I understood. Thank you, sir. I tried changing the staff upgrade to negative and to 1 on GameGuardian but it also gives error so I thought it might be possible for expenses because they're more glitchy. But here is something; I changed the level of red wine to 1 million and it gives 5m cash everytime I serve to customers.@FALC0N believe me i tried negative. it gives a error, the same for 0 amount. Thats the reason for 1 token cost. I can only change things on the main screen. Other things are serverside.
For modding you need c++ knowledge. Assembly is dying out. nearly every game has .so files.
