1. Firstly, you need to add a totally new user to your PS3, no sub user please.
2. Add all the credit card information and pick Hong Kong as the country name and choose any city.
Remember, all of the information will be the same except city and country.
3. After creating the user, go all the way to the right on the main PS3 screen and choose account management
4. Choose transaction management -> manage wallet -> add funds. When you add money remember it will be in HK dollars.
5. If you go directly to the PS3 store and try to buy Tekken, it will not work because any amount over $50 dollars and Sony will check if the home address matches the home address the credit card has on file.
6. In order to get around this, add $40 HK dollars to your wallet twice, then go into the PS3 Store and purchase Tekken 5. From there, it will ask you if you want to add more funds to your account, (example $45 HK dollars). This brings you to a total of $125 HK dollars which is roughly equivalent to $15 USD, enough to purchase Tekken 5.
