yeah, the main issue with emulating this way the link works on these games is that your PC monitor will never be quite in sync with the game (unless you're dynamically adjusting the PC monitor sync, which I guess requires gsync / freesync) It will likely end up picking a sync point that while is the same for all the emulated machines (in vblank) is in the middle of your actual screen for your PC monitor (thus causing some tearing) at least if running across a network. If you're running two machines on the same PC then in theory if you start both displays at the same time, and both are already perfectly synced, the game should know that.

as far as the emulation is concerned tho, you can increase / decrease the target frequency as required, the only thing that suffers slightly is the presentation because your actual monitor frequency isn't changing.

we'll likely run into the same 'system vblank time is not in sync with PC monitor vblank time' with other emulated systems that dynamically generate their sync signals and can even run unsynced at times (eg. zx81 where there are no sync signals during loading, but will start generating sync signals again once finished) but again, it's a presentation issue that freesync / gsync likely solves.
