There is a known bug in FCEUX 2.1.5 (and older) that causes it to crash on startup when running on newer SDL versions. I am not sure the exact SDL version that introduces this. There are two possible ways to resolve this: 1. bump package ala #466382 - using the ebuild attached here in my personal overlay fixed it. 2. apply diff from http://ehc.ac/p/fceultra/code/2268/ if there is a reason to not bump package - adding this patch to 2.1.5 also fixes this issue. Reproducible: Always Steps to Reproduce: 1. emerge fceux 2. Attempt to start it. Actual Results: Starting FCEUX 2.1.5...

should be fixed in fceux-2.2.2
