Asura Blade/Buster Jamma Edge

[Mageta the Lion]

I read somewhere that there is an Issue with the Jamma Edge on those PCBs, something about the Audio Ground being switched, and now have some questions:
1. Is Buster and Blade affected or just one of them?
2. What does that actually mean in practice?
3. Can you just put them in a cab or are you risking damaging the PCB that way? If so what would you damage, the amp or something more serious?
4. Do you need an Adapter to run them? If so is there a plan for one?
Bonus Question:
5. Is there a way to tell Blade and Buster apart visually? I checked fuukifg3.cpp in MAME and they seem to be identical down to the screen print

As far as I know there are some revisions of the Fuuki motherboard that have audio ground switched. This thread covers it:

Blade and Buster are rom boards. If you find a good motherboard you can swap between the two games.

Indeed the Asura blade / buster roms are compatible with the same motherboard

I am lucky enough to own Fullkit which is made up of the motherboard and 2 ROM board

1) same base pcb/motherboard
2) if your audio device is expecting a ground, it's not going to work
3) usually cabs are ok with it
4) you can use something like a jnx atlas and just switch the pins on that
5) they're different rom boards on the same motherboard

Thanks for all the answers. So no danger in plugging in the Pcb just no Sound on all setups? The Adapter just switches pin 10 with pin L?
