right now i have a 4tb drive with launchbox and everything installed on... i have everything setup for all the systems up to sega cd.. works great... i was thinking i'd like to expand to new systems.. i'd like to add ps1, ps2, saturn, dreamcast, gamecube, wii, wii u and maybe 3ds... would my 4tb hold all of those north american sets? or should i look into adding more hard drives... if so about how much? and is the emulation on those systems worth emulating at this point in time?
