The first pic is the decoder ROM with the #23 pin bent which I probably didn't bend it right, but it did work. The second pic (#23 bent on this pic as well) is the setup for the last jump with the +5V using a safety pin and wire which resulted in the flipping of the entire game on screen . The third pic is the source of the +5V which I just used the switching power supply using wire and electrical tape. The fourth pic is how you explained it on your last post. I re-bent the #23 pin back to its original position and placed the wire in the #23 pin slot before resetting the entire decoder ROM. The wire was firmly set and would not come out after pulling on it. I then plugged the game back in. The last pic is what was on the screen. It is a green picture with a bunch of flickering reddish/orange lines. What now?
(*********Summary Review (Tales of a Rookie)*********)
The original problem with the game was the background colors including the cliffs, surround colors, etc. were not right. They were funky distorted. I started a journey into the unknown. A savior (saltbreeze) presented himself and is guiding me through my journey. The first attempt at trying to find out what was wrong with the game was when I jumped the #23 pin with a safety pin and wire attached to the +5V switching power supply while the game was on. I think I also touched the #22 and/or #24 pin at the same time which fried the decoder ROM and this caused a nice spark. Eeeks!!! I wasn't very careful and was doing this by hand with the game on. First mistake!!! I then replaced the decoder ROM with a new one. This resulted in the background colors and surround colors being restored, but all of the characters (buzzard riders, ostrich riders, eggs, numbers, colors, etc.) are now distorted.
I made a second attempt. I used the safety pin again, but this time was much more careful having the game off. I set the safety pin on the #23 pin and attaching it so the connection was stable and not moving and then turned the game back on. This resulted in a green colored screen only. Wrong again!!!
The next try (third time is not a charm) was when I bent the #23 pin and attached the safety pin to it as decribed above as seen in the first two pics provided in this reply. This resulted in the flipping of the images being left to right or you may say right to left. Wrongo!!!!
This last attempt (fourth times the charm we hope) I placed a wire in the #23 pin as stated above seen in the last two pics provided in this reply. This resulted in the same green screen, but with a bunch of reddish/orange flickering lines. I will get it right one of these times. Hey I am new at this and will eventually figure it out. P.S. Thank you saltbreeze for being so patient and helping me.
