50-140g.007,50-144g.012,50-145.014,ic10 (same of Olympia set)
g-0960-54.ic15,g-0960-55.ic16 (same of original Rock-Ola set)
nora_2,nora_3,nora_8 main program;
sk4_ic51 (same of Vanguard set)
g-0959-43.ic51 (same of original Rock-Ola set) sound program;
nora_10 (this file could be corrupted, since I suspect that EPROM is faulty), nora_11 graphics.


This romset comes from a Vanguard pcb conversion.Differences are:
Copyright string,one sound rom is the same of Vanguard set.Partial musics and sfx are used in.


update 20170816 from OSSO:
Direi che le due GFX ROMs sono state dumpate a metà dimensione e che nora_8 é un sicuro bad dump.
nora_10.BIN g-0960-57.ic50 [2/2] IDENTICAL
nora_11.BIN g-0960-58.ic51 [2/2] IDENTICAL
nora_8.BIN FIXED BITS (11111101)
Le rom del sonoro sono anche strane: ci sono due ic51, una da Pioneer Balloon e una da Vanguard.
