However, he wasn't meant to throw quicksave into the mix but it worked out nicely because we can now have multiple quicksaves, or just one, and turn off autosave too, or play on hardcore mode for restrictive saving, all up to the user. In my defense I didn't code the system either, I did have a modding partner at one point nearly four years ago now, great guy and props to him, though I did design it. Honestly, I would make them entirely independent of each other but there's simply no need (except perhaps to avoid confusion, I guess), and it expands upon how quicksaves usually work by letting you have multiple user defined slots. This will ensure the autosave upon level transition doesn't overwrite your most recent quicksave too, if you don't want that to happen for whatever reason (or you can just turn autosaves off). But you may want to set it to something like 3 - it will cycle through three quicksave slots, and quickload will load the most recent one, or you can load an older one from the load game screen. Setting it to one slot will act like normal quicksaves.

any number from 1-20, or increase the cap further from gmdxuser.ini.

Go into GMDX options and set a cap on autosaves/quicksaves (default = 10, perhaps a bit too many).
