Doom 64: Doom 64: Merciless Edition II

Merciless Edition II is a modification of the reverse engineered Doom 64 source code, with the goal of adding new features and accessibility options. The primary focus on compatibility is Nintendo 64 hardware, but it works on emulators too. Some of the features include texture filtering modes, extended brightness, dithering, colored HUD, automap stats, optimizations, bug fixes, and more! On top of that it has a "Be Merciless" difficulty mode which makes the monsters more aggressive and unpredictable, but gives the players a boost in terms of ammo and weapon switching. Intended for an overall more violent experience for those who dare.

List of Features:

- New "Be Merciless!" difficulty makes the enemies more relentless, unpredictable, and agile. The player gets some boosts too!
- Menus have been reorganized for easier access, new defaults, and to accommodate the new extra features.
- New autorun and motion bob options. Motion bob can be disabled to reduce motion sickness and autorun helps with movement speed.
- Video menu now allows texture filtering, dithering, and interlacing to be turned on or off. Also the game's brightness is extended.
- Display menu can turn off flashes and strobe effects, intermission texts, or new map statistics in the automap.
- New options for a HUD colors, transparency, and margins.
- There is a new "Retro Fighters" controller option and weapon switching has been adjusted.
- Story screens have been updated with a new introduction, ways to speed them up, and grammar corrections.
- Messaging system now supports colors and more lines. It is easier to notice secrets and new death texts from the community appear!
- Game saves now display the difficulty level of the save. Also the difficulty can be changed when restarting a level.
- Missing zombiemen sounds have been restored as well as a some missing texts.
- Features menu contains more options added from Doom 64 RE and a few new bonus ones as well.
- Code has been updated with a higher compiling optimization and updated rendering microcode.
- The new options are tested to work on N64 hardware, however emulators do not have support of all of the N64 features.
- The github page further describes other changes as updates.

Doom 64: Merciless Edition II

# Installation and Description

Merciless Edition is for Nintendo 64 hardware (using a flashcart) or Nintendo 64 emulators. It requires a ROM of one of the Doom 64 release for Nintendo 64, where patches are provided here to upgrade it to the Merciless Edition. You can apply the appropriate patch to its respective ROM version using one of the websites below:

This is a fork of Doom 64 RE where new features for Doom 64 are implemented with the goal of maintaining Nintendo 64 hardware and vanilla gameplay compatibility. Here Doom 64 RE is a complete reverse engineering of Doom 64 by Erick194, which has provided the pathway to achieve such modifications. This branch is primarily hardware focused, however emulation compatibility is still a goal. The full list of features and source code can be found on the github page.
