No, sadly I don't mean the new Special Edition version with new graphics and speech. iPhone owners have been lucky enough to get this version but as far as I know there are no plans to port it to S60v5...
However, with the help of ScummVM, you can still enjoy the 1990 classic on your N97! ScummVM, if you didn't know, is a virtual machine that runs (mainly) games that were written using SCUMM (Script Creation Utility for Manic Mansion), such as many of the early LucasArts adventure games like Monkey Island.
There isn't a "proper" S60 v5 version of ScummVM out yet but it installs perfectly fine on the N97. However, because it was made for S60 v3, there are a couple of issues. Firstly it's designed in landscape mode for phones that don't have screen auto-rotation, so I had to turn off screen auto-rotation on my N97 otherwise it would rotate the screen again and it'd be unplayable. Secondly, there is a little grey box in the top-right corner that is always there. Pressing this opens up a simple onscreen keyboard (and cleverly squishes the game screen to one side so you don't miss anything). This is useful for most other phones, but I would like to see a native v5 version come out that supports the N97 keyboard.
Nonetheless, it works fantastically well! You can download ScummVM completely free, but you need to own the games if you're gonna use them on your phone. Thankfully I'd bought the Monkey Island 1+2 PC CD-ROM years ago so I copied the necessary files from that to my phone. Sadly the music didn't play but that's because the music was actually burnt as audio tracks on the CD. Bummer!
The touchscreen works very well. Wherever you touch, the mouse cursor appears and makes the character move to that position, and you can simply tap the on-screen buttons to select them. I would like a new version of ScummVM to replicate pressing the right-mouse button by maybe double-tapping the screen, but you can still play the game without it.
I've got other titles on CD that would work with ScummVM, so I'll be trying those out in due course.
Anyway here're a few photos I took for you all to see:
