Couple of nice games attached from one of the tapes, looks like a french collection 'Jeux 16K'. Well I can work out the Saturn Lander, but ZXSpace I'm not sure what I'm doing :)

Thanks Fruitcake - the label on the tape says GMSave. My Dad is still around so I will ask him if he remembers about the techniques he used to save stuff.
Thanks. Any info on who made GMSave would be very useful to know, e.g. was it a purchased program or typed in from a magazine.

I think from what my Dad says at the beginning of the recording: "ZXDB with fastbaud 11" might be just my ears and imagination.
Program 1: ZXDB is likely to be the disassembler from Bug-Byte:

Program 2: From the analysis XavSnap has done this is Breakout from CDS:

Although it would be possible to recover the programs from the wav file with some effort, there is little point for programs that are readily available elsewhere.

Yes, it's the same code.

Hi Xavier,

I have been trying to get a better capture of the tape 'Jeux 16k', which seems to be a collection of software that my Dad traded with a 'pen pal' from France. Some of these are pirated copies of mainstream releases but some I kind find any info about or copies online. Unfortunately there are audio drop-outs recorded into the tape, particularly on Side B, and also my expertise is minimal. I have been trying to improve audio capture (I welcome any suggestions for improvement), also I am using 'ZX81 Tape Converter' for software (I'm sorry I haven't got my head round ZXSpecTape yet!). But I upload copies here of what I have, in case they are of use in answering your questions.

Escadrille - I was not able to capture. Pac-man - I am not sure if my Dad might have recorded this on to the end of the tape because it looks different to the over programmes in waveform.

which is just the .p files
A copy of the files with .wav files is here (183MB): https://drive.google.com/file/d/1BTJnbj ... sp=sharing

Very interested if you're able to recover anything. Regards, Will

Hi Fruitcake, I asked my father about this, and he remembers using it but he's not sure yet where he might have got it from - he has suggested he might have got it from Toni Baker's book on Machine Code but he'd not sure. I'm going to send him a link to this thread so he might have some more info. On top of that earlier cassette I have come across a different one where the label suggests that it contains compiler for MC or GMSave. Link is below but there's a lot of distortion recorded into the tape - I don't know if you'd get anything useful from it.

Thanks for your interest in this, Will
