Symmetry One // Advance

One-thumb GBA skin, either hand. Portrait puts the whole game on top and mirrors every control to both sides: A/B pairs, both shoulders in each bottom corner, START/SELECT in each top corner, SAVE and fast-forward under the screen. Landscape is a two-hand layout with outline controls floating over a full-height game. Built from original art.

Themes, one file each:

• Dex: Symmetry-One-Advance-Dex-1.0.0.deltaskin — The Dex Theme: red body, dark grey deck, blue rings, white labels.
• Hero: Symmetry-One-Advance-Hero-1.0.0.deltaskin — The Hero Theme: two forest greens, wood controls with gold rings, a Hylian blue hairline around the screen.
