Description

Yume Nikki PS1 is a recreation made by Elias Daler (also developer of Project MTP) of the original Yume Nikki game for the PSX, reimagined with a fully 3D presentation. This is a short (~10-15 min) demo containing two dream worlds.


Extra info

Originally released in 2004, Yume Nikki was developed by the enigmatic creator Kikiyama and quickly became a cult classic within the indie scene. Unlike traditional games, it offers a deeply atmospheric and surreal experience with minimal narrative guidance, encouraging players to explore strange dream worlds at their own pace. Its unconventional design and haunting tone have gone on to influence countless indie titles over the years.
 
The PSX version aims to recreate the original experience while adapting it to the constraints of the PlayStation hardware, translating the original 2D visuals into a fully 3D environment. Despite being an early project, it already demonstrates how such an abstract and unconventional game can translate to the console. 
 
Development on Yume Nikki PS1 is currently on a limited basis, as the developer is primarily focused on Project MTP. Sporadic updates may still be released, mainly adding small improvements or fixes to the game. The last updates focused on performance improvements, bug fixes, and gameplay stability, particularly in more demanding areas such as Snow World.
 
The demo has the following features:
  • Two dream areas (Block World and Snow World) and two effects to find (+2 "pseudo" effects). 
  • You can drop effects in Nexus.
  • Jumping mechanics.
  • Photo mode.
  • And much more!

Elias continues to work with the camera, but has stated the following about fixed camera perspective:
"It looks quite pixely in the original PS1's 320x240. Not quite bad though? It runs *really* slow with this render distance on PS1. (~5-10 FPS sometimes). Turns out, Madotsuki moves *really* fast in the OG. 

This kind of perspective is not possible on PS1, sadly... You can't even have normal orthogonal projection on PS1 due to how the hardware works. So I'll experiment with more stuff, but I had to bump the walk speed on this level to 2.5x (!) to make the traversal not as slow...  

There are to many polys for PS1. If there was no culling, the game would have run out of RAM on the first frame."



Example of the fixed camera perspective with issues


An interesting fact about the development:
"Notice how when Madotsuki uses effect/transforms, she temporarily becomes much brighter (to simulate the flashing in the OG).

Kamakurako becomes bright too, but this is a bug... When I looked at it, I thought "Wait, this looks like dynamic lighting!" and decided to leave it."


Both characters have the lighting effect.

Warning: the game might freeze during the loading process when running from CD-R's.


"Unfortunately, many PS1 drives are slowly dying and can have problems reading from CD-R's. Burned CD-Rs use a different technology of encoding the data compared to the licensed pressed CDs.

If the game freezes during the load for you, try restarting and trying again."



Changelog
