How to remove an optional LibRetro_core from retroarch

[eidern]

Hello, 

I was setting up the necPC engine module with retroarch, and I accidentally messed up by adding in the hyperlaunch emulator config an default .dll in the "LibRetro_core" field.

Since that the emulator cannot launch, so I try to let the field blank (as it was at first), but in fact you don't have the option to let it blank now..

How can I do?
