Henrik RydgårdandClaude Opus 5 4ae682283c Path: make WithReplacedExtension(old, new) report a mismatch instead of hiding it 
It used to return the path unchanged when the path didn't end in oldExtension,
so a caller that guessed wrong silently went on using the original file - and
"the screenshot next to this savestate" quietly becomes "this savestate".
Every caller had to know to check the extension first, and most didn't.

Now it's [[nodiscard]] bool with an out-param, in the style of ComputePathTo
next door, so the mismatch has to be handled. Changing the signature rather
than the behaviour means no call site can keep the old assumption by accident.
All four callers wanted "skip it" or "fall back", which they now say out loud.

Henrik Rydgård 8c9bf04add Headless: force opaque PNG screenshots by default, add --screenshot-keep-alpha 
Games often use the framebuffer alpha channel for non-visual purposes,
so saved PNGs could look fully transparent in image viewers. Force alpha
to 255 when writing PNG screenshots unless --screenshot-keep-alpha is
passed. The MSE comparison ignores alpha either way.

Henrik Rydgård 893ac3e3db Frametests: add framedump rendering test runner and PNG screenshot support 
- Add frametests.py: walks a dump tree, renders each dump per config variant
  through PPSSPPHeadless, generates reference images when missing and compares
  MSE when present, and writes a self-contained HTML report. The JSON config
  (which lives with the test set, not in the repo) points at the data tree
  and defines variants as suffix -> CLI args, e.g. 'soft': '--graphics=software'.
- Headless: --screenshot-save saves PNG when the path ends in .png; new
  --screenshot-diff always writes a visual comparison when comparing;
  screenshot comparison failures (mismatch or unloadable reference) now fail
  the test instead of passing silently.
- Read back framebuffers top-down, flipping only for BMP output/input
  (fixes upside-down PNG references). Sync libretro copy accordingly.
- Document the system in docs/frametest.md; add AGENTS.md reference.

Henrik Rydgård b706d800cb More headless tweaks. D3D11 and Vulkan backends work, not OpenGL though, timing issue it seems 2026-07-19 01:46:41 +02:00

Henrik Rydgård a317890c08 Remove the GPUDebugInterface class 
Just a pointless extra layer in the class hiearchy, making it
unnecessarily hard to modify the interface.

Might as well hit GPUCommon directly.

Unknown W. Brackets f009d15078 headless: Allow screenshot to not be 512x272. 
Ended up with a cropped screenshot for a frame dump, which just silently
crashed.  Could reject, but easy enough to support.

Unknown W. Brackets f32e8e11ab headless: Switch screenshot error to MSE. 
This is more useful than 1/0 on whether a pixel doesn't match, when many
are close but not exact.

correct pixels.
