Some SNES roms with exact same crc, md5, sha1 not recognised

[mundodisco]

Hi all,

I am organizing my SNES/SFC rom collection, using "Nintendo - Super Nintendo Entertainment System (Combined) (20200214-004443)" dat file (downloaded from Dat-o-Matic, with default options).
Romcenter (v4.0.1) is correctly recognizing 3614 out of 3628 roms.
However, there are 14 roms that, despite having the exact (matching) same crc, md5, sha1 (according to dat file) AND same crc shown in Romcenter AND same crc detected by HashTab (a program / plugin for Windows Explorer), Romcenter still does not recognise them.
Could it be perhaps some issue with snes.dll plugin that Romcenter makes use of?

Namely, if it helps, the 14 files not recognised are:
Cassette Kensaki - NUS-you S Cassette (Japan) (En)
Kaizou Choujin Shubibinman Zero (Japan)
Lion King, The (USA) (Beta 2)
Lobo (USA) (Proto)
Magic Boy (USA) (Beta) (1993-03-03)
Mario Paint (Japan, USA) (Beta)
Mick & Mack as the Global Gladiators (USA) (Proto)
Mr. Bloopy - Saves the World (USA) (Demo) (1994-06-21) (Level 11-G)
NFL Football (USA) (Proto)
Oraga Land Shusai - Best Farmer Shuukakusai (Japan) (Sample)
Super 20 Hab (Korea) (Unl) (Pirate)
Super Fire Pro Wrestling 3 (Japan) (Demo)
Superman (USA) (Demo) (1992-05-25)
Tom & Jerry (USA) (Proto) (1994-07-11)

Thank you very much in advance!
