FEAR was created to be the simplest implementation of everything I needed in a FE. Designed to be run on an Arcade Machine or a PC. (in a "hide-os" fashion)
I tried alot of others, and I liked alot of them, but they all had some issue that didnt work out for me.
FEAR is small (24k executable) and easy to setup/use. It's not as feature rich as some other fe's, but that is the whole point really.
Hopefully someone else will find it useful.
