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.
