Sorry for jumping on this a bit late in the day. Its been hectic. Still getting time to work on the next assembler shell which is nearly done.

For what it is worth when I had tapes that wouldn't convert first time, I had a simple routine that would convert the wavs to bytes. Then another script that shifted these bytes a further 7 times creating a new file each time.

This meant on some tapes, primarily basic, I was able to view the data using a hex editor and see where bits had been dropped/added. A bit laborious but did work. I then patched together all the fragments together.

Note as a first step I would always use audacity to normalize the wav and increase the volume.

I've still got a couple of wavs I couldn't convert so will run them thro bills scripts and give them another go. I've also got a couple of mp3s that I can't convert but are known to work on real hardware. It will be interesting to see if they work on Bills version of Memu.
THIS is what Memotech is doing now.

Hi Dave
I tried to use the appmake tool, but I cant get it to work.
Have you successfully made a new wave from a previous MTX file ?

For programs that already exist as MTX files, I think that there is software already available to do the job.

The AppMake tool that is part of Z88DK should be able to generate a "clean" .WAV file from the digital .MTX file.

Paul will know more about this, but this might save you doing work that might not be required?

regards
Dave

I just converted Toado to wav using the "Toado (1984) (Continental Software).mtx" rom file. I used the following command line (I'm running it through Wine):
$ wine appmake.exe +mtx --dumb --audio -b /home/muldjord/Downloads/roms/Memotech\ MTX\ \(GoodMTX\ v1.02\)/MTXMerge/Toado\ \(1984\)\ \(Continental\ Software\).mtx

It created the wav file with the same filename in the same folder. Just tested it on my Mtx512 and it works brilliantly. I couldn't get the wav from mtxworld to work, so this was a nice surprise.

I just converted all of the mtx files I have to wav using the appmake.exe tool. I haven't tested all of them, but the few I checked sounded fine. Here's a link to all of them:

I got it work too :) Great tool.
But I needed to put the wave file on my phone to play it back to the MTX, my Laptop could not generate a output loud enough. Even I put everything at max volume.

The great think about this tool is it make a very clean wave plus all games will work on the same volume setting and the playback device, if you compress the files it will be much smaller in size than compress a analog recording.

Is there still a issue with Draughts ? - I remember it have some display problems?
