NTSC2PAL

This little routine will run a NTSC system at PAL speed. It does this by
bypassing the ROM's Display-3 routine, which then allows us to change the
margin value from 31 to 55.

Re: Convert a .jpg or .png whatever to a BW ZX image?

It would be nice if there was an option to Save as scr format on the digitize window. Would make it possible to LOAD and SAVE several images without having to leave the window to SAVE the LOADed image.

Just a suggestion, not a big deal.

There are three versions, depending on your hardware. 2001-Z Standard version, ZX81+16K RAM pack, tested on...
