Hi Roman,
I ran into this little weirdness while scanning/fixing the split and non-merged sets.
The zipfile revx.zip contains 4 duplicate ROMs that exist in the zipfile with different names.
"revx.u51" CRC(9960ac7c) SHA1(441322f061d627ca7573f612f370a85794681d0f)
"revx.u52" CRC(fbf55510) SHA1(8a5b0004ed09391fe37f0f501b979903d6ae4868)
"revx.u53" CRC(a045b265) SHA1(b294d3a56e41f5ec4ab9bbcc0088833b1cab1879)
"revx.u54" CRC(24471269) SHA1(262345bd147402100785459af422dafd1c562787)
In the 0.249 datfile, these 4 files are being renamed, but same files are already present in the zipfile with these name.
The clrmamepro (4.046b) scanner (all fix options enabled) shows an error that it failed to unpack revx.u53 and revx.u54.
The zipfile test OK and I can unpack these files with no problem.
This commit makes the changes:
https://github.com/mamedev/mame/commit/23c7f300965c5ea374ff0aad9d58d74c14f18961Any idea what's causing the scanner to produce these errors?
Files to reproduce attached.
With kind regards, NU.
