SNES games that may not be compatible

[jld4snes]

Hello, 
   I have been using my Retrode 2 for well over a year now and I had not had any problems dumping my collection.  I picked up ten games or so recently and of those I have had no luck with the following games:

Gradius 3
Super Tennis
Chess Master

*I have cleaned the pins with isopropyl alcohol and a q-tip
**I have modified the Config file to force "snes" and tried numerous sizes to force as well.

Has anyone else had problems with these games? 

Thank you.

Are you using the most recent firmware, v0.25a? Do you have the voltage switch set correctly?

Yes and yes.

I think this is an issue with my Retrode which is really disappointing, as I have gone back and tried to use it on games that I have already dumped and it is no longer reading those either...

Can confirm Gradius III US is compatible with my Retrode.
