Struggling with hardware of build

[admin89]

Or just by Alienware Alpha (i3 4170T @ 3.2GHz + GTX 860M for less than $500, you can get a used one on ebay for like $200) , strip off the case and put it in a NES , Gamecube or any console you want
and then you will have a solid device for emulation , all game can be played at 1080p ,isn't that better ?

Quote: is it possible to play the Gamecube games with Nintendo 64 controllers, or do I need dedicated controllers for both uses?

You can use any controller you want as long as it's recognized by the OS
As for me , I use Wii Classic Controller with USB converter adapter and PS3 controller with motioninjoy (a Xbox360 controller's emulator) .
