MAME seems to be extremely unintuitive to use and extremely poorly documented. But it supports a ton of machines, some of which I haven't found other emulators for, so I've been persevering with it anyway.
One thing I haven't been able to figure out how to do so far is how to save to tape in any emulator file format other than WAV.
Even the fact that it's saving WAV took me a while to figure out because it can load the typical emulator tape formats that most emulators use.
For the Sinclair Spectrum and Timex 2068 I would normally use the
.tzx formats and for TRS-80 model I would use the
It loads all these formats perfectly fine. But when I use the same file extension to save, it seems to write not in that specified format, but only in WAV. I couldn't get them to load back in after saving them. Only when I used the Unix
file command on the resulting files did I see they were all in WAV format.
Am I missing something where I should be able to specify what tape file format to use for saving or does it save only WAV by design?
