Yes, I definitely could do that, but I avoid such measures as a general rule. I prefer to go the file-editing route. Though it's uncommon, some games actually track whether a player uses the cheat methods a game offers, and it can/will affect various aspects down the line. Side-stepping such functions by directly altering the save data ensures all potential paths remain available, because cheater flags aren't tripped in the process.
If I were solely intent on seeing the lewd content, I could beg for full saves like so many others, but I prefer to go through a game on my own while ensuring that I can fully explore what a game has to offer without spending time grinding away.
I also generally learn various things just by looking at the data. Having some idea of what's in the various game files informs me on what components of the code I might decide to modify, and how to do it without causing errors, in the event I want to change the behavior to some degree.
I do understand, however, that some people don't want to dig through data for any particular purpose, and most likely don't enjoy dinking around with program code. I do enjoy it, however, so I'll keep doing it.
