Hi All,
I've created a GPT to help me wade through old z80 code. It's got the firmware guide and a few other bits to reference. It's pretty useful!
I've made it available here, you do need an openAI subscription.

Can you post some examples in here? Although I have great success in making chatGPT code in high level languages I haven't been able to make it do much useful in z80 at all, it almost always produces rubbish or dumb code, invalid instructions etc.
