I've reverse-engineered the FX-BMP port, and now I've built a cartridge to use it - the PC-FX nvBMP !
This is a FX-BMP replacement which doesn't need to use batteries. The original ones are actually REALLY expensive on eBay etc., although with the semiconductor shortage, this cartridge might not be all that much cheaper... although it won't need batteries, so it won't mysteriously lose your data when you aren't looking, and you won't find corroded battery junk inside in a few years' time.
Additionally, the FX-BMP is a 128KB cartridge; this one can accept larger memory chips if you so desire (and can afford them). MRAM (magneto-resistive RAM) chips are in use here, which are available in 512KB and 2MB sizes as well.
The GitHub repository is here, and includes all the plans including designs for an enclosure which can be printed on a 3D Printer::
Sorry, I won't be doing that - besides parts being hard to find, they are a bit time-consuming to make if any part of it has to be done outside of the PCB factory. Plus, shipping anything from Canada is just miserable. But with the plans up on GitHub, I'm sure somebody will do it...

tron: I hate strictlylimitedgames jash even more so when they get the rights for physical release of anything by taito.

spenoza: It occurs to me that this same limited physical release approach has hit other hobbies as well, like tabletop role playing games. Companies in that space that aren't Hasbro are all small and so they tend to do limited prints of books and then lean on pdfs.
