Impressive actually. Putting any such banked carts into an Atarimax cart is non-trivial. The banking is different for starters and each Rom would need to be individually configured to live in specific cart banks. Then a custom Dos build would be needed.
Though given that the groundwork would have been done for recreating the language carts by other means, it would have made it easier.
That said though, just try building a flashcart from the builder software and you'll quickly find that it just won't work and isn't a case of simple drag and drop.
Have to ask though... is there a 128K version around? Or is this using one of the huge SDX builds with all the help files and stuff that needs lots of space?
