hmm just a quick check, does the eShop still
- require you to "give up" the existing funds in your eShop wallet before you change region?
- require a US Credit Card for the US eShop?
1. Yes your account have to have no value in order to change region so for us that change often, use the pay the exact amount option. Good thing is any purchase you buy in a single account the gold coin accumulate so u can focus a major rebate on 1 game .
2. No issue using credit card/debit from Singapore. Just note the bank now may block your transaction due to their tight security so give your bank a call to lift the block.
