Title: TEKKEN: DARK RESURRECTION (PPSA31371)
Content version tested: 01.000.002 (PSPHD emulator running the PSP title ULUS10139 v1.00)
AnyPS5 commit: main at 9d6adeb, plus the open pull requests below
System tested: Windows 11, WinLibs GCC 15.2.0 (x86_64-posix-seh, ucrt, r7), RTX 5090 (NVIDIA 610.47), AMD Ryzen 9 9950X3D
Furthest point: In game
What is shown: The intro movie plays, then the PSPHD start screen, the game's start menu, character select and the fight tutorial. Fights play at about 55 fps (judged by eye while playing, not measured from a log).
Current blocker: Nothing stops the game, but these are wrong or awkward (all seen by eye, none investigated yet):

• The PSPHD emulator's own menu (opened with the touchpad) draws its text on the wrong lines. The game's text is fine. This looks like what fix(libSceFont): keep horizontal writing on a single baseline #5209 describes for horizontal writing in sceFont; I have not tested that PR on this title.
• Black triangles move on the ground, and some triangles are missing from the characters.
• PSP START and SELECT are the right and left halves of the touchpad. On an Xbox controller the only way to press them is Tab and Backspace on the keyboard.
• With the vector window narrowing from 30fab07 on, the game stops advancing at frame 23 or so for more than 10 minutes. Backtraces taken during the stall show the NVIDIA driver's shader compiler busy on one mesh shader, and its cached SPIR-V is 4.2 MB. APS5_NO_WINDOW_NARROWING=1 avoids it, and every run that reached the game used that variable. A proper fix is not written yet.
  How it was run: eboot.bin and its modules were relinked with --windows --module-dir ., app0 points at the dump, and the game's play.env has APS5_NO_WINDOW_NARROWING=1. In PSPHD's settings, --has-shown-start-select-help was set so the touchpad help screen is skipped.

Open pull requests applied for this run:

• fix(libSceFont): render a glyph into a zero-extent surface to measure it #9992 (zero-extent render surface for glyph measuring). Without it the title stops with Could not get surface summary (8a6c000b).
• fix(libSceFont): resolve a default string direction at creation #10021 (a default horizontal string reports left to right). With fix(libSceFont): render a glyph into a zero-extent surface to measure it #9992 alone the title stops at the same place, because it passes the string's writing form to sceFontCreateWritingLine, which rejects the default form. Both are needed.
• Noto Sans fonts (including NotoSansCJK-Regular.ttc) in the title's anyps5-fonts folder.
