No.07177 phantomdj Tester Feb 8, 2011, 23:44	I have analzyed the game's code and this behavoiur seems intentional. The interrupt routine normally collects the inputs, which includes the coin switches. However, during the black screen between players in a 2 player game, a flag is set which causes the interrupt routine to skip over the reading of the inputs and credit switches. This behaviour can easily be bypassed by setting the following breakpoint in the debugger console. With this breakpoint, you can now enter coins in this screen between players. bp 0098,A<0F,{pc=0391 ; g} I would expect an actual machine to have the same problem. This should probably be labelled as a "bug that is not a bug" [BTNB] Don Hodges
