self extracting mame romset exe files

[carmel_andrews]

I recently got hold of a cd/dvd of mame romset v59/60

 

Although i could copy the self extracting exe's over, whenever i try to extract the exe's to reveal the mame rom zips there are errors within the self extracting exe

 

although these self extracting exe's can be opened with power archiver/win zip/win rar etc, i have found that you can't 'repair' the suspect file(s) within the s/e exe's

 

The zip file(s) within the S/E exe's have crc errors or loss of data

 

I was wondering if there is or was a utility (xp compat) or program out there that will repair these self extracting exe files

 

A little tip though, never compress zip files into a self extracting exe (you end up with lots of errors) and more so, never put compressed zip files into larger zip file (again, you end up with lots of errors)

In my experience putting compressed files in a bigger compressed file has not given any problems. You just can't compress it more than it already is (in most cases). I think the blame goes to your files themselves. They probably were corrupted begin with. That or maybe the CD backup went bad on you. I had some cd backups I made where the a file or two where burned incorrectly (giving me crc errors).

 

What works for me is to use winrar for archival backups rather than just plain zips. I get better compression rates and I can create recovery volumes to avoid problems like the one you have.

 

Anyway I once used an utility called Advanced Zip Repair which helped me a few times. I think they are not free anymore so check it out.

Is your WinZip version up to date?

 

And, are the files WinZip or 7-Zip.

 

Both possibilities are opportunities for version incompatibilities.

 

Multiple compression is no problem, so long as you have the right archiver versions to uncompress. It could just be that the DVD media is at fault anyway.

 

In any case, I don't know if MAME supports self-extracting zip .EXEs. I always just use basic .ZIP files.
