JR has released a new version of the 'c' version of his MSX emulator for Nokia Series 60 phones, which is specifically targeted at phones running Series 60 2nd edition, feature pack 3, with 352x416 resolution display. This version now works as it should on the Nokia N90 phone.
If you have any suggestions or comments on fMSX/S60, feel free to post them in this forum topic. To ease up the installation of this emulator on your mobile phone we recommend you to use Sousuke's ROMpackager.
