Finding runes and unlocking the Black Market
Select a card you have obtained, and choose the "View Card" option. Rotate the card in every possible direction to potentially find a rune. A rune looks like an alien symbol and appears in the left border area of the card, below the "Ovr" rating. It is very rare to find a rune. Once you find five different runes from viewing and rotating cards, you will get a special rune code that gives you temporary access to the Black Market. The Black Market allows you to purchase special items, such as a Zebra Ball, Exclusive Rookie of the Year Winners Box (contains 10 Rookie of the Year packs; each 5 item pack includes a single player with the highest chance of pulling a Rookie of the Year card), Diamond Air Jordan III (can be applied to any player and has unlimited uses), and Diamond Contract Card (adds infinite contracts to any player when applied).
Start a game in myCareer, set the difficulty to "Hall Of Fame" with 12 minute quarters, and simulate it to the end to get approximately 400 to 800 VC each time, depending on the stats and how well your player negotiated. The process should to take under two minutes. Repeat this as many times as desired. You can also start a second career if you do not want to have any simulated games under your main career. Note: It will say no VC is awarded for simulating a game, but it will be awarded as long as the game has been simulated once the ball has been tipped-in. This glitch was performed on an unpatched version of the game and has now been patched. Delete or do not download patches for this game and disable your internet connection to use the glitch.
Start a game in myCareer and set the difficulty to "Hall Of Fame" with 12 minute quarters. When the game begins, foul out as quickly as possible to get approximately 350 VC and at least the base salary. You can foul out in under two minutes. Repeat this process as many times as desired.
Note: This trick requires you to take losses in MyPark mode. Thus, you may want to create a separate account to use this trick on. Enter MyPark mode, and find a game. It may be easier to find a game with a couple of other players. Once the game begins and the ball is passed in, simply quit the game. You will take a loss, but you will earn approximately 500 VC. Repeat this process as many times as desired. Note: Sometimes when you try to join a game again, it will put you back in the same game you already quit. If this happens, simply quit the game again and try joining a different game.
