This is your set.
Oh ... I thought it will be a more general thing ...
Not the sega converter itself, but the capability of EnterMice handling the sega thing ...
So if there would be games handling the sega thing, everybody with an EnterMice could be able to get a sega converter easilly ...
EnterMice is a more complex thing (with the mouse and even the joy emu) like some "button", but how it seems,
it will be available with enough instance by you, and it will "stand up" some kind of "standard".
In the mouse perspective, it uses an older standard, but sega controllers had no standard on the enterprise formerly ...
and EnterMice (because of the number of the instances available) could be able to stand that standard up ...
But (how I understand you) it will not ... too much ... will it ?
Adapter for you as free. In return for a good idea
Backing to the current instance of the sega converter: do as you wish, but (in this case) I definetly would be able to assembly an instance of it by myself, so it is not a requirement ...
