This is one of my favourite adventure games ever. I prefer the NES port over the others because of it's wonderful music.
The game also was ported to Game Boy Color featuring improved graphics, so if the graphics really hurt you, grab an emulator and try this verson or the NES one. Deja Vu deserves to be played.
Also there are windows ports with improved graphics of both Deja Vu games. I can upload them.

I can't run this game in dosbox!
I tried the set of the dosbox.config but it doesn't start.
Please, help!

And? Details please (your mount commands, which file did you use to start the game, any changes in DOSBox conf, DOSBox version, OS you're using, ...)

I can't reproduce the problem, the game seems to work with pretty much any settings and mount commands with DOSBox 0.74.

Maybe your download was corrupted somehow? Try redownloading it and see what happens? Also, are you using a .bat or a .exe?

Available at Steam
 

This is another old game that Steam has claimed from abandonment.
