WonderSwan Best Micro SD card adapter/Flashmasta clone

[Ezri_Muldoon]

So I purchased both a NeoGeo Pocket Color & a Wonderswan Color with the intent of fully upgrading both systems.

Despite Flashmasta's official carts & IPS Backlite kits being out of stock I managed to get clones from AliExpress that work well for my NGPC.
I've also got a a cloned IPS Backlite screen on order for the Wonderswan... But I can't track down a flashcart.

Does anyone know where I could get one?

I know AliExpress sells pre-flashed cartridges of the various fan translations for some games. They're surprisingly affordable but not every title is supplied.
Then there are clones of the old Wonder Witch development kits which are objectively awesome but sell for a horrendous amount. Is there really nothing else?

I just want to play the translated Digimon titles on authentic hardware and I wasn't expecting for it to be such a struggle
Back when I started this project in January Wonderswan flashmasta clones were listed on Aliexpress but they've all been struck down by copyright claims.
(Which is something I wholly support)
Yet Flashmasta hasn't replenished their stock since the clamp down on the clones so am I just out of luck.
