Learn how to use RAM banks in ZX Spectrum 128k. Then compile data blocks as different taps and make a loader. I'm using ZXBlockEditor for gluing blocks in one tap. But now I use assembler.

Hi Boriel

How is that going?

I am having issues on the RAM banks. I try to use bank 4 but when I switch it to 4 the program crashes.

Code:
sub FASTCALL setmemorypage4()

ASM

 LD      A,(0x5b5c)      

 AND    0xf8

 OR      4              ; Bank 4

 LD      BC,0x7ffd

 DI

 LD      (0x5b5c),A

 OUT    (C),A

 EI

END ASM

end sub

I have another one for setmemorypage0() which I call after working on page 4 but never gets to that point.
I do think its a mem clash but hard to track down.

thanks
