1  Tech and Marketplace / I need help with my game! - Technical Discussion / Re: Backwards Frogger on: July 12, 2017, 12:52:56 pm
The monitor is fine.  Since no one had this problem with a Frogger board, I looked for Galaxian boards with this problem(since they share the same video hardware) and found that someone had this problem and fixed it by replacing the octal transceiver that talks to the VRAM.

Repair log(not mine): http://wiki.arcadeotaku.com/w/Galaxian_Repair_Logs


Hopefully replacing that chip will fix the problem.

My Frogger board has a problem.
The game works fine except the sprites are backwards and some are misplaced, everything is going in the right direction, it's just backwards.
I have no idea what is causing this issue, the CPU, ROM, and 74LS201N RAM is good, no idea about the 2114s, I have no way to test them right now and I was using someone  else's test bench to test the board as I don't have my own yet. 

Any help is appreciated.
