This is a very easy way to get a load of coins very quickly!
Native, Pineapple King, Master Lox, or Henchman (unhacked) or access to 'Coin Caper' or 'Eruption!' Unhacked. (Using Eruption gives more coins.)
1.) Navigate to your 'games' folder in the Funkey files. It should be at: 'C:\Program Files\U.B. Funkeys\RadicaGame\games\'
2.) Find your game ('Eruption' or 'H_games') and add a 1 to the beginning of its name. (1Eruption or 1H_games)
3.) Locate the game 'museummaskmayhem', and rename it to your game's original name. (Eruption or H_games)
4.) Play your game. When you do so, it should be Museum Mask Mayhem and not really your game. Get a decent score on it, and you will be showered with coins.
5.) To return everything to normal, press Ctrl-Z twice in the folder.
