cannot even do snes worth a beans
Not true. For SNES, take a look at DreamSNES. It has pretty good compatibility and 80-95% speed, depending on the settings. Also, SNES4All, since it's under active development, should be surpassing DreamSNES soon. I would keep an eye on that.
it is a good console still but just does not have much horse power under the hood for emu's.
Once again, that's not true. Sure, some games won't run on the emulators, or some run too slowly. But, for the most part, DC emulators are good (and there are a lot of them):
NES: NesterDC
SNES: DreamSNES
SMS: SMSPlusDC
Genesis:
Segagen GenesisPlusDC GPWT
2600: StellaDC
GB/GBC: DCGNUBoy
GBA: gpspDC
TurboGrafx-16: PCECast
...and that's off the top of my head.
