No. You have a port of an earlier version of their GBA emulator, a port of their video player (not bad actually) and you can also run the port of dingux that it has ( http://filetrip.net/nds-downloads/f...ad-ismartlinux-beta-1-2-full-pack-f25444.html ), the latter is amusing but nothing particularly special happens in it that you can not do with standard DLDI homebrew, sure you have amiga and even some PS1 stuff but realistically none of it all that playable.
I saw ISMM carts going cheap the other year (though seen as it was a realhotstuff endeavour and they are not doing much of anything these days one might be harder to find) and if you just wanted the GBA and video aspects of the DSTwo you can get it done that way. Obviously to run it on a more modern DSi, 3ds or n3ds then you will need http://gbatemp.net/threads/release-use-blocked-ds-flashcards-on-3ds-probably-n3ds-too.376719/
If you just want it for a DS or DS lite then it could be worth it.
