Thank you for viewing. This is the North American (US) version, cartridge only, of the GBA game "Mega Man Battle Network 4: Blue Moon (Rockman EXE 4: Blue Moon)". ✅ Authentic, Serial Number: AGB-B4BE-USA ✅ Operation confirmed ✅ Plays well ⚠️ As this is an old game, reading may occasionally become unstable. This can be improved by re-inserting the cartridge or cleaning the contacts. Please check the condition in the photos. I am selling this to organize my collection. ⚠️ No returns, as a measure to prevent swapping. #RockmanEXE4 #BlueMoon #RockmanEXE #MegaManBattleNetwork4 #GBA #GameBoyAdvance #NorthAmericanVersion #Authentic #Collection
