Now that i have an original board (Double Axle) i have figure out its just a matter of PAL/GALS because the boards are identical (and they are the last game produced on Z hardware, both 1991).
Unfortunatly i'm not able to copy these and they were removed from jammaarcade (for good reasons i suppose).
The conversion however is 100% possible, but i'm pretty sure i won't find these dumps anytime soon
