I did some experiments with bank switching, and it was working here, but I used OUT and POKE from ZX BASIC, not in Assembler yet.
As for Interrupts, I usualy preserve all registers that are used by my interrupt called routine. Switching bank at least destroys the BC register pair, and I'm sure DE is used too somewhere.

Thank you very much for the Nanako version.
I wonder why CEGZ favorited these custom loaders, as they are not suitable for DivIDE or Discs. Baron Ashler even used Alcatraz protection system. My opinion is: if there is a custom loader, then a standard loader must be provided too.
Hey, you used HiSoft Basic? I used it too for all my pre-2008 games until I moved to ZXBC. Excellent work!
