Re: Experimental very fast tape loading

I could spend a long time testing... Actually it does work on real machines, but not in Euphoric anymore. I think I changed the thresholds a few versions ago, and Euphoric doesn't seem to like them. That's a pity and I don't know why, the values I use should be working according to what I measured ...

Re: HIRES ghost line ?

Back to the "ghost line"... I was thinking it could be used to save/restore, on ROM 1.0, the line that is destroyed by the status line (displayed in the middle of the HIRES screen, when Loading/saving for instance). This brought a thought... Could all this be the remains of an old memory map? I mean...

Re: Experimental very fast tape loading

Ok, 1st tests: the loader is now only 0.63 second long... But is not working yet, aaaargh ;) I could spend a long time testing... Actually it does work on real machines, but not in Euphoric anymore.

Re: OType

I recall I found back some data for this tune, but it didn't exactly match the one in the video. Can't recall how different it was, but I can try and find it back if you wish.

Re: OType

There are many different demos for O-Type, that show the project evolved from different ideas.
You can still get the CEO-Mag issue dedicated to Jonathan, where IIRC I tried to sum up all these, maybe it can help (however I'm not sure I put links where to download them)

Re: Experimental very fast tape loading

I'm currently working at reducing the loader's loading time. It's about 1.1 second and this is a penalty for multipart programs, expecially if they're short. Ok, 1st tests: the loader is now only 0.63 second long... But is not working yet, aaaargh ;) Had to cut it in several parts, it's actually a ...

Re: HIRES ghost line ?

There are also all the "invert" bytes values that could be used... But I mean, technically it can be achived, but for a human brain this seems a bit complicated ;) To anyone willing to dig this subject, another way to begin with could be checking existing known HIRES pictures, and see if they alread...

I like the idea of self-executing image files on Oric! But not just using 40bytes .. what about putting it all in the images too .. ;)
Yep, having data that can be both drawing and executable code is quite a challenge, but could be done? ;)

Re: HIRES ghost line ?

Actually that's funny. That means that by adding and saving a JMP $BF40 right before the Hires screen (in 9FFD), you can make a Hires screen self-executing some code. For instance loading the next part, which avoids a small loader. Other option, adding this JMP at the start of the Hires screen (4C ...

Re: HIRES ghost line ?

I've not tested, but I would assume that these 40 bytes are free to use, like the bytes from BFE0 to BFFF :) It seems so! It's initialized as the following TEXT lines, just not displayed. This rings a bell with one of your pages where you explain the TEXT/HIRES mix mode and in an example, the highe...

Re: Experimental very fast tape loading

Hey, I just realized I completely forgot about checking the tap you sent me! Sorry, sorry, sorry... I'll do it ASAP. No problem ;) Hope it works for you. Tested it fine on 90% of my Oric-1 and Atmos (10 machines, 1 fail). BTW, I realise the idea of killing the HIRES Loading bug is not so useful... ...

HIRES ghost line ?

Hi, The HIRES drawing screen ends in BF3F. The 3 TEXT lines at the bottom range from BF68 to BFE0. What happens between BF40 and BF67? Is this wasted RAM space? Is this line invisible because something like it holds an attribute to switch from HIRES to TEXT? Do you think thiese bytes can be used to ...
