Software on vinyl for Sharp MZ80K (i mean)

Post by Dandu »

Hi

I have a question for you, guys

I'm a french blogger and i like to decode and launch software for old computer stored on vinyl records (i have a large list) : https://www.journaldulapin.com/2021/08/ ... dersnatch/

And my last vinyl is from sudden sway (https://www.discogs.com/fr/Sudden-Sway- ... ter/370182) , with (i mean) two software for the Sharp MZ80K. On another LP (https://www.discogs.com/fr/Sudden-Sway- ... se/1869149) there is a program for the Sharp too (but i have not this disc)

By the way, i have recorded the audio, but the Sharp MZ80K is a little complicated for me, and i'm not totally certain that the software is for this particular computer.

Can you help me ? I will try to confirm that the code is for the Sharp MZ80K, and if possible, i will try to launch it. I have tried with an emulator, i launch the computer, i use the command LOAD and i press play with the WAV file but nothing happen. Is this the right way ?

I join a sample file.

Thank you

Pierre

The wav file is too short and has only zero level.

Ah désolé, je me suis trompé de fenêtre (j'ai plusieurs fenêtres Audacity ouvertes). J'examine...

je n'entend pas le header caractéristique (un espèce de "bouingue") et ça me semble un peu répétitif comme motif.

To have an idea how the header starts (it always sounds similar for any MZ-80 K program in a wav file):

I cut the big part of the data so it won't be loadable but at least you hear the wav file.

Thank you (merci)

Je vais essayer avec le disque complet, pour vérifier s'il y a bien le header. Il faut que je le trouve pas trop cher, maintenant.

Le morceau que tu as choisi n'est ni un bloc de donnée régulier ni une entête d'un fichier pour MZ-80 K. De plus il est extrêmement court.

I got Sudden Sway from somebody a long time ago but couldn't get it to work either. Here's my one.

This is what I get with my SpaceRally.wav:

Code: Select all

LONG:1;tick0=10.7;tick=7
LONG:1;tick0=10.1;tick=7
LONG:1;tick0=10.1;tick=7
LONG:1;tick0=10.9;tick=6
LONG:1;tick0=10.4;tick=7
LONG:1;tick0=10.2;tick=6
LONG:1;tick0=10.5;tick=6
LONG:1;tick0=10.3;tick=6
LONG:1;tick0=10.1;tick=6
LONG:1;tick0=10.7;tick=7
LONG:1;tick0=10.3;tick=7
LONG:40;tick0=33.0;tick=22 <----- Good it founds out a LONG40
SHORT40:40 <--------------------- then a SHORT40: we have a header here!
10F0 01 53 50 41 43 45 20 52    12.083s - 532870
...
On the other hand, "sudden_sway.wav" which sounds very much like a MZ80 K program is un-extractible:

Code: Select all

LONG:20;tick0=34.1;tick=21 <--- LONG20!?
SHORT20:19 <------------------- then SHORT20!?
And it exits with no further informations.

Looking at sudden_sway waves, they are bad (see circles) so saturating them to ease transformations is almost impossible. it needs to tracks peaks and square them to 1.0 when max and to -1.0 when min.

Hello,
With my WAV translator program -> MZF I found this program for the fie Sudden_Sway.WAV
It's basic mz80 apparently and it looks like a game...
To be checked...
