Infinite Money Glitch
At one point in the game, there is a sub story and you will get in a dance battle with Miracle Johnson. After you get slaughtered, he asks you to pick a prize. PICK BLACK. This will get you the encounter finder. When you equip it, it will show you the location of Mr. Shakedown on the map. This isn’t necessary for the money trick, but it will save you a ton of time and grief having to manually find Mr. Shakedown every time you are looking for him! Next you want to make sure you have spent the CP at the shrine so you get more money from Mr. Shakedown after you win. Then you want to start the process of losing and winning over and over, making more money each time you win. In a short time, you can easily max out the money counter to buy stats, real estate, and even send money to Majima!
