Alright.. at the early stages of bringing my aussie '720' to life. Game boots fine. No graphical or sound issues. However, Joystick did not register at all under test. No skater movement.
Replaced the LETA chip on my board today and WOO HOO .. some skater movement & joystick registers ..... somewhat. During the calibration set-up stage, 3/4 of the square register boxes come up, except for a group of them in the lower right corner (see pics). I then need to spin the joystick around again and another 2 register. Spin it again and another 2 register, Spin it again and the last 1 or 2 register!!???? Bizarre.
My voltages are fine at the CPU board, running the joystick test with +5 adjusted from 5.0v upto 5.18v at the board and Joystick opto coupler board. The Coupler board is new from Ram Controls. Threw in the old opto board... and it worked with the same problem.
Maybe a dodgy LETA chip off my spare board?? The board looked slightly hammered, with mulitple bent header pins.
Have heard of random squares not registering, but no the same area. Also occasionally, one square will register in a different area to where the joy is pointing.. but I think this happened when the +5 was just under or on 5v at the Coupler board ... which I know can cause issues if it's slightly low.
Anyone ... Bueller??
