Available now the tool can now reencrypt any type 1 deco cassettes games with any of the other type 1 dongles (if you can create your own tapes). haven't tested on real hardware but it should work.

- possible to swap dongle and use custom cassette with game reencrypted for another dongle on real hardware.
- many more games playable in mame. many new dumps and info for emulation. also the earlier, the possibility to try more games on real hardware will help emulation.

Tempest: the dongles are mostly different. Type 1 refer to the type of logic the dongle has, but e.g. accross type 1 the dongle prom are different and some of the logic are different as well. Same for type 3.
Type 2 and type 4 aren't encrypted but I'm not sure if you can swap dongles.

FYI i started working on this for a friend of mine
https://github.com/ocornut/decocase
I hacked a quick deco-casette decoder based on MAME data and the aim is to create an encoder so that games could be re-encoded to work with a different dongle. My friend figured out how to create cassettes I believe. May take a few months until everything emerges.

From the visible checksum, at least Super Racing, James Buster Douglas and Golden Axe are final build.
Generally over 80% of them are final builds. For some reason I got much more non-final builds from European sources than from US, I don't know why because I am sure that Europe would come later in the chain.

Based on the pinouts, and pins B21/B22 being grounded I would say they could be unlicensed SG-1000 cartridges.

yes someone has figured out how to make cassettes. I don't have the information myself and presume it will be released along with the new dumps.
