Port of Chex Quest (1996) to the PlayStation Vita, built on top of the doomgeneric source port of Doom.

A PSP version is also available: Chex Quest PSP.

Features

Native Vita backend (no SDL), with video, audio, and input implemented directly against Vita system libraries.
OPL3 FM music synthesis via Nuked-OPL3.
Supports chex.wad, doom1.wad, and doom.wad as fallback IWADs.
Quick save/load functionality.
Dual analog stick controls.

Installation

Requirements:

PS Vita or PSTV running HENkaku/Enso (firmware 3.60-3.74).
VitaShell.
chex.wad (the original Chex Quest WAD file).
doom1.wad and doom.wad are also supported as fallbacks.

Instructions:

Download the VPK from the Releases page.
Transfer it to the Vita and install it using VitaShell.
Place your WAD file at ux0:/data/chexquest/chex.wad
Launch the game from the LiveArea.
Save files and debug logs are written to the same directory.

Left Analog - Move

Right Analog - Turn

Square or R - Fire

Triangle - Automap

Circle - Strafe Modifier

Start - Menu

D-Pad Left/Right - Weapon Cycle

Known issues

Music is simplified: only 9 OPL voices, single-voice instruments only. Two-voice GENMIDI patches are not rendered correctly. Music sounds noticeably different from the original PC version.
Pitch bend is parsed but ignored. Notes play at fixed pitch regardless of MUS pitch bend events.
No gamma control (usegamma is hardcoded to 0).
Nearest-neighbor scaling only. The 320x200 framebuffer is scaled to 960x544 without filtering.
No external controller or mouse support.
If no WAD file is found, the game logs an error and exits after 5 seconds with no on-screen message.

Changelog

v1.0

First Release.
