Requirements for light emulation?

I want to play old games on an android game/tablet emus of NES, SNES, GB+GBC, GBA, Sega Genesis/Game Gear, but also CPS 1-2-3 and neo-geo.

It’s possible to runs those emus on an android handheld, It has 1.2GHz CPU -single core- with 512M of RAM, is this enough for mentioned emus?

It should be enough for NES, GB/C, Genesis/GG and CPS1/2 and NeoGeo. SNES will be borderline at best, GBA and CPS3 will be too slow.

I have an Xperia Play at 1Ghz and 512mb.

Play perfectly:

Final Burn Alpha ==> (3rd Street Fighter III, Garou … Perfect) Mame 0.78 ==> (all games Mortal Kombat least 2/3 and Killer Instinct) Megadrive, MegaCD, 32X, Gamegear, MasterSystem, SG1000 ==> Perfect. Pc Engine / CD, Supergraftx ==> Perfect Virtual Boy ==> (overclocked to 1.4Ghz pefect) PCSX Rearmed ==> Perfect Nintendo NES / Gameboy / Color ==> Perfect Wonderswan ==> OC 1.2ghz perfect. Atari 2600/Lynx ==> Perfect. Cave Story, Doom, Quake ==> Perfect! (if you raise the resolution better OC)

Super Famicom ==> SLOW! (But perfect with snes9x.EMU) Game Boy Advanced ==> SLOW! (But With perfect GameBoid) Nintendo 64 ==> SLOW (But playable with N64oid) Nintendo DS ==> SO SLOW! (But perfect with DRASTIC & 1.6Ghz OC)

Hope you helps.

Thank you very much, that’s what I’m looking for!!

One more question: what about SFX (Star Fox, Yoshi’s Island), SA-1 (Kirby Dream Land 3), CX4 (Megaman X2) chips emulation on snes9x.EMU -is that Snes9x EX±? or Donkey Kong Country 2 in Gameboid? -in vbam second scene in game sometimes gets slow on intel atom pc while playing-
