Chex Quest (PC) - Angry Video Game Nerd (AVGN) (Cinemassacre)

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.
