Adds 8x and 16x internal resolution, alongside 2x, 3x and 4x. Enable Higher Internal Resolution in Mods and select a scale. 4x remains the initial selection. 8x and especially 16x can run substantially slower; full speed is not guaranteed. Original sprites and HUD artwork retain their authored resolution.
Single-player widescreen is now selectable in Display:
- 16:9 gives a fixed wide race view.
- Adaptive fits the window or fullscreen display.
- Native (3:2) keeps the original framing, including side bars on a wide display.
- Default (Mods) preserves existing widescreen mod selections. Explicit Display choices take precedence.
The Netplay page's view setting applies separately to online play. Live Native/fixed/adaptive switches now reset SDL's viewport correctly. Large textures fall back to a smaller upload if required by the GPU.
Validation includes HLE/LLE renderer tests, actual 8x/16x race captures, course-intro regression checks, canonical state/rollback differentials and bounded Windows/Linux netplay checks with different local rendering scales. This is not a full campaign or sustained Internet playtest.
Supply your own supported USA ROM and retail GBA BIOS; neither is included. See validation details.
