I've thought about doing that sort of thing (a la MAME32) -- it would be great to have pictures of the cab and a description/history of the game.
It could be added to the current VB loader fairly easily, but I've been holding off on making major changes/additions, since there are a couple of efforts underway to make a cross-platform GUI in C/C++. (The VB loader was never really intended to be permanent; we just needed
something to help people run Daphne. Of course, any code that works has amazing staying power...)
Rather than adding yet another feature that will need to be ported to the new UI, I hope we will be able to write stuff like that just once when the new UI is further along.
Of course, the VB source is in CVS, so if someone wants to add it...
