Emulation and digital media in general definitely has its place, but as a collector I need the physical cart. I want to get into eprom programming to do my own eventually, but I just don't have the time.
Just bought a raspberry pi, so will probably use that as a dedicated emulation machine for now. Although, I also just bought a new pc, so I want to build the old pc into an arcade machine for emulation too. So many projects, so little time. lol.
So, I've not really answered your dilemma, other than, buy everything, and emulate it too. 😉
