'''Forum Thread:''' [http://www.aussiearcade.com.au/showthread.php/42164-Moon-Patrol-Repair Moon Patrol (Bootleg) PCB Repair] 
 
'''Problem:''' Garbled foreground graphics, text and title screen. Turning voltage right down would bring most of it back. 
 
 
[[File:Pcb repair moon patrol bootleg 1.jpg]]
 
 

'''Fix:''' The background, text and scrolling is handled by the bottom pcb marked MP-712D. Using the Schematics and a Scope I traced the problem back to a pair of 74ls173's @ 1D and 1E. 

'''Problem:''' No sync 
'''Fix:''' dead 74ls139 @ 2C on the CPU board MP-712B 
 
'''Problem:''' No sound. 
'''Fix: '''missing 1000uf 16v cap C21 and 3.579545 mhz crystal. 
 
16/03/08
 
'''Problem:''' white blocks over moving sprites with horizontal lines through them.

'''Fix:''' Dead output of a 74ls08 @ 4D See pic 2

===Board 2 (Blue bootleg)=== 
Problem:''' Background layer is missing other than a green at the top and the red bottom layer. Layers do not move: game resets randomly. 
 
 
[[File:Pcb repair moon patrol bootleg 2 1.jpg]]
 
 
'''Fix:''' Dead 74ls08 on the board labelled MP-712D which outputs all the background paralax scrolling data. Only pins 11, 12 and 13 get used 11 being the output. Fugitsu naturally 
 
===Board 3 (Green Bootleg)=== 
Using good working set above I went through each layer and fix them. 
(MP-712B)(CPU) 
'''Problem: ''' Dead board, no clock on pin 6 of Z80 
Fix. Output stuck high on 7417 @ L6 pin 12 
Pic 4 and pic 5 show working input and output(inverted) on scope. 
'''Problem:''' Blocky Graphics, program seems to be running but will crash after awhile.

'''Fix:''' Pin 15 stuck high on the bus transceiver 74ls245 @ 5m (Fujitsu) 
Board now runs. 
(MP-712C) 
'''Problem:''' Character Sprites in wrong positions, buggy all the way to the right. 
 
 
[[File:Pcb repair moon patrol bootleg 3 2.jpg]]
 
 

'''Fix:''' Dead output on 74ls139 pin 12 (Fujitsu) All other out puts stuck high. 
 
'''Problem:''' 5 out of the 6 enemy ships missing from top of screen in demo but you can still see the enemy firing. Other symptoms: Buggy splits apart(half buggy at bottom of screen) when jumping rocks when going up hill, as board warms up some sprites are split apart.

'''Fix:''' Bad 2114 ram @ K7 
Other notes. 
I must have raided this board at some point for the 32 and 256 bit proms @ 1F and 2H and a AY3-8910 on the sound board. All missing parts replaced with new ones.
The high score save mod is based on the williams set so I reprogrammed my blue board to suit. Just a matter of reprogramming 6 roms and 1 prom.

And of course this is how all Moon Patrol's should look
