Is MakeTZX Dead?
I downloaded MakeTZX as I am trying to have some nostalgia with a Spectrum (I am not mentioning the C64, yet) but seem to have hit a wall. The version I have, 2.(something or other), led me right down the garden path, right up until I tried a practice program sampled with Audacity. I thought that I was gettig somewhere - to find MakeTZX does not work with a 64bit system (Windows). Am I doing something wrong? Is there a work around? Is there a later version that I have missed, somewhere?
MakeTZX
It's now at https://tzxvault.org/tools.htm (I have updated the MakeTZX page) but I don't think it's been updated since 2.33.
There are more modern tools (https://shredzone.org/docs/tzxtools/) so you might have more luck with those!
Incidentally, I just tried it with the WAV of Defenders of the earth using MakeTZX V2.33W under 64-bit Windows 11 and it encoded fine (maketzx -a dote.wav dote.tzx) and ran in SimCoupé. The WAV was mono 44,100Hz 32-bit float according to Audacity.
