|Tester||mmarino4||View Status||Public||Platform||MAME (Official Binary)|
|Assigned To||Resolution||Open||OS||Windows Vista/7/8 (64-bit)|

|Summary||06667: sundance: Graphical and gameplay oddities when pressing multiple buttons simultaneously|
When pressing more than one hatch button ("pad" in MAME) the game will often open a completely different hatch or generate additional hatches around the screen. Some examples:
-Holding player one pads 8 & 9 will open player one hatch 1 instead of 8 or 9 or nothing.
-Holding player two pads 4 & 5 will APPEAR to open player one hatch 2 but player two patch 2 is actually open despite no visual indication.
-Pressing player one pads 4 & 5 will cause a bunch of lines to go across the screen with an accompanying sound. This does not appear to effect the gameplay and cannot be done on player two's controls.
These are just some examples but it is not limited to this. This also falls under the graphics category but since it can effect the gameplay, I listed it as such.
|Steps To Reproduce||Start a game, preferably two player. Press and hold different combinations of pad/hatch buttons on the same players controls and see what happens with each combination.|
|Affected Sets / Systems||sundance|

|what was the nature of the original control panel, maybe pressing the buttons together was impossible?|

|This will be tough to determine due to how rare the game is. From the look of it, it just had a pair of basic 3x3 keypads. I can't find any pictures underneath the control panel to see if there is something that could act as a mechanical restriction for the other 8 keys.|

Schematics for the Sundance control panel are available, and they show what I suspected from the report: the P1 and P2 hatch inputs are priority-encoded (which makes it impossible to register having two pressed at once). A LS147 is used for each, though the priorities don't look like what you might expect (Hatch #7 seems to have highest priority, while Hatch #3 has the lowest).
