with the app you mentioned its just possible to change the hardcoded 4:3 res in memory.
setting up other than standard resolutions for aquaria is possible by changing the first two values in the init.cfg in the game's folder - just as said before somewhere around here.
too bad it doesnt work as we want it to do. if it did, i'm sure derek and alec would've been thoughtful enough to put other options in the config-app

just seems like we have to wait until our dear devs decide to go for it. guess there are some changes to the engine neccessary, like when (and where) gfx have to pop up on the visible display area etc.
still.. hard to preach patience if youre impatient like me
