So I've recently discovered this game, I've been playing stracciatella for a while and I found the most enjoyable way to play is the Dead is Dead mode (where you can't reload your save, it saves automatically when you quit the game or load another save) because it eliminates the temptation to reload when I lose a merc or a battle goes bad (I'm aware ironman exists but it isn't the same because I can still restart battles whenever i feel like it and try different strategies risk free). I've got 1.13 up and running fine and have been tweaking it for my next playthrough, but I can't seem to find how to play it in Dead is Dead mode like on stracciatella.

I've found a "JA2 roguelike" mod online that I think the stracciatella mode is based on, but the instructions are only clear on how to install it on vanilla 1.12, and because it creates its own ja2_options.ini file I cant figure out how to incorporate it into 1.13 as obviously that also has its own ja2_options.ini, I've scoured all the documents for 1.13 looking for "roguelike" and "dead is dead" but I can't find anything about it, so I'm relatively sure the mode is not built into 1.13 although hopefully I'm wrong about this and it's an easy fix somehow.

Does anyone have any idea how to get this mode in 1.13? I've attached the roguelike mod i found online if there's no easy option to activate in 1.13 somewhere just in case someone can take a look at it and tell me if it's possible at all. Thanks!
