Guilty Gear X: Advance Edition (ギルティギア ゼクス アドバンスエディション, Giruti Gia Zekusu Adobansu Edishon) is a port of Guilty Gear X to the Gameboy Advance, developed by Arc System Works and published by Sammy Corporation. It is the only game in the Guilty Gear series to be released on the Gameboy Advance.
Being a port of Guilty Gear X, the gameplay is very similar to that of the original game, albeit simplified due to the Gameboy Advance's hardware limitations. Advance Edition adds a variety of extras, some of which were previously exclusive to Guilty Gear X Plus. Along with the Arcade, Survival, and Training modes from the original game, Advance Edition adds Tag and 3-on-3 modes. In Tag mode, the player selects two characters, which can be switched in-game; the character not in play slowly regains health. In 3-on-3 mode, the player selects three characters, who fight in the order that they are selected; characters cannot be swapped unless the previous character is defeated, similar to the King of Fighters series.
"Extra" versions of characters can be unlocked, similar to EX versions in later games. Advance Edition includes all playable characters from the arcade version except Robo-Ky (who's moveset has been implemented into Ky Kiske's extra version). Character colour palettes can be edited, but they do not inherit black select and gold select powers as they do in Guilty Gear X Plus. Upon completing Arcade mode, an ending is displayed, unlike the North American and European releases of the Dreamcast and PlayStation 2 versions.

Being simply a port of Guilty Gear X, the plot in Advance Edition is exactly the same.
Reception for Advance Edition has been mixed. IGN gave the game a positive review, awarding it 7 out of 10. It received lower scores from GameVortex and DailyGame, earning 6.5 and 4 out of 10, respectively. The added modes and options, such as colour editing, were praised. Common complaints were the low-resolution textures and frame cuts, and the low sound quality, specifically the music, as a result of the game being ported to a handheld system, which many reviewers felt ruined the game's distinctive style.
