Thanks very much for these, I definitely will be using them (the layout may well be out, by the time you read this), as the sound is now complete. It doesn't seem to like meters set to sec, with sec 1 and sec 2 set up, but still works with sec no, and in meter 1 and out meter 2. I had already got the binary set.
Ironically on the first feature board, I immediately got Find The Pea and yes the sound missing, was causing the feature not to play properly, it's now working fine.
Vecs, the £5 jackpot roms, won't have complete sound and now having played this with and without complete sound, the sound is important in several areas. If the complete roms for the £5 version turn up, then I will at some point do it I guess.
