Unsupported in IPF

Let me explain something i have discovered, and that happens also on Amstrad CPC that will allow people to understand the analogy :

The SPS encoder has a sort of library for the protections that you can meet when analysing. It works nicely on many softs, but it has a drawback.
On some earlier release of games on the CPC, you have some title that use a specific speedlock protection track, but the SPS tool is not able to recognize the protection properly, when on later titles using the same protection, the SPS encoder recognize the specific version of the protection.

what is the root cause of that ? The explanation is very crude : the protection has been written blindly from the master disk without description. This type of protection need to be descripted in term of format. But here, probably because it was faster and less expensive, the operator simply wrote the speedlock without describing it properly.

Same protection, seen differently for this reason.

This is the exact same problem with Road Blasters on Atari ST. It SHOULD BE recognized as "MFM\Weaksector" in the SPS encoder, but since they wrote it in "blindly mode", i get instead "MFM\9x512, 97,77777%", which means the weak sector is not only not recognized, but the track also doesn't resolve properly with 0,333333% not recognized either.

A solution would be to "FORCE" the parameters on the Weak Sector track, but the SPS encoder doesn't allow me to do that.

So for me, at the moment, it's "unsupported".
