OpenMoHAA Vita v0.0.2-vita.2

OpenMoHAA Vita v0.0.2-vita.2

Second experimental pre-release of the OpenMoHAA PlayStation Vita port.

Changes since v0.0.2-vita.1

• Preserves persistent client-effect events across mission transitions, preventing a confirmed use-after-free during later combat.
• Archives stable TIKI model names for transient effects instead of stale renderer-owned pointers.
• Recovers complete saves created by recent Vita test builds when their temporary-model TIKI pointer is missing but the archived model handle remains valid.
• Skips malformed skeletal render entities safely rather than dereferencing a null TIKI.
• Retains the textured-sky, BSP triangle, multitexture/lightmap, transition-cleanup, and complete manual-save improvements from the first pre-release.

Hardware observations

• The first mission completes at approximately 18–20 FPS on tested hardware.
• Natural progression into the second mission works.
• Fresh manual saves and checkpoint saves have been created and loaded.
• The campaign remains playable beyond the first mission, but full-game validation is not complete.

Installation

Install OpenMoHAA.vpk, then place legitimate Medal of Honor: Allied Assault data under:

ux0:data/openmohaa/main/

The VPK can be installed over an earlier OpenMoHAA Vita build. Existing game data and complete saves are retained.

Save compatibility

• Complete saves containing .sav, .ssv, and .tga may be recoverable with this build.
• Older metadata-only slots lacking the required .sav world archive cannot be recovered.
• Some save thumbnails may contain black or noisy framebuffer pixels. This is a separate screenshot-capture issue and does not indicate that the .sav payload is corrupt.

Known issues

• Performance is scene-dependent and can drop substantially during NPC-heavy combat.
• Save/load and checkpoint behavior remain experimental.
• The complete campaign and expansion campaigns have not been validated.
• Occasional crashes may still exist in untested effects or mission paths.

This is an experimental pre-release, not a final stable port.

OpenMoHAA Vita v0.0.2-vita.1

OpenMoHAA Vita v0.0.2-vita.1

First hardware-tested pre-release of the OpenMoHAA PlayStation Vita port.

Highlights

• Correct BSP world geometry through the Vita triangle-surface path.
• Working diffuse and lightmap multitexturing.
• Textured sky rendering converted from immediate mode to Vita-safe vertex arrays.
• Hardened cgame cleanup across level transitions.
• Complete fresh manual saves (.sav, .ssv, and .tga) can be created and loaded.
• Vita-tuned graphics defaults bundled inside the VPK.
• Reproducible VitaSDK GitHub Actions build with symbol artifacts.

Hardware results

• Base campaign boots and plays using retail MOHAA data in ux0:data/openmohaa/main/.
• The first mission completed at approximately 18–20 FPS on tested hardware.
• Natural progression from m1l1 to m1l2a succeeded with the transition cleanup patch.
• Textured sky rendered correctly without the earlier stretched geometry.
• A fresh manual save created by this build loaded successfully.

Installation

Install OpenMoHAA.vpk, then place legitimate Medal of Honor: Allied Assault data under:

ux0:data/openmohaa/main/

The VPK may be installed over an earlier OpenMoHAA Vita build. Existing game data is retained.

Important save note

Save slots produced by older Vita test builds may contain only .ssv metadata and a .tga screenshot. They cannot be loaded because the required .sav world archive was never written. Create a fresh manual save with this release.

Known issues

• Performance remains scene-dependent and can fall substantially during NPC-heavy combat.

• Automatic level-start/transition saves remain disabled on Vita; manual saves are supported.

• Expansion campaigns are not part of the current base-game hardware target.

This is an experimental pre-release, not a final stable port.
