Save state for old games

[Mathantastic]

so, I've been playing wonderland secret worlds, an old puzzle PC game from the early 2000s, and its very good, the only part that doesn't really hold up nowadays, is that there is no way to undo or retry any small mistake you did in a game, as it is common on most modern puzzle games. Instead, you need to redo the whole level, wich can sometimes be like 5-10 minutes long. Is there any way to save state a point, kinda like how you do on an emulator, so that I can reload it from that point and not have to redo the whole level? This is a very very very light game, so performance is not really an issue here. I just tested it, and it tends to consume only around 70mb of ram, and 0% of my CPU lol

On emulators this is pretty easy to do since you're essentially saving the state of the hardware/system rather than the game. This is also how things like VMs can be resumed since they save the entire system rather than portions of it. It's extremely difficult to externally save the state of a single process within the system when processes are heavily managed and intertwined like they're on modern operating systems. Without getting into some pretty heavy reverse engineering, you're going to be screwed, and since you're asking, you obviously don't have the skillset or knowledge required (no offense intended).
