Quoted from emkay:Out of curiousity, does anyone know if Rottendog pays any royalties on these repro boards or is the IP generally considered to be in the public domain? Only asking because I was surprised by how much they charge.
If Rottendog was playing royalties, the boards would be coming with holograms from Planetary.
The ASIC chip on Rottendog's A/V board, for example, is an original WMS part. He hasn't taken WMS code and made his own part - he's using factory parts.
The other ICs are parts from the original MFGs (not proprietary Bally/WMS code), and their use would not be of interest to Planetary.
Rottendog does indicate his boards are redesigned, so it's not a 1 exact clone - probably allows him to avoid royalties.
The boards don't include ROMs, so no WMS specific code is included with them.
