Re: Oric DSK Manager

Build from sources worked for me. There are problems with few images, but most probably the images are bad.
I like the possibility when dropping more images to merge their content. Nice structured application.
Well done!

Re: Development of Blake's 7 (was OASIS development)

Attached is the quick hack writedsk2f (source & dos executable). It should always format tracks before writing. It's only proof-of-concept. I agree to wait Fabrice's approval for any further releases! Also having always-format as option is very good idea. In source is implemented a workaround which ...

Re: Development of Blake's 7 (was OASIS development)

... the interesting part: writedsk2 first tries to write the sectors and if the operation fails then it formats the track and repeat the writing... He, I was close in my guess, "just" my conclusion was wrong :). Anyway, it's easy to change writedsk2, so it always first formats the track with the in...

Re: Development of Blake's 7 (was OASIS development)

Chema, what model is your Oric floppy? Else I guess you are using Silicebit's controller, right?

Re: Development of Blake's 7 (was OASIS development)

This is great! Thanks, Dbug. I'll check the news and will do test with real HD/DD floppies asap.

Re: Development of Blake's 7 (was OASIS development)

Thanks for the image, Chema! Things getting more mysterious for me :)... But first sorry for my bad suggestion in my previous post, that FloppyBuilder doesn't implement interleave - I wrongly mixed the 'geometry' value with the 'interleave' - they are completely different things. I compared your tes...

Re: Development of Blake's 7 (was OASIS development)

@Chema: May I ask you for the image file with interleave 5, which you used for test? I want to repeat your tests with and I can do some low level analyse on PC to see how different are the HD/DD floppies.

Re: Development of Blake's 7 (was OASIS development)

Ups, the SVN version of FloppyBuilder has code which deals with sector order (I have to update my OSDK :oops: ).

Re: Development of Blake's 7 (was OASIS development)

I am quite sure that writedsk2 writes the sectors in the order in which they are stored in the dsk image, which is with the interleave of 5. Agreed, sectors are written in order as stored in the image file! But FloppyBuilder (all versions) doesn't use interleave param to re-order sectors when build...

Re: Development of Blake's 7 (was OASIS development)

Very interesting case! In my opinion the magic here is the interleave, but NOT the one you specified as parameter (i.e. interleave 5)! From source of writedsk2 it's obvious that parameter 'geometry' is not used at all. And here comes the interesting part: writedsk2 first tries to write the sectors a...

Re: Experimental very fast tape loading

Hm, this is interesting and I think you are right about the bad values in decompression - because bytes are looking somehow shifted but they still 'hires-correct' bytes :) i.e. there are no strange or wrong colors and pixels. I looked in Fabrice's chronometer source, but it's very specific to his Ta...

Re: Experimental very fast tape loading

Symoon, your code is really nice! I expect in final version you move it in to stack instead of $400. ;) About the values: in my experiments with smart phones I found that most of them simple can't play wave forms with only 3 samples (no matter of sampling frequency 44k1 or 48k). This is a hardware l...

Thanks for the game! I tried it and indeed the control seams bit difficult for me too.

Re: Experimental very fast tape loading

Downloaded, tested ... and here is the result: 20180304_145312.jpg As you can see the are some transfer errors, in my opinion bytes are skipped from time to time. Else, congrats it's really fast! The only conclusion that I can make is: player need to be "top quality" :). For playback I used my TapOr...
