Thinking now I might 'cheat' a bit and align all pop-ups to the complete right of the screen. At least in that case I do not need to worry about the attributes being incorrect to the right of the pop-up, sparing me the space needed to set charset, ink and paper back. Otherwise it quickly becomes co...

In my Novalight tests, IIRC both had their advantages but Oricutron was better on the speed - Euphoric used to slow down a bit. About your 4800Hz file, beware that files under 11kHz are not perfectly re-read by most players and create loading errors - it's a well-known problem by people that have be...

And yes i remember now, many MFM DSK files images are more or less broken (...) What was the purpose of this file format ? From the design/specifications it should support some copy protections but since many images appears to be broken i am not sure anymore. It appeard to allow the disk transfer o...

There's also the hardware tape on Euphoric - but the emulator is plain DOS and may be a bit painful to install these days.

I recall testing Novalight WAV files with both Euphoric and Oricutron.

See Space1999.zip containing original DSK, converted HFE image that does work via the Cumana Reborn on my Oric Atmos and finally the image converted back from HFE to DSK using the export to Oric DSK. Which does not work in Oricutron. I spotted a small "bug" in the header: the geometry is missing. I...

That's where I'm lost.
I think HXC with usb supports Oric DSK, but not HXC with SD cards - at least this was unclear a while ago, be careful.

Same as Ibisum, this is way beyond what's left of my mathematics level.
But there are two things that this gives me hope for:
1- drinking Champagne
2- seeing Mercenary on Oric some day

I don't know for the 1.22 ROM... But if this can help, on ROM 1.1b, I found this back: replace, in #F934, #1E by #1C; and in #F9CA, #1A by #18
(this was from an email with Fabrice F. and Nightbird, and I tried it myself successfully at the time)

Well to be honest I don't see any problem with the loading routines code on Oric, except as Chema noticed the mess with error detection in ROM 1.1, leading to "errors found", or lack of "errors found" according to different 1.1 versions. But this is just the control. The loading routine itself is ra...

Remember Progress? ;) https://forum.defence-force.org/viewtopic.php?p=16736#p16736 - Progress bar - Live loading parity error detection Only on Atmos though... Funnily, see the very last post of the thread: Dom asked for this to be in the Rom, too ;) The other problem I see with re-writing ROM routi...

It all depends on what you mean by "not great"
If you mean improvements like block loading with checksum or things alike, true the loading code is rather "basic".

But about loading reliability, as far as I've understood it's rather a hardware or tape recording quality problem!

What was done on Mercenary III for Atari ST and Amiga was storing the text on 6 bits. Hence 3 letters on 2 bytes, allowing 64 differents signs (26 letters, 10 numbers, and space and "!*,? etc.) Along with a dictionnary of 5 or 6 words, which I guess used some of the unused values among the 64 possib...

Stupid question on your 1st attepmpts: do you 1st plug the power supply to you wall plug, and then plug it to the Oric ?
By doing it the other way (plug Oric 1st, then power supply) my Orics remain in this garbage boot screen.

Thanks for sharing!
Will take a look some time

A few more, from memory: - Harrier Attarck alos requires a second button (fire on planes or drop bombs). With the PASE interface and the Joystick Adapter program, it required a second joystick, just to fire ;) - Xenon-1 could also bee considered requiring a 2nd button to call the refuel level. I can...
