Re: Upgrade Time: Encounter

I was late in the viewing of this great series. This is fixed now! Very good job Dbug (as usual). There are always a lot of things to learn! Funny to discover the DOKE and DEEK commands! I did not know them. Yet they seem to be present (or their equivalent) on many machines! Shame on me! I also miss...

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

I think that the "lack" of mechanical parts of the SD floppy (no real disk rotation, no moving of the read-and-write head) tends to smooth the performances. As for the results of your mapper (btw good job!), I think the Oricutron emulation of the DISK II part explains that. Since there is no emulati...

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

@iss: Yes, you're probably right. I finally understood what you meant. I'm a little slow, sorry :D
By using the hires memory for decoding buffer, we meet this kind of issue!
So not a bug... a feature ? ;)

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

But I noticed one bad effect - in an undetermined moment graphics mode is switched back to text :?, pictures continue to be loaded but the mode remains text. In ~90% of cases when this happens is the Oric-1 picture just loaded, but I don't think that we can blame this particular picture. Is it poss...

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

Here is a "special build" of my first test (FASTLOAD with all these well known and fantastic images from the Oric scene) with a Track 0 interleaving to be able to load/run on a real machine (I hope and expect!). https://github.com/Archange427/FASTLOAD/releases/download/FASTLOAD_RM/fastload_rm.dsk @@...

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

@iss : very nice job! It's not a surprise that my two previous tests don't work as is on real hardware. Because I used an interleaving to boot on Oricutron. With such interleaving, the other sectors of track 0 cannot be loaded in the correct order from a real DISK II (or a SDFloppy II emulator). But...

Re: Upgrade Time: Encounter

Great job (again)!

The differences between your Upgrade Time: Encounter Redux and the original one are impressive!

Re: Upgrade Time: Encounter

@@Dbug: Thank you for this new video. Great again!

I saw you used -f6 parameter (for PictConv) to convert pictures including those you have drawn by hand.
For these monochrome images, -f6 and -f0 seem to return exactly the same result (as well as -f1!)

Is it always the case for monochrome images?

@@iss: yes 1.0205Mhz was for Apple II but I reused directly (lazy you say?!) the music data file I used for Apple II and frequencies were calculated for 1.025Mhz so I leave these value for the INT. But honestly but I'm not sure that much changes the sound heard :D Thanks for the -2 tip btw! And to c...

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

@@iss: you're right! The most important thing is to do what you like! We are all here just for fun anyway! And there will be - at least - one other person interested in your work because I think the Pravetz 8D with a Disk II is just great! Btw, source code for my second test is now available (https:...

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

AppleWin (https://github.com/AppleWin/AppleWin) is an Apple II 8bits emulator very accurate for the disk access. Could be a lead to follow... But is it really worth it? Seems that the Pravetz8D (with Disk II) is really a marginal machine nowadays even for Oric's lovers... And there are already very...

Re: FastBoot/FastLoad on Pravetz 8D/Disk II

@@iss: thanks for your sources! Btw I noticed something weird when running my two tests with Oricutron: if we let the program runs for more than two minutes, we notice that the loading of the images becomes "linear". And then, he stays like that ad vitam aeternam! In fact, with the interleaving I us...

@Chema: thank you! @iss: I love the way you use the $036D routine to load your own sectors. The RTS at $B800 is pure genius! ;) As promised here the sources for FASTLOAD: https://github.com/Archange427/FASTLOAD .DSK file is available in the release part.
