i agree its very good for speed, but I mainly wondered if v-sync was possible to be added to the emulator itself, and if so, if the n900 was technically capable of at least constantly maintaining the same speed as it runs at now with v-sync switched on. if you try games that scroll (eg platformers) you may notice the lack of v-sync when the screen moves along (horizontal lines/screen tearing). this is viewable on all similar software, as the n900 does not support v-sync at all. Im hoping it could be added by nokia in a future update, although I doubt they would see it as a major issue.

Nokia pretty much admitted that the n900 was a rush job when they stated that they did not have enough time to add an fm radio (although third party players can now be downloaded), but the general lack of screen v-sync does not boost user confidence either. Hopefully, if nokia refuse to ever add v-sync, then it could be included in third party software instead (such as in emulators where screen tearing is most noticable)... but im wondering if its addition would impact on emulator performance due to the phones technical ability/processing speed, or if its simply a matter of time for the emulation to get to the correct level-if there is much room for improvement.
