Quoted from oga83:
I've been working on this for a while and I still have a lot of work to acheive it.
Pinball Browser is already able to open WPC firmwares and display the DMD frames (since v4.00) but there has been very little interest in this feature.
I'm actually quite interested in the WPC side of things, and will donate if more work is done on that side.
(One thing with the already-implemented DMD frames - locking on the "Group With Next Image" checkbox, so that while scanning through animations it's not required to re-check it each time a frame is advanced.)
