It has been said on the RGP forum that the only difference between the Judge Dredd L3 and L1 sound roms is that in the L3 version they no longer say "Dimensional Lock # is lit" and instead says something like "Dimensional phase". I am in the middle of restoring my JD and was curious to see what I had in mine. Curiously I found the following:
U2 = L1 EPROM
U3 = L1 EPROM
U4 = ?? ROM
U5 = ?? ROM
U6 = ?? ROM
U7 = ?? ROM
U8 = ?? ROM
U9 = ?? ROM
So, in mine I clearly have L1 roms in U2 and U3, however U4 to U9 are all non eraseable, non-rewritable ROMs with part numbers 5341-13812-U# on them and Williams copyright. I dumped all of these chips and compared the files to those available on the internet, e.g. the sound files bundled with the L-7 game rom on the IPDB. My sound files are identical in all cases to those on the internet. I also found on Planetary Pinball's website separate downloads for the U5 and U9 sound roms. I downloaded those and compared them to those I had dumped and the IPDB roms and they are also identical. So are these all L-1 roms? I am assuming that they are.
So where are these mystical L-3 sound rom files? Are they anywhere online?
