I also had an issue with Twinkle (1983)(Gem Software). The player ship drifted to the left and continued to fire, and you don't seem to have any control over your ship.

Tried loading a WAV file or two now and again, followed @NML32 video, followed @Ron's instructions but still nothing
I followed my video and was able to load and play Muncher.
@EeDee I sent you a PM.

I just discovered this.
For loading I tried "Oh Mummy".
As a Linux used I ran "./lynx2wav -5 Oh\ Mummy\!\!\ \(1983\)\(Gem\ Software\)\(GB\).tap ohmummy.wav"
Volume was 80% (I had success with that on the Otic core) and I use the normal Linux play command with headphones socket connected to audio-in.
TAPE 5 first on all attempts.
Did MLOAD"" and it showed a file name but didn't load.
Did MLOAD"OH MUMMY" and it got to the end and said, "Bad Tape".
Changed volume to 75% and it worked!

No need, it worked. I was just pointing out my process.
Now I just have to figure out how to get a loud and clean enough output to save successfully ;)

Actually I think the problem is with the input on the computer line-in picking up noise from the motherboard (integral audio). I've also tried a USB sound device for input but it's really cheap so I don't think it's good enough.

I have been using my old Sony digital Walkman (decent quality mp3/wav player) and has been more successful than not. My old Lynx was quite volume sensitive I seem to recall.

Is there any chance of this core getting tape image support ?
I did all the tape-loading thing back in the 80s, I don't really want to do it in 2021.

What's the latest with this core? Is it official yet? I'm setting up retronas and trying to figure out the roms folder structure and naming to add the Camputers lynx collection to it.

Dropped 8 months back. Probably could do with a sys update looking at it, hasn't been updated since then.

No problem.
Please let me know with a post here if there are any issues or improvements to anything that was appearing after the initial release.

The folder name is "Lynx48".

Ah, yes, seems he was a proud Cambridge dweller.
"The Lynx’s own origins go back to early 1981 when Richard Greenwood, founder of small Cambridge-based electronics design company GW Design Services (GWDS), decided to establish a second firm to make and sell microcomputers. It was called Camtronic Circuits, though it was later renamed Camputers."

I think it was a play on words. It was built in Cambridge in the UK hence Cam and Puter

Cambrigde Computers, Camputers ! xD

in the 80s Cambridge was the center of the world in computing, at least in Europe. Most and the best micros were born in Cambridge
