JK2 Vita 1.0

Renderer

• No libshacccg.suprx needed. Shaders are compiled at build time and ship inside the eboot
• Native GXM backend — the game draws through sceGxm directly. vitaGL is gone, submodule and all
• Own DXT1/DXT5 block compressor, so the texture cache no longer depends on vitaGL's
• Large textures allocate from CDRAM instead of exhausting LPDDR
• World geometry, skybox, dynamic lights, surface sprites, flares, cinematics and the screen melt all draw through the backend
• Fog runs in the fragment program off the map's fog volume, on the game's own curve, per pixel
• Screenshots and the screen melt read back from the display buffer
• Ghoul2 vertices skin on the render thread
• On-screen keyboard and system dialogs composite through the native present

Menus

• The d-pad drives menu focus, and focus carries the pointer with it, so items highlight and
  activate the way they do under a cursor
• Left and right change a setting's value directly — toggles, multi-choice options and sliders —
  without moving the cursor onto the control

Performance

• Static vertex-lit world surfaces stay resident in GPU buffers, with every stage drawn from them
• World buffers packed in material order
• Vertex uniforms resolved once instead of per draw; fragment uniforms reserved only when stale
• Effect debris and colliding particles sweep across a slice of frames
• Point contents skips brush models the point cannot be inside
• Voice lines load on demand

Memory

• Map-load allocations come from reserved regions instead of the general heap, which cuts the block
  count and peak usage a level change leaves behind

Fixes

• Collision leaf cache was shared across cores
• Textures and world buffers could be freed while the GPU was still reading them
• DXT cache entries are checked against the geometry their header claims
• Out-of-memory eviction and the weather point cache moved to the main thread
• Immediate-mode draws could sample a texture unit that was never written
• Vertex ring and shader registrations survive a vid_restart
• Stale dynamic light bits when a surface entered the view
• Brush check counter was narrower than the count it was compared against
• Region clip could run past the screen
• Console text is printed as data, not as a format string
• NaN is tested by bit pattern, so -ffast-math cannot fold the check away
• The Vita default binds are applied on first run only, instead of overwriting custom binds
• The picmip floor the Vita block documents is actually installed
• Sound uses the stock pool budget
• Async sound reads retry; an unsampled voice line stays marked as playing
• Raw sample path guarded against ring overflow
• The version banner reported the wrong engine name, linux as the platform, and the build type in
  place of the build date

Cinematics

• A frame is decoded when the decoder switches handles, so a cutscene no longer opens on a stale frame
• Video map stages bind their own scratch image
• Stopping a cutscene stops its voice track with it

Removed

• Render-scale path
• r_effectCombine — additive effect stages are folded by the backend's texture env instead
• Prebuilt Windows audio DLLs

Defaults

• Ghoul2 crowd LOD is off

LiveArea

• New icon and start button

Build

• Builds to build/; no vitaGL or SDL install step
• Configuration app and GXM probe are opt-in
• Third-party table and README corrected

JK2 Vita 0.9.82 - Playtest Build

JK2VITA 0.9.82 playtest

Performance

• Static world VBO — world geometry lives in GPU buffers, only indices per frame (r_worldVBO, default on)
• Lightmap atlasing — lightmaps packed into 512x512 pages so world surfaces batch (r_mergeLightmaps, default on)
• Script-authored world shaders now batch too — 88% surface residency on artus
• Inlined the hot vec3 and clamp helpers
• Cut per-vertex work out of the world marshal path
• Vertex range supplied on indexed draws
• 16-bit tess indices

Fixes

• Dynamic lights drew past their vertex buffer
• Console text was treated as a format string
• NaN checks were folded away by -ffast-math
• Fog and lightmap brightness in the world VBO path
• Patch surfaces lost dynamic lighting across a tess flush
• Lightmap seams at atlas page edges
• Render thread outlived window teardown
• Frame buffer flipped on a mid-frame flush
• Level-load teardown freed textures the backend was reading
• Stale pre-skin pointer on recycled Ghoul2 surfaces
• r_picmip floor of 1 was documented but not applied
• Sound pool forced to 64 MB; now the stock 25 MB

Controls

• Default binds apply on first launch only, so rebinds persist. vita_defaultBinds 1 + relaunch restores them.

LiveArea

• Custom launch button, new background

Build

• Single build target
• Version derived from one variable; reports OpenJO: JK2VITA-0.9.82
• Builds from a clean clone with VitaSDK and the submodules

Requirements

• libshacccg.suprx and your own JK2 base/ PK3s — see the README

JK2 Vita 0.9.81 - Playtest Build

JK2VITA 0.9.81

Needs Testing:

• Fixed the Yavin Trial progression issue caused by ICARUS variables not being reset between levels.

Added

• Added optional Aim assist:
  • g_aimAssist 1 — Enable look assist.
  • g_aimAssistPull — 1.5 / 3 / 5 (pull aggressivenes).
  • g_aimAssistSpeed — 0.7 / 0.5 / 0.35 (look speed near a target).

JK2 Vita 0.9.8 - Playtest Build

JK2VITA 0.9.8 — Playtest

Changelog:

• Multithreaded renderer (game / rendering / audio / skinning split across cores)
• On-card texture cache
• Save/load + scripted-progression fixes
• Rain/weather rendering fixed
• Surface sprites off by default (r_surfaceSprites "1" to re-enable)

Test focus: full playthroughs, level progression, save/load (try to break it), stability.

Frame cap — r_swapInterval: 0 uncapped · 1 60 fps · 2 30 fps
