In case information about DOSBox compatibility is wanted, we could provide a link to DOSBox's game list in the following form.
http ://dosbox.sourceforge.net/comp_list.php?search=${title}
Direct linking wouldn't work unless we record the specific game IDs used by their database. But this can be handled by the related links thing (if it's ever implemented) anyways, so I'm not sure if this is of any use.
I have two way to do this.
For ZX Spectrum games I build dynamically the link to the WorldOfSpectrum search page, instead with LemonAmiga (and soon Lemon64) we preferred to store each game id to provide reciprocal direct links (I had a good success when matching the two databases).
With Dosbox I think I could use the first method with all the DOS games.
Direct linking seems to be of the following form:
http://dosbox.com/comp_list.php?showID={game_id}I don't know their game id. Optest for linking their search page.
