To save my precious Hackvision, relying on the fact that it is very similar to an Arduino board, I've first loaded Hackvision firmware to my 2009, adding A/V connection through this one.
Everithing worked fine, so I've moved to a standalone version of a minimal Arduino (smilar to this one), adding a battery holder and a voltage regulator (similar to this one, because I also wanted to power a connected Wii Nunchuk with 3.3V rather than 5V), and put everithing in one of these project boxes).
Now, my precious Hackvision is free to experiment with.

Since I want to use this amazing TVOut library (composite video output library), I've realized a small circuit following the main directions on the main TVOut page and the good modifications added for the Hackvision board (by nootropic design).
Here's the schematic on a stripboard:
And here's a picture of a realization (using a double RCA connector salvaged from old electronics):
