I've downloaded NMIT 4.0 and, as I understood - according to some messages of yours in those discussion boards - NMIT 4.0 doesn't support JPG format.
The question is:
Is there any NOKIA 6600 emulator, which supports JPG?
Actually, I got to develope a website, which fits in that device and I'd really appreciate, if there would be some tool emulating 6600, that I can really use on my PC (with all the features, that 6600 has).
