Gotcha. I some way expected your answer (I supposed if it was possible you already offered it as .d81 too), but I had to try :-) 
Thank you, anyway.

Just a last question: do you know if is there any hardware project that allows to make a single cartridge for Briley (instead of Kung Fu etc.)?

I mean: (e)eprom based cartridge.

There are some projects on github (like MagicDesk based cartridge with 1 Mb of "storage": https://github.com/msolajic/c64-magic-desk-1024k) that sound interesting, but I'm not sure if Briley would work.

I know that Kung Fu etc. are a modern and easier way to do, but I love the feeling of hard-coded cartridge, one game per cartridge...
