It does not use SDL. All video, audio, and input are implemented directly against the Vita system libraries. Music is handled via OPL3 FM synthesis using Nuked-OPL3. The result is a standalone VPK that runs Chex Quest (or any compatible Doom IWAD) natively on the Vita.

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.
