Euphoric restoration problem

Hi everyone,

My name is Patrice Torguet. I am from Toulouse, France.

I have an Oric Atmos but unfortunately it has a graphics problem (the sound works well though).

So I use Euphoric and other Oric emulators.

Recently I have found a bug with the restoration feature.

When I use "euphoric -r" to read a memory dump, euphoric loads the backup but then the keyboard isn't working anymore. The F1 and other function keys work though.

I have tried this on:
* Windows XP using the last version of Euphoric (1016);
* Mac OS X 10.9 using 3 versions of DosBox (0.70, 0.74 and 0.74-1 [looks like it is a Mac OS X specific version] - I thought it was related to it at the beginning) and two versions of Euphoric (1016 and 1015);
* Win7 x64 using DosBox 0.74 and Euphoric 1016.

I posted the problem on oric.org forums, Maximus checked it on his own Euphoric and had the same problem.
I have sent an e-mail to Fabrice (I know him from a very long time ago) to report the problem but I think it would be good if several people checked this problem.

I have a Dump available here if people want to check it:

When the keyboard is not working, does the "PASTE" feature work ?

I didn't even know there was such a feature in Euphoric.

How do you use it ?

As far as I know only oricutron's last version has paste functionality.

Oups sorry, I misread the first post and tought you used Oricutron and not Eurphoric, please forget what I said :) (BTW, you should move to oricutron, euphoric is now a really old thing)

Well I think both emulators have their strengths and weaknesses.

Euphoric is most of the time faster.
Specifically when loading tapes.
Oricutron is so slow for this.
I plan to look at the code and try to make it faster.

And Euphoric is not old, the last version is dated from July of last year. Not that old in my opinion.

Oh and of course it is coded by Fabrice Franc├Ęs who is the living god of Oric ;)
I know, I met him and worked at his workplace in Toulouse.

I found an even older version of Euphoric (1007) and restoration works okay in this build.

So something happened to the feature between 1007 and 1015.

I don't have build between those to find out exactly which one broke it.

Had a few more versions: 1009 still restarts fine, 1013 is keyboard-broken.

mmm Fabrice added a more realistic emulation of the keyboard matrix behavior in the recent versions; something we found when making 1337 compatible with the Telestrat (yes he found something related to the keyboard and also a bug in the Telestrat disc hardware).

Maybe the changes had a side effect when restoring dumps? It is hard to say...
