Simon,
I don't own an N-Gage myself so I haven't tested it -- but I have been told that the emulator works well on N-Gage. The only surprising thing is that the emulator icon appears under "Media", not "Games" as it should and like it does on 7650 and 3650.
BTW, in theory you could install the emulator by using your phone's browser to download the SIS file but unfortunately it seems my ISP does not have the correct MIME type set up for SIS files so phone's browser does not recognize the file 
So you have to download the SIS to your PC first and then install it to your phone.
Did you read the small FAQ on my web page? Note that you have to install MSX system ROMs separately, they are not included in the delivery due to copyright reasons. Maybe the easiest way to install the additional stuff (system ROMs and games) is to use Sousuke's ROM Packager utility, the link can be found in this forum thread.
I haven't made an emulator before and I must once again underline that I did use fMSX sources as a reference and the emulator should be considered more like a port of fMSX to Series 60 rather than a separate product. Even if I have put a lot of time and effort to this project and I've changed a lot of things from what they were in fMSX I couldn't have done the emulator (at least not in such short time) without the fMSX sources.
If I would have to compare programming an emulator to some other type of software I would compare it to games, an emulator has similar requirements on the system. I have done professional game programming for some years in the past, but I'm not doing that nowadays. Also I've been working with Symbian OS for some years already so the "neighbourhood" is familiar to me 
Actually, programming for Symbian OS is not THAT different to programming for some other platform. If you are thinking about doing something for Symbian OS I can gladly help but I don't think this would then be the right forum for that 
say JR, you told several times you were a professional game developer. Can you give us a hint, which games you worked on?
I hope you aren't expecting something fancy None of the titles are probably familiar to you -- finnish game companies are not as big or visible as the big players in the business... hmmm... one of the games you might know on PC is called "The Driver" - I did not program that but I coded a version of it for Palm OS - too bad Infogrames decided not to publish it after all...
Hmm... Okay, here's one you can still get from the web I was one of the two main programmers of the snowboarding game (virtually board snowboarding) that we did for Nokia for their 9210 Communicator - the game is available from Nokia's software market.
I was also involved in PC stuff earlier but I guess you wouldn't know anything about those as they were only available in Finland, like a modem hosted turn based multiplayer war strategy game for DOS called Metallic Nations. Oh, something you might know, an adventure game for DOS called Alien Incident - I was not really participating that project but I made a quick & dirty CD copy protection for it
Jr! You know about fmsx/s60 v0.95 when withot sound not paused(system error) and when with sound not save state! 
Fix this bug in new version.
Maybe the GoBoy developers are reading this forum, hehe

Yes I know it has bugs, I'm sorry. I'm going to release v0.96 this week and hopefully fix at least some of the problems.
