Emulators are meh. I find that people tend to cheat using save states. (Where you can save at ANY time and reload the game from where you saved)
I only use emulators for non-american games.
I use save states after I've beaten a difficult part such as when the storks start spamming those hunchbacks.
Well I use a plethora of different emulators for each system because ROM hacks and the like will not work on many emulators.
These are what I found to be most effective:
NES: VirtualNES or FCEmu
SNES: ZSNES or Snes9x (Rom Hacks)
N64: Project 64 or Nemu 64
GB/GBC/GBA: VisualBoy Advance or NO$GBA (Also use for DS since i have a touch screen)
Jaguar: Tempest
Sega Products (Except Dreamcast): Fusion
yeah, ok.
i only have 3 emulators that work (well, 4 if you count ti-pc)
gba: VisualBoyAdvance (super robot wars taison 1&2 ftw!!)
n64: Project 64(007 goldeneye, perfect dar, super smash brothers)
nes: nester (mega man series)
i also have psXone i think it's called for psX, but i can't get it to work!!
I've downloaded project 64 to play goldeneye but the controls are crap with arrow to aim and z and x to do stuff. Does anyone know how to get my mouse to aim for the guns and stuff?
