AMNESIA '98 is an audio-visual mod that makes Amnesia: The Dark Descent look and sound like a PS1 game, by way of shader rewrites and map edits, as well as completely remade music and down-sampled sound effects.

Originally this was just something I was messing around with to see if I could create PS1-style rendering entirely with shaders, but I liked the results so much that I figured I'd polish it up and release it in time for Halloween (which didn't work out, but it's the thought that counts). Even managed to rope a friend into redoing all the music for me, which I hadn't initially planned on doing at all, but it makes for a much more complete package.

Currently this only supports the base game. Justine support will only take a bit of work, so that's probably coming soon. Custom stories, however, will require a stripped-down version of the mod, as certain effects require map edits to work correctly (namely vertex rounding and UV warping, which require planes to be subdivided into smaller sections), so those effects need to be lessened or stripped out to work with all custom stories.


PSX Graphics Features:

  • Vertex wobble and texture warping.
  • 15-bit textures and lighting, with Bayer dithering.
  • 1/4 resolution downscaling.
    • This isn't exactly optimal, but was done for simplicity and convenience. Downscaling after rendering ensures that the image is always sharp and has pixel-perfect scaling, and functions correctly regardless of display resolution or aspect ratio.
  • Short draw distances with fog and overly-aggressive culling.
  • Normal maps? Specularity? Mipmaps? Never heard of 'em.
  • Greatly reduced decals and particle systems.
  • Absurdly low FOV.
  • Simplified special effects.
  • Lots of other small things.

PSX Audio Features:

  • All music completely remade using period-appropriate synths and authentic 90s cheese.
  • Sound effects resampled at lower rates.

Installation is a bit involved, but follow the README and you should be fine.

I really, really, really hope that one day you return and finish what was started.

8/10

Very original and perfectly manages to be what it claims. The "remake" of the OST is amazing, and I love all of the bitcrushed sounds and pixelated filter and texture warping. You did amazing work here.

As good as it is though, the blue filter replacing the insanity effect is incredibly distracting and annoying. If your sanity is anything below Crystal Clear, you have a permanent blue VFX blocking your view which ruins the experience rather than benefitting it.

I also find it upsetting you did not create custom themes for the Brute and Suitor. Brute has a different patrol theme, if I'm not mistaken, but the exact same danger theme. Suitor just uses the Grunt's.

The very low FOV does not add to the experience, it just makes it nauseating and headache inducing to play. You added some even lower resolution textures than vanilla Amnesia has, but it seems you didn't finish doing that because only a small handful of things look downgraded and it clashes with the more higher resolution textures.

FINALLY, AND MOST IMPORTANTLY

The custom shaders pack that this mod comes with is incompatible with the most recent version of Amnesia. Areas are extremely dark and it's impossible to see anything. I've had to swap around many shader files from vanilla amnesia in order to get it fixed, and I wish I could've seen what it was originally meant to look like. Luckily, other than the lighting, all the other VFX are here. Weird pixel bloom filter, texture warping, some other thing - However, the texture warping and the "other thing" are completely incompatible with custom stories which is very disappointing... Meaning I have to disable/remove the both of them. At least the pixel filter tied to Bloom is compatible with custom stories. Just a filter.

I had the same problem! Here's how to fix: Go to maps folders, each chapter, and delete the cache files. Very easy, though I didn't think to do this for a couple hours, despite my experience with this game!

Thank you! This fixes not only stuck doors, but also floors that are too bendy and twisty after installing the mod. Also, just searching for "cache" in the game's folder and deleting all results (without the folder) achieved the desired result. Thank you!

This also fixes the warped floor bug if it's still present even after disabling cache loading.
