Moates is still there. The Ostrich is the emulator that I used. It's $175.00. The software TunerproRT. It's $39.00 for the pro version. I don't remember what the $$ gets you, I think it was just a splash screen, but it's good software. Well worth the $39.00.

You can do a search for e53 bin files and Tunerpro definition files for the e53 and you should be able to find a rabbit hole pretty easily that will keep you up past your bedtime.
