Since this games store their savefiles along with their binaries, progression is impossible on Nix. Savefiles cannot be created nor deleted, money cannot be earned, settings cannot be changed and trophies are not saved.
To make the games playable, I have added a default savefile with all the money you will ever need, alongside sane settings. This solves most problems, except the trophy room issue, which I do not expect to fix.
If you are the rights holder for the franchise and want this flake taken down, please contact me and I will remove it from GitHub.
