How to make clrmamepro scan files >4 GB?

Hi,
like many of you, I use clrmamepro to rename and check my roms/isos. I think my version is quite up-to-date (3.123); I can't check that though since the official page seems to be down. Anyway, I'm having trouble reading files over 4 GB. All my isos are 7-zipped, so the bug might be related to this? When I scan my PS2 folder, for example, I get this warning:
Code: Select all
Corrupt Archive File:C:\Emulation\Dumps\Sony Playstation 2\Champions_E.7z | Reason: NO ENTRIES
Corrupt Archive File:C:\Emulation\Dumps\Sony Playstation 2\God of War.7z | Reason: NO ENTRIES
Both the compressed and uncompressed files are well over 4 GB. Does anyone have the same problem? Are there maybe newer versions of clrmamepro fixing this?

I don't know if they have fixed this problem, but seems that images bigger than a standard DVD5 have this problem even if zipped.

So I'm not alone
Man, I'd love to use RomCenter anyway, if only it could read 7z...

Zip files never supported anything bigger than 4GB
I suspect the 2 files you have are indeed corrupt. Did you try to extract them with 7z directly?

Yes it's different, I had no corrupted images. If I remember well it reports something like "impossible to read central directory", by the way it read checksums.

Extracting them directly via 7-zip works like a charm. The files don't seem to be corrupt - I've dumped and packed the games myself. Also, the problem occurs with all 7-zipped isos >4 GB I have, also the wii ones! This means ~10 files which all happen to be >4 GB would have to be corrupt
And no, I'm not on FAT, I use Vista64 on an NTFS partition.
Good ideas so far, but I guess either clrmamepro or its implementation of 7z is the culprit

Then it would be the best to contact Roman directly and write a 'bug report' on the clrmame forums:

4gb is exactly limit of addressing with 32-bit...
but I assume you are using 64-bit version cmpro64.exe ?
if so, the only solution would be replace lzma compressor within clrmame with newer one that supports large files

I'm using 64 bit clrmamepro and 64 bit 7-zip.

How would I do that? Does such an updated compressor even exist?
