Apologies if this is in the wrong area
What changes would I need to make to convert a spectrum game to the 81 or 80?
any ideas?

In Heck, there are two options for perpetual torment:
Eat the Puckerberry and suffer for eternity:
drink nothing but a cocktail of The Last Dab and Mexican Cake blended and served with
habanero slices

Never tried it, but feels like it would just be easier to write from scratch.

Speccy: 48k, +, +2, +3, TS2068, "Bare Metal" Pi, Next KS2, IF1/Microdrives/Vdrive/Light Gun/VGA-Joy

Easiest way would be to supply a ZX81 with the sponzy ROM. This is a spectrum ROM modified to run on a ZX81.
Pure basic still is a problem because spectrum has multiple commands on each line which have to be single commands per line.
Graphics is far enhanced compared to the ZX81.
So it's really easier to rewrite from scratch.

In theory, there is no difference between theory and practice. But, in practice, there is.

I converted my Shogun game into a ZX81 game.
I had to alter the source on several points
1) skip use of IX and A'
2) make new display on screen
3) alter key reading
and your game needs to fit 16K
