"Space Station Silicon Valley" [N64] vs "Evo's Space Adventures" [PSX] ?

SpaceStation Silicon Valley was the original game released for the Nintendo 64. In 1999, the game was ported over to the PSX and titled "Evo's Space Adventures".

How does the latter compare to the former? Is there a significant deviation in graphics, animation style, or gameplay? What about the story or plot of the game?

The reason I'm asking is because I really want to play the N64 version, but it's not very compatible with Project64, so I thought if the PSX port was pretty much, if not exactly, the same thing, maybe that would be more compatible with ePSXe and so I could just play that one.
