Hey Lee, just wondered what you mean about the s-video output of the supergun being "mediocre to good"? I've been considering getting a supergun for a long time, already have a nice little batch of MVS games, but haven't quite taken the step yet . . . I pretty much know that sooner or later I'll buy a complete good condition 4-slot dedicated cabinet, but the supergun would be a nice option . . . to play my MVS carts on my 27" TV.
Oh, and also, is your one slot MVS board the older kind with joystick ports on it? I understand that the new 1-slot boards (minis?) don't have any joystick ports . . only the older 1, 2, 4, and 6 slots.
And I almost forgot, isn't the 4-slot MVS board a MONSTER in size? It looks pretty huge in all the pics . . .
