Online save editor is your friend here, you can add money change stats and add items. Or search cheat mod editor on here for programs.I know I am late to reply here but, is it too late in development to add a money cheat as long as the game is still developing? Cuz most semi-major updates in the story means starting from the beginning, and the shop grind is just redundant (Maybe an option to just start with couple thousand dollars for repeat players?)
No more question about which to use, google is your friend use it!
