You can't. This has to do with the BIOS in your Neo. You would have to swap the BIOS chip itself for a US BIOS chip, or piggyback one onto the existing BIOS and add a switch to select between the two for an English memory card menu (or so I have been told). Also, the DEBUG BIOS will not help either: I had a Japanese Neo Geo modded with the DEBUG BIOS, and had the default language set to boot up with the USA territory. So, even though the language on my Japanese console is now English by default, the memory card menu still displays in Japanese (I was told all debug BIOS chips display a Japanese menu for the memory card). If anyone has another workaround for zapr's issue or mine, please post a reply.
