Photos taken while playing on Super Game Boy. ROM version: 1.1 (Front marking A) ● Terminals have been maintained, so recognition is good. ● Due to being a used item, there are scratches and signs of use. Disinfected and cleaned. ● The voltage of new batteries is checked before installation, and those with low voltage are excluded. ● Immediate purchase without comment is okay, so thank you. :-) ※ If you wish to initialize the game, please let me know via the transaction screen, etc. #UkiukiGB #UkiukiBatteryHolderSoftware #UkiukiCustomMade #UkiukiRPG #UkiukiPokemonGames #UkiukiGameFreak #UkiukiNintendo #UkiukiDifferentVersion
