It maintains the series' trademark RPG-hybrid gameplay, but changes the battle system to accommodate the limited capacity of the GBA.
The Robos can still be customized in the same manner as the console games (Body, Gun, Bomb, Pod, Feet) but the battles take place on a 2-d plane in zero gravity.
There is still auto-aim, and the Robos have the same fire modes as the console releases.
Different arenas have obstacles, and Robos have dash moves to move around them more effectively.
Generally a Robo is based on its 3d counterpart, so a slow and powerful Robo will still be slow and powerful.
This game was originally planned to be the first Custom Robo game released in America, but Nintendo chose the Gamecube release instead.
About Game Boy Advance
Nintendo's Game Boy Advance (2001) offered near-SNES-level graphics in a handheld and became a home for excellent ports as well as original titles across nearly every genre. GBA cartridges are generally durable and plentiful, making it an approachable platform for new collectors, though a few late-release RPGs and limited exclusives have become genuine chase items.
Gamevaro tracks Custom Robo GX for Game Boy Advance with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Custom Robo GX to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This GBA release dates back to 2002.

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
