The file format is almost the same; just a few changes and additions for Riptide.
Game-saves for the Steam copy of the game have the file extension "sar" rather than "sav", but nothing's different about the compression. For some reason, the game's app ID is the same (in my case) as the first game game (why, when it's a different game?). Because of this, the saves are stored in the same folder, and I guess that's one reason why they chose "sar" to not conflict with the old naming. May I guess that the "r" simply stands for "Riptide"?
DISE and RiptideDISE v0.0.55.34 doesn't support Riptide at all since the file format is a bit different. I'll release v0.1 soon, but I've only just started working on Riptide. It may be better to keep a stable version of DISE, and an unstable one for Riptide, so I'll need to find a way to do this properly.
I'll give out a bit more info in the coming days. :)
Trainer and Riptide (PC only)Someone on the chat mentioned a trainer for Riptide, and allegedly, it costs money as well. As long as one can try it first, I don't have much to say; however, mine will always be free, and I think this is enough to motivate me to support Riptide. :)
Maybe not, but at least it's proof that I'm doing something. :)
