From Capcom's Website:
I need a replacement for a damaged game disc.
In some cases a replacement is not the best solution. Our support representatives will help you determine if a replacement is necessary or available. You will need to first acquire an RMA (Return Materials Authorization) to process your return or replacement. Without an RMA from a support representative, your replacement request will not be processed.
# If we determine a return or replacement is necessary:
* Within the 90-day warranty period:
Please return the product with its original box and manual along with a copy of the original sales receipt, showing the date of purchase, a brief description of the difficulty you are experiencing including your name, address (no PO boxes) and phone number to the address below. If the product was damaged through misuse or accident (cracks, scratches), or if you do not have a dated sales receipt, then this 90-day warranty is rendered void and you will need to follow the instructions for returns after the 90-day warranty period.
* After the 90-day warranty period:
Please return the product with its original box and manual along with a check or money order for $20 made payable to Capcom, a brief description of the difficulty you are experiencing including your name, address (No PO Boxes) and phone number to the address below.
