That's usually what I do, but particular games are being a serious pain. Like in TWEWY, I can easily find the value for my yen, but changing it at all just corrupts the save. It shows up in two places, changing either or both has the same result. And yes, I'm not going over the original 99,999 limit for money. Any amount still corrupts. Mario + Rabbids is straight up encrypted it seems, I can't even find the coin value in there. Not forward or reversed. I did manage to find the currency in Starlink though, so that's one positive at least.
