Re: FT-DOS disk size

Ah, thanks a lot for this! Brillant explanation. So it should be fine, I'll keep trying with other disks...

BTW I tried to test the faulty disk with my Jasmin 2 but it began smoking after 30 seconds of unsuccessful attempts to boot... :cry:
I really know why I prefer tapes ;)

FT-DOS disk size

Hi all,
I'm trying to write FT-DOS on a real 3" disk for someone that bought a Jasmin drive, but I keep having write errors after a while.

I noticed the DSK file is 513Kb big. Isn't it too much for a 3" disk?
Or is it just my real disks, or drive, that are getting old?

Re: Latest version of Tap2Wav?

See there for the latest post describing the modifications: http://forum.defence-force.org/viewtopic.php?f=19&t=1082&p=12487&hilit=wav2taps#p12487 I'd be inspired to do a new relase in the future, changing every tool so they generate 5 synchro bytes at the start of TAP files to prevent any problem w...

Re: Nice Hires screens

Well it seems the most complex Hires screens (thus unefficient compression) take less than 5 seconds to load. If you plan to load small quantites of data, I prefer to rely on the worst case. 8KB in 5 seconds, that's about 1,5KB per second (of useful information, neglecting start / stop bits) (I remo...

Re: Nice Hires screens

My idea is more like something where you read a bunch of data as fast as you can, in a temporary buffer, then run some code that do something with the data, then continue loading. Obviously that means that the tape contains blank sections, which have to be at least as long as it take to process the...

Re: Any easy way to fill certain (closed) area of HIRES screen?

Thanks! I see, same thing that happened with my little site when Geocities went down and I didn't have the nerve to set it up again - except my site didn't have any interesting information ;)

Re: Nice Hires screens

About Bad Apple, being in black and white only would allow us to store only 6 bits instead of 8. Removing the RLE compression would allow a constant framerate. But having enough speed for several frames per second seems impossible to me. Loading something compressed then uncompressing it seems impos...

Re: Nice Hires screens

Thanks ! I don't know Bad Apple, do you have a link? The slideshow has a very small pause between each screen (something like half a second), and of course could be faster if only half a screen is loaded for instance. The problem is that according to the compression, the framerate could not be const...

Re: Nice Hires screens

I think there's a small bug though. It seems Pictconv produces a header going from A000 to BF40 for a Hires screen, which is 1 byte too much (should stop at BF3F). This prevented the next screen to load with my fast routines, as it used the 1st data bytes to complete the previous loading I guess. Ap...

Re: Nice Hires screens

Thanks, converting the screens back with the -f1 option seems to work like a charm :)
