I was totally against using RA for the longest time but after learning how to use it and seeing the improvements that it made over other stand alone emulators. Every thing handheld is much better than the stand alone. Its the best TurboGrafx/PC Engine emulator I've ever experienced. I've personally never tried to use FBA stand alone but I know that Kawaks also crashes if you try to use true full screen. You can set it to use Windowed full screen but in my opinion it looks like shit and it is just a PITA altogether. RA means not having to set up your controllers (In most cases). I'm not trying to force you to use it like LordMonkus said but I strongly suggest you watch Jason's video it will give you a base to build upon when setting it up and then start watching Brad's video tutorials on how to set up specific systems his videos are great at teaching you what you need to know. Like I said I was totally against using RA. I wanted no parts of that it was a pain and unintuitive, but after finally starting to use it I'm totally converted and use it for almost everything that I can except MAME and ePSXe.
