v0.5.0
The biggest update yet: true widescreen and a full Gen 4-style dual-screen battle experience.
True widescreen
- The software PPU now renders wider than 240px natively, no more stretching. The overworld draws a 512px-wide background with vanilla game-space coordinates, so you see more of Hoenn instead of a zoomed crop.
- Widescreen-aware windows and sprite decode. Display-mode changes no longer undo the widened frame.
Gen 4-style dual-screen battles
- Battles take over the bottom screen with DS-style menu geometry: commands, moves, bag, and party all playable from the bottom screen.
- Full input parity: touch or physical buttons, whichever you use. The cursor follows your input method and mirrors the engine cursor.
- Forced send-outs, bag, and party open on the bottom screen mid-battle.
- Optional battle hints (HINTS setting): pixel-caret type-effectiveness markers with multiplier tiers, and the foe's weaknesses on its card.
New bottom-screen UI
- Emerald-authentic redesign of the panel UI.
- Party tab: 2x3 grid of rich party cards using the game's own palettes.
- Bag tab: laid out the way the DS bag does it, with item descriptions.
Stability
- Bounds guards on raw window ids in tilemap/VRAM paths and on Battle Dome facility ids. Fixes a class of crashes unique to running the GBA code natively.
