described and I would expect this would be a documented feature. I was thinking of calling the pair of DIP switches "Countdown Timer" with the following selection 1. Very Slow 2. Slow 3. Medium (default) 4. Fast
No.19488 Steve Coomber Tester Nov 25, 2021, 19:14	Do you know if the difficulty setting has any effect on the questions?

No.19491 GoldS_TCRF Tester Nov 26, 2021, 00:19 edited on: Nov 26, 2021, 00:19	The difficulty dip switches only have a single effect in the game. The game sometimes replaces one of the items in a shop or the item in the chest game with a Yes/No Slab, a 2-Choice Sword, or a 3-Choice Halberd: This is most likely on Easy and unlikely on Hardest. It has no effects on the questions asked or on the timer.
No.19496 Steve Coomber Tester Nov 26, 2021, 09:28	Thanks for the response. In the code we have a comment against the difficulty setting "??" suggesting that effect wasn't known at the time the game was added to MAME. What you advise does affect the difficulty by offering fewer or greater 'lifelines' (as it's called in Who Wants to be a Millionaire!). It might be worth updating the comment to clarify this effect.
