* Run libSceRtc LLE
The more we've used our HLE, the more issues we've had with it.
While we debug these bugs, re-enabling LLE will address any regressions the swap caused.
* libSceJpegDec LLE
Needed for Trackmania until we implement HLE for this library
* libScePngEnc LLE
Needed for Minecraft until we implement HLE for this library
* Update documentation appropriately
* libSceJpegEnc LLE
By @georgemoralis's request
On real hardware, each pool commit can have multiple physical memory allocations, always allocating the lowest free physical addresses first.
Currently, since we currently only support one physical mapping per VMA, I create a separate VMA representing each physical allocation we perform.
* lseek for directories behaves correctly when final index is smaller than 0 (EINVAL)
Backported and improved dirents from QFS
Normal directory dirents update on change
* PFS moves pointer to end when last dirent is returned
* Correct entry type in PFS directory
- Updated RenderCodepointToSurface and RenderCodepointToSurfaceWithScale functions to set result->transImage to nullptr instead of result->stage.
- Modified font definitions to use updated font file names for various language sets.
- Introduced ResolveSystemFontPathCandidate function to streamline font path resolution, allowing for better handling of font directories.
- Enhanced LoadFontFile function to check for font files in "font" and "font2" directories based on the parent directory name.
- Improved error logging for font path overrides in ResolveSystemFontPath function.
This commit introduces a new header file `fontft_internal.h` containing
various structures and functions for managing font handles, layout metrics,
and rendering operations. Key additions include:
- Definitions for `FontHandleOpenInfo`, `FontHandleStyleStateTail`,
and `FontHandleOpaqueNative` to encapsulate font state and properties.
- Layout-related structures such as `HorizontalLayoutBlocks`,
`VerticalLayoutBlocks`, and their respective I/O structures for
managing layout metrics and effects.
- Functions for computing horizontal and vertical layout blocks,
along with utility functions for handling layout words in byte format.
- Stubs for library functions related to font management and rendering.
These changes aim to enhance the font rendering capabilities of the
shadPS4 Emulator Project, providing a robust foundation for future
font-related features.

* Remove SceKernelInternalMemory mapping
Contrary to my initial beliefs, this is very much a hack.
* Unreachable for unpatched code
This will always infinitely loop, making logs extremely large.
* Update linker.cpp
* Patch stack checks done using fs:[0x28]
Additionally adds support for multiple patches per instruction, since this makes two separate patches we need to conditionally perform for mov instructions.
* Missing include
* Disable patches for Apple
Mac can use their native FS segment directly, so these patches aren't needed
* Oops
Removed env‑driven debug scaling (ScaleMode, GetScaleMode, GetScaleBias, SHADPS4_FONT_SCALE_*).
Added FontState::is_otf_cff and storing of external vmetrics (ext_ascent, ext_descent, ext_lineGap).
Introduced ComputeScaleExtPoint, ComputeScaleExtPixel, IsEmProfileExternalFont and ComputeScaleExtForState to choose ascender‑ vs EM‑based scaling per font (system fonts + CFF → ascender; selected TTF profiles → EM).
Updated callers (sceFontGetCharGlyphMetrics, glyph cache, layout, renderer, clones, scale setters) to use ComputeScaleExtForState instead of ComputeScale / ComputeScaleExt.
System font handling
Added ReportSystemFaceRequest helper to centralize “attach system font or log why not” and avoid repeating the logic at each call site.
Slightly adjusted when system_requested is set and how fallback/system attach errors are reported.
Horizontal layout
sceFontGetHorizontalLayout now logs invalid parameter/handle and, when an external face is present, uses that face’s vmetrics and the per‑state scale to compute baselineOffset and lineAdvance.
(Fallback still uses the simple scale_h‑based approximation.)
Glyph rendering (horizontal)
Reworked sceFontRenderCharGlyphImageHorizontal:
Resolves effective pixel scale from the attached style frame + point/pixel API via ResolveStyleFrameScale.
Uses ComputeScaleExtForState to compute scale_y (and derived scale_x), rather than a single global scale.
Always computes metrics from stbtt_GetCodepointHMetrics + GetCodepointBitmapBoxSubpixel, with metrics->h_bearing_* and h_adv in sync with those scales.
Introduces a clearer origin/gravity model:
System fonts: (x,y) treated as raw top‑left.
Certain external TTFs (EM‑profile) : (x,y) treated as baseline.
Other external fonts (CFF/point etc.): (x,y) treated as line‑top with baseline offset.
Validates surfaces more strictly and returns NO_SUPPORT_SURFACE when buffer/size/bpp are invalid; supports only 1‑bpp and 4‑bpp.
Uses a local glyph_bitmap and a straightforward blit with scissor/clipping, instead of the older mix of cached bitmaps/PUA logging.
Removed PUA/placeholder glyph debug tracing and the more ad‑hoc baseline “adjusted_y” heuristic.
Logging clean‑up
Standardized LOG_INFO/LOG_DEBUG in sceFont* functions:
Info: usually just "called" or a short description (“scale pixel set requested”, etc.).
Debug: "parameters:\n"/"result:\n"/"template state:\n" followed by values on separate lines.
LOG_ERROR messages no longer repeat the function name (logger already prints it); they now say "invalid parameter", "invalid font handle", "no support glyph (face/scale)", "no support surface (buffer)", etc.
Added missing error logs before some early returns (allocation failures, page_count == 0, invalid parameters), and upgraded a few previous LOG_DEBUG “invalid params” to LOG_ERROR where they correspond to an error return.
* Some mprotect fixes
The biggest thing here is preventing mprotect on memory that isn't mapped in address space. This would cause exceptions before, but succeeds on real hardware.
I've also included a couple other minor fixes, mostly based around some tests I recently performed.
Note: All changes to memory pools in this PR are assumed. I have not yet tested memory pools with any of this logic, but I do at least want to prevent mprotect on pool reserved memory to avoid crashes.
* Update memory.cpp
* clang
Added full glyph tracking/outline plumbing plus mutex-protected generated-glyph tracking and helpers (BuildTrueOutline, true-outline extraction, glyf detection, system-font cache/fallback logic, etc.).
Swapped OTF defaults for several JP/JP_AR sets (and CJK sets used by Death Stranding / Anywhere VR) to SSTAribStdB24-Regular.ttf or other TTFs so we load glyf faces.
Wrapped every LOG_* call in INFO/DEBUG pairs: INFO just announces the call, DEBUG lists each parameter on its own line with an extra trailing newline; warnings/errors remain for validation/fallback.
Implemented TTF detection for cache loading and fallback with logging.
Renamed glyph param struct/members, moved glyph handle struct into the header, and renamed the glyph API parameters/fields accordingly.
font.h
Added the new glyph outline/glyph handle definitions and renamed OrbisFontGenerateGlyphParams members (id, res0, form_options, mem, res1/2).
Updated function prototypes to use the renamed types and pointers (e.g., sceFontGenerateCharGlyph signature now matches the new names).
fontft.cpp
Reworked sceFontSelectLibraryFt/sceFontSelectRendererFt logging to follow the same INFO/DEBUG pattern (INFO announces that selection is requested, DEBUG dumps all params).
