Retro Game Challenge, the English-language version of Game Center CX: Arino no Chousenjou. When XSEED showed the newly-announced US version of the game at E3, they simply used retail Japanese cartridges in the demo units. We asked the XSEED rep at the time how they planned to approach localization, but they weren't talking yet.
The good news is that not much has changed, other than the words being in English. The young Shinya Arino character is still Arino, and the Famicom on the floor still looks like a Famicom. We can see from a very quick flash of the menu that the magazines are still there; we were a bit worried that they would be left out.
