Re: Get Information from experts about Flux transitions

To be honest, what I don't understand yet (I have nearly no hardware background at all so please forgive me if this sounds stupid): Both index and sample clock share the same base, how can there be a drift at all unless both clocks are working asynchronously? EDIT: And from what I have seen so far, ...

Re: Railroad Tycoon woes...

Would you mind uploading the dump somewhere for investigation? May I also ask you to consider generally contributing your dumps as soon as we sorted that issue out? :)

Re: conflict in vietnam trouble when writing-reading

Well, in this case the resulting G64 was enough to demystify the reason for your problems. Do you remember these lines? ;-) In your Conflict Of Vietnam dump there is a write splice before the index hole. This is different to a few RapidLok titles which I've compared it with. There should be one larg...

Re: conflict in vietnam trouble when writing-reading

If sncboom2k made a dump of the very same disk wihtout any trouble, it would be possible to compare his dump with yours to point out the differences and which of them might be causing all the trouble. Some time has passed since I have taken a look at your dump, but it's also perfectly possible that ...

You could also try EditDisk:

Unluckily I can't say what licence applies to it as the readme.txt is written in Japanese, but it seems that this software is free as there is obviously no trial period, expiration or nag screens.

Re: multiple densities on one track

The G64 specification reveals that there is very limited support for multiple densities on one track using some extra data, but this isn't -as far as I know- supported by any emulator. It would lead to conflicting or imprecise information anyway: Density changes must occur on GCR-byte boundaries and...

Re: what to do if you have KF but not nibtools?

My guess is that he means tracks that have sectors placed so that they span the disk index, i.e. tracks that are not index-aligned. G64 needs byte boundaries, maybe he just fears that sectors would get destroyed by placing necessary padding bits in the wrong place.

Re: Anomalous MFM image sizes produced with -i4

Normally they should be fine, however it could have happened that DTC just couldn't even detect the last sector of one track due to bad data, e.g. because sync mark is unreadable. In that case it probably just assumes one sector less per track and ignores the garbage which for us turns out to be an ...

Re: Anomalous MFM image sizes produced with -i4

Please keep the dumping process format guided. Even if DTC performs some (in this case maybe unnecessary due to copy protection) retries due to the errors, it helps getting a track dump with all sectors intact where data is not correctly readable at any access because of the disk being in bad shape ...
