OK i understood the problem. My sets are merged, and there was a weird folder in the zip containing a deprecated rom.

EDIT : Ah ok, i found a weird collision for roadblstgu\136032.107.b2 (CRC : 7a29dc07) (which is 136032.104.f5 (CRC : 7a29dc07) from the atarisy1 bios rom)

and

136032.107.b2
(CRC : 315e4be4) from atarisy1 bios rom, which is a different rom, with a different CRC.

An error from MAME ?
