Doom 64: Merciless Editon

[Deleted User]

The Merciless Edition patch updates the Doom 64 ROM to the reverse engineered version developed by Erick194 and the GEC Team: https://github.com/Erick194/DOOM64-RE.
This contains additional features such as turning off the 3-point filtering, gradient lighting, and offers a music test in the features menu.
This also updates the default settings.
The default brightness and the sound volume are set to the maximum, the 3-point filtering is off by default, and the features menu is always available to access the bonus options.
Also the RSP microcode was updated to F3DEX2, which speeds up some of the geometry calculations.
Doom 64 did not have much slow down due to these calculations, but perhaps this will allow for more elaborate modifications in the future.
The most unique update is the new “Merciless!” difficulty setting.
The monsters and projectiles move faster, have faster reaction times and attack relentlessly.
