I have a Hong Kong version of PS3. I just bought a HK import version of RDR. It's an actual US version. The version is also only one version which available on HK.
There is a serious bug in the button config. O and X button setting confuses gamers. When start the page. press start, Menu says press X to begin single play. But In Hong Kong version of PS3. we can only press O to begin single play. that means O and X is configed different from US version of PS3. The big problem here is some times O X button config in menu is correct as it says. some times it's wrong. Another example is in Poker mini game. Same button is configed for both of Call and Quit. That means the mini game is unplayable!!!
