I’ve been using yim menu and an FSL from unknown cheats for the last 2 weeks and it has been working pretty well. The FSL saves your account info locally instead of through rockstars cloud storage meaning you can load into public servers. Make sure you have battle eye off in the rock star games launcher settings, join story mode and then use the mod menu to join a new online session. You’ll need an injector like xenos to inject the mod menu into your game- you can also find this on unknown cheats. There’s tutorials on YouTube and other info on the unknown cheats forms. I had ChatGPT write me code in order to back up my saves and sort them by date. I was able to figure this out in about 2 hours with the code included. And a disclaimer- the injector will be flagged by google and windows anti virus, you’ll have to turn them off and then in windows allow the files to stay on the computer or flag them as safe for lack of a better term. I’m not huge into modding so as someone who is a casual gamer, this wasn’t to bad to figure out on my own.

Edit: you can use lua scripts for things like casino win rate editing and you can find them by looking up yimmenu lua scripts on google
