How do I make all those *bank files and *.ini files independent for every game ?

I would not like to overwrite original files or make backups of them with every game I make.
Or is it even possible ?

My Game guru Max is not installed in Default at c: drive.

Game guru Classic is at Steam Folder (but not in c: drive).

How to make those startup screens and other things individual for every game ?

Hi Jokke. I'm not sure that there's really a good way to separate game projects for GG.
The engine is created to be a "Game maker for everyone"-- so there's all these stock
settings already setup in the folders, etc with little flexibility on multiple projects.
Unfortunately-- in my opinion.

And there's no indication that MAX will include a game project system either.
But it would definitely be handy!!

For those questions you have, I suspect that you can try the Youtube Game Guru
channel to find some of the answers, you would have to pick through all the
posts and see if you can find them. It's kinda simple, and kinda complicated, and
some of the videos are horribly outdated and very long and rambling.
It needs a whole new update with succinct videos posted, (as new data comes in...)
