For the vast majority of people, CRT shaders come close enough to approximate the look of a CRT, but IMO nothing beats putting the cartridge into the system like 3 times until its exactly flat and works, and the plastic of the controller.

It is of note that emulation is almost a moral obligation at this point. There is no reason that random Billy Joe needs to be charging people $900 for Panzer Dragoon Saga on SEGA Saturn. These games should be $5-$10, to allow all people to be able to experience what came before. And emulation is the solution. Plus, nearly none of the games people emulate are legally purchasable from the publisher or developer anymore.
