Maybe we should ask the people from encode.ru for ideas for a C-implementation of a blockwise SzAr_Extract function. ;-)

Especially the allocation of memory for the whole uncompressed file is a serious issue. (Nothing bad for files up to 1GB in size for most computers, but for >4GB files it is some issue tongue)

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

well... i think only creator of the software can do that , didnt seen source code anywhere

oh.. and the second question http://www.7-zip.org/sdk.html smile

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

Just did that smile

4gb is exactly limit of addressing with 32-bit...
but I assume you are using 64-bit version cmpro64.exe ?

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

if so, the only solution would be replace lzma compressor within clrmame with newer one that supports large files

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 smile 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 smile

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.

got version 3.118 but dont think thats the case

maybe you are on FAT file system ?

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:

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?
