Description

The latest MAME 2003-Plus database update from Nov 27, 2018 makes Retroarch leave out some of my roms. The previous version (initial database) worked perfectly.

For the valid ones left out, torrentzipped file CRCs are :

Filename File Size CRC32
aburner.zip 717.919 fcb29e7e
finalap2.zip 2.167.299 5ada7258
pacman.zip 10.925 368f99b9
simpsn2p.zip 251.134 d7829dd9
tetris.zip 138.007 22ff0eac

Note: romsets validated with latest core-generated DAT from today (Nov 28, 2018), in Romcenter.

Research direction

Compare the Nov 27, 2018 MAME 2003-Plus database commit with the previous database version, using the listed ROM filenames and CRC32 values as reproduction cases. Validate the sets against the latest core-generated DAT in Romcenter and determine why the five valid ROMs are omitted; done means the affected ROMs are included correctly without regressing the other entries.
