Description:
This patch completely replaces the original engine, adding performance improvements and new features, as well as missing levels from the Jaguar port.
Changes:
- Includes levels that were omitted from the original release.
- Network support via the Zero Tolerance (aka Technopop) link cable.
- Splitscreen coop and deathmatch modes.
- The Cyberdemon and Spider Mastermind have been re-added to the game.
- New title screen that resembles the Saturn and PlayStation versions.
- The iconic screen melt effect for scene changes.
- Rendering has been spread across both SH2 processors for better speed.
- User input is processed at 30FPS, while game logic runs at 15FPS.
- Low (two pixel modes) 128×144, 128×160, 160×180 and three high detail 224×128, 256×144, 320×180 video modes.
- Anamorphic widescreen support for 16:9 screens.
- Mip-mapping for walls and flats.
- Improved visual fidelity (aka 'high color') mode.
- FM Synth soundtrack courtesy of Spoony Bard.
- Selecting between no music, VGM FM music, 32X+, or playing music from attached Sega CD (requires Sega CD in addition to 32X).
- Sound driver that uses the Sega CD hardware to offload sound mixing from the 32X.
- Stereo panning for game sounds.
- Controller hot plugging support.
- Save ram support - keeps track of finished levels, health, armor, weapons and ammo - eight save slots as well as an auto-save at the end of each level.
- Restores sprite directions from the Jaguar version as well as in-fighting between monsters.
- A new port of "Slough of Despair" and level fixes courtesy of Wavy.
- Spectres look the way they did in the original PC version.
- Jaguar Doom HUD assets.
- Three drawing modes: the regular sector based lighting (although it's better than the original Doom 32X in that sprites also use this lighting, no more 100% bright sprites!), "potato" mode which doesn't texture floors or ceilings for slightly better speed, or the original Doom fading light rendering (which is just a smidgen slower and looks a little muddy given the fifteen bit palette of the 32X).
- 'Always run' option.
- Anti-aliased automap with smooth scaling.
- Support for three-button and six-button pads, as well as the Sega mouse. You can choose how to map the primary three buttons in the menu.
- Verified as working on Kega Fusion 3.64, a Model 2 Genesis + Model 2 CD + launch 32X, a CDX + 32X, with a NeoFlash NeoMyth MD and the V1 Mega EverDrive, and also with Mega EverDrive Pro and MegaSD.
