Custom Robo GX is one of those GBA hidden gems—if you're into fast-paced robot battles with a surprising amount of customization, anyway. You start off picking a basic robo frame, then immediately dive into tweaking its weapons, legs, and special moves. At first, I just slapped on whatever looked cool, but after getting wrecked a few times, I realized there’s actual strategy here—some combos straight-up don’t work together.

The battles are chaotic in the best way. Tiny arena, four robots dashing around blasting each other with lasers and bombs. It’s got that classic Custom Robo feel, just scaled down for the GBA. The story’s barebones (typical "rise through the ranks" stuff), but honestly, you’re here for the robot tinkering and quick matches. Perfect for short bursts or grinding upgrades between classes.

If you missed this one back in the day, it’s worth digging up—especially if you’ve got a soft spot for mech games that don’t take themselves too seriously.
