Got any update on the svcplus, svcplusa and svcsplus for the lates Mame source 0.103u3. I already gotting the svcboot update that you post. Works like a charm.

I found the svcplus, svcplusa and svcsplus from the mame32-plus-special-0.103u2b-src. But I think those are pointing to the svc and not the bootleg from that source. It wrong and outdated.

I came back here to check and I saw your is correct on the old source again. I don't know if it will the work on the new source. That why I seeing that you have updated it and shorten those down.
