Can anyone tell me where i can find a gameboy emulator and a tetris rom? My gameboy just crapped out on me, and that's really the only game i cared about. I'd really appreciate it if someone helped me out.

We can't tell you where to get roms (being that they are under copyright) but you are free to google at your liesure for them. As for GB emus, the best is the recently discontinued VisualBoy Advance. It emulates the GB, GBC, SGB, and GBA and all of them very well and its quite easy to use (it runs zipped roms, controller config, video filters, etc...).

Also, as an important notice, I am no longer working on the VBA code and I have transitioned it to kxu, who will keep VBA updated and has already created a Linux GTK GUI for VBA.

As far as I can tell VBA will still have updates (thanks to this kxu guy), it's just that Forgotten is... uh... quitting the scene.

something about their hardon for perfect compatibility gives me a ...hardon.

Specially BGB, it's easy to play with it, had far enough options and It's one of the fastest

Use BGB, and that rom can be found anywhere. I know this is redundant but "use a search".
