ON PC is always going to be an imperfect experience unless the game is made for PCs (and even then it's going to be subtly off unless you use the same PC and monitor the developers did, and calibrate the monitor as appropriate).
So, yes, if you're as wound up about perfection as the poster here is, the PCB and a supergun are the only way to go. MAME actually plays PS1-hardware games like G-Darius more fluidly than they're supposed to be due to the current lack of GPU timing emulation, for instance.
