Making a Repro Using Sx-ROM

Post by Izen6 » Sun Mar 08, 2020 7:34 am

Hi everyone,

Sorry if this is not allowed or not in the right place. Will delete or move the post if needed.

I'm trying to make a repro of Chip's Challenge for NES for myself and I'm using an SG-ROM donor board as there is only a PRG that is needed. I tried wiring everything up using the following guide:

Using a 27C040
Bend up pins 1, 2, 24, 30, and 31
Connect pin 1 to hole 30
Connect pin 2 to hole 24
Connect pin 24 to pin 16
Connect pin 30 to hole 1
Connect pin 31 to hole 2

The game does start and goes to the title screen, but when I start to play it brings me to a level and the character is not there and nothing happens. I can pause the game and skip levels, but it's like Chip is missing. Any thoughts? Thanks!
