Hi, I started from a full 0.95u2 split rom set.
I decided to merge it rebuilding it but now, scanning it, i have this log:

Area 51 (Time Warner License) [folder: area51t - parent: area51 - size: 2mb]
wrong merged ROM set: C:\Mame32\roms\area51t (merge to: area51)

Gauntlet Legends (version 1.2) [folder: gauntl12 - parent: gauntleg - size: 544kb]
wrong merged ROM set: C:\Mame32\roms\gauntl12 (merge to: gauntleg)

Judge Dredd (Rev B Nov. 26 1997) [folder: jdreddb - parent: jdredd - size: 768kb]
wrong merged ROM set: C:\Mame32\roms\jdreddb (merge to: jdredd)

Vapor TRX (prototype) [folder: vaportrp - parent: vaportrx - size: 544kb]
wrong merged ROM set: C:\Mame32\roms\vaportrp (merge to: vaportrx)

I tried to cancel area51.zip all area*.zip in Mame roms folder e rebuild it from the original split rom but error is the same.
I opened the merged rom of area51 and inside there are all the file that it is in the split roms.
Any suggestion?
Thanks a lot
