Known good sfArk files to test? The ones I tried all fail.

[flintjr]

Hi,
Got some sounds fonts from http://www.thejazzpage.de/index1.html
Very nice jazz midis. Tried out your utility but have no known good sfArks to test with.
This is on Fedora 31 x64. Below is the error and file.
Thanks in advance,
Flint Jr

Here is the file:

On Windows here, I tried building the cpp file with GCC, it complained for a .h header, saw no header in the repo, and found this: https://github.com/moltenform/sfarkxtc-windows which has builds available.

Do you agree to the above terms? (Y/N) Y

Maybe the author did some patches to this fork, perhaps allowing older non-v2 sfArk to decompress?

Here's a couple example sfark files,

If I recall correctly, this sounds like the issue where gcc/clang x64 builds don't work. The size of unsigned long on that platform is 8 bytes, not 4, so the file IO reads the wrong data.

I'll see if I can submit a PR with an assert warning about this, or at least a -m32 in the Makefile to create only x86 builds.

sfarkxtc (in x86 builds) is quite accurate in my experience. In the roughly 11,000 sfArks I've downloaded, only 5 or so couldn't be opened, and these were for unusual cases like .sbk (sf1) data.
