i have 2 strange super famicom cartridges that seem to have been part of a sfc development kit that was probably meant for amateur use, similar to the yaroze playstation.
however, theres basically no information available on the net, apart from
a patent filed by nintendo:

this is what the system should have looked like:

heres a short outline of the machines features:

pretty cool imho.
i'm in a hurry, but i suggest you read the full patent, its very detailed and interesting, most of the hardware stuff is explained in every detail. my cartridges, for example, are absolutely identical(my carts dont have a led soldered in, but theres a place where a led can be soldered in) to the schematics shown in in the patent:

the carts consist of 4mbit backed up sram to store games plus some glue logic that handles the data upload.
the carts dont look like prototypes, the label is nice and glossy like normal retail carts, so this thing must have been in production, yet i've never seen it anywhere.
the best thing is that one cart contains a game.
it really looks like an amateurs work in every way.
the code accesses uninitialized wram areas(probably depends on the system to initialize those) and the graphics are crappy.
with some hacking here and there, i managed to make it boot to the title screen:

i assume this means asterix no daibouken - big adventure of asterix
anybody seen this thing before or knows anything?
ricky? =)
