Atari 5200 games won’t load after mod

[shear_xear]

Hi everyone.  I just completed modding a four controller port Atari 5200 with the power mod as well as a UAV mod and now some third party games won’t load.  Is there a known issue with the power mod making some games no longer load on the four port 5200’s?  I can’t imagine this being the fault of the 5200, but I suppose anything is possible.  Any help would be great.  Thanks!

Try cleaning the cart port on the 5200. Some of the 5200 third party games have thinner cart boards and are more prone to failure. It doesn't hurt to clean the cart as well.
