You're right, but even the Pandora version has some game specific fixes and 2 versions of the graphic plugin, the N900 version didn't have.
Javispedro did some port for the N950 for some times, there is a YT video, but even this version wasn't released for public.

I've bought again a N900 after 2 years, only for the emulators.
Source for Mupen64plus - Android Edition is out since some times, runing @ version 1.99.4. Core version 1.99.5 comes out in a few days.
Stradian from Openpandora.org tries to port the new mupen version, but no news since weeks.

Good news is that Paul Lamb, the developer of the Android port gets a Pandora in a few days and he promised to rearranged the source to make porting easier.
It needs only a good Maemo developer to port it to N900.

Anyone out there ?

One good thing is, that the N900 version didn't have a bug for Zelda - Majoras Mask, the Android and the Pandora have.

A short teaser of the bug, I've made some days ago.
