Of course, feel free of using/abusing any code that i have published.

@SyX:

Your script is now added to the cd32tools repo with the changes already discussed in the thread to get it working. Also made it use external trademark file so nobody complains.

Actually, now with the fully working mkisofs-isos I retried the boot time. When I did the previous timing I was under the impression it created correct isos for me as it did boot and appeared to work fine.

However, it did not and this affected the boot time. We use ahx music in our menu and it looks in S:ahxWaves.location for the path to the precalc data and we have that data in S:ahx.waves. Our Startup-Sequence had uppercased first character in the name, with the result that the CD32 couldn't lock either of the ahx files leading to it precalculating it with the cpu, which normally should be slower than loading it from disc. However, with the mkisofs generated iso it apparently is slower reading from file :P.

We have also made one change to the CD, we now run "C:SetPatch QUIET" first in the Startup-Sequence. This makes the measurements a bit non-consistent with the previous. One insteresting thing with it is that it actually made the ISOCD-generated disc boot even faster than before. SetPatch says it patches a "cd CD_SEEK" function, maybe that is beneficial?

Also for fun tried a depth first sorting with the per-directory file sorting on upper case names manually removed and without prioritization list using generateLayout.py. Just guessing that that is something similar to the order of makeisofs.

Nevertheless, these are the current results.
Mkisofs: 17.88s
ISOCD with depth first, no per-dir filename uppercase-sorting: 17.34s
ISOCD with regular breadth first with our prioritization list: 11.64s

Ok, we can keep both solutions. The slow one will be for day to day builds to test on emulators, and the ISOCD one will be for releases.

Indeed, just wanted to update the numbers and was also a bit intrigued by the positive results by running setpatch. If anything, I expected it to get slower as it is one more command to execute. Did not expect it to go the other way.
