Non-converter Gyromite carts: useful for anything else?

[Terminusvitae]

I came across a bundle of five 5-screw Gyromite carts today and after snatching them up (for other reasons, too) at a kick-butt price, I did a quick check and saw that there was no converter in any of them (the pins' flares are all centered instead of offset).

I'd hate for these things to go to waste, and given how common they are, it's unlikely I'd ever succeed in selling or trading them, never mind trying to turn a monstrous profit. So, that leaves something like having a stock of carts for repros, but it doesn't seem there are too many games of ANY stripe that can be burned onto such an early chip.

Is there anything else these can be used for aside from soldering practice? Is there much of a demand for completely empty and de-labeled cart shells?

Keep them, you will inevitably run into a donor cart with a crappy shell. At one point I had to buy two games just to make one decent looking repro because of unique donor requirements.

That's a good point. Actually, that reminds me that my copy of Wizards and Warriors 3 is pretty battered and abused. I can print up a new label and slap it into a Gyromite shell and still have fodder left over.

I used precisely what you speak of-- a failed attempt at converter Gyromite-- to turn my incredibly beaten-up Bubble Bobble into a fairly good-looking copy.

I always use time a dozen and cheap-o extras for replacement back shells.

Can always use an extra that has the gold identifying the cart that has a battery inside.
