Well I actually bought them to use with the 2600-dapter D9 which they're supposed to be compatible with. The problem is that the "nubs" are preventing me from connecting them to the adapter.
I bought 2 of these to use with a 2600-dapter D9. The problem is that these controllers have nubs on the D9 connectors that prevents them from connecting to the adapter? Does anyone know the reason for this?
