K Fusion - Recording in HD

Hey Y'All:

I'm looking for help. I am trying to record videos on K Fusion 3.64. I am trying to figure out how to get better resolution. The avi file it creates is only 640x480. Is there a Codec or Plugin that can change the output to HD or at least 800x600? I am not looking for suites. I use OBS, but I have lag issues with K Fusion. I'm looking for a native fix to K Fusion if possible!

Thanks for your time,

MicahLuv

use OBS for recording and Kega Fusion is defunct, use RetroArch with the Genesis Plus GX core, it destroys Fusion.
