I love old consoles... but old media (carts, cds/dvds) not so much. Flashcarts have been a revelation for me. I'm happy to help out the collectors out there by lowering the demand for original cartridges for my NES or gameboys.
And honestly its a much purer and more fun experience than an everything emulator where you spend most of your time setting it up and then deciding which game of all the games ever created you feel like playing right now. But I do also enjoy setting up emulator devices be they handheld or set top, and playing on them. I'm not a snob, it's all good stuff and its a great time no matter what your choice, tbh.
