Adds the DuckStation-style widescreen hack as a config option, implemented in the runtime (no regen needed): - gte.cpp: gte_set_display_aspect(num, den). RTPS/RTPT scale the IR1*h/sz screen-X term by (4*den)/(3*num) around the game's own OFX projection centre (identity at 4:3). Games cull against the SXY values they read back from us, so post-projection screen- bounds culls stay aligned with the visible frame. - present: GL letterbox_rect generalised to the configured aspect (gl_renderer_set_display_aspect); SDL_Renderer path gets an aspect-derived logical size + dst rect. Window opens at the configured aspect (clamp_window_4x3 -> clamp_window_aspect). - config: [video] aspect_ratio = W:H (4:3 default, 16:9, up to 32:9) in game.toml, settings.toml (load+save), launcher seed. World geometry keeps correct proportions on the stretched present; screen-space 2D (HUD, FMV, sprite quad widths) stretches — the known limitation of the squash tier. EXPERIMENTAL.

|
||
* renderer goes through Windows GDI; the GDI path hangs the SDL
|
||
* main thread under heavy emulation load.
|
||
* 3. Bisection: NO_AUDIO+NO_RENDER ran indefinitely (~7+ min, 40k+
|
||
* frames) but the game never progressed past BIOS boot because
|
||
* it depends on the renderer being present. NO_AUDIO alone with
|
||
* software renderer froze at frame 3084 — same as full debug
|
||
* build. So audio is innocent; software renderer (GDI path) is
|
||
* the culprit.
|
||
* 4. SDL_HINT_RENDER_DRIVER=opengl + SDL_RENDERER_ACCELERATED.
|
||
* Ran indefinitely past every prior freeze point. OpenGL driver
|
||
* uses a different presentation path that doesn't hit the GDI
|
||
* hang. This is now the default.
|
||
*
|
||
* Note: the freeze became prevalent only after the FMV-speed fix
|
||
* (commit b486c13) raised cycle throughput. Before that, the slower
|
||
* MDEC/DMA workload was below whatever GDI threshold trips the bug. */
