Denial

I know that sjload work with jiffydos modified drive, so I suppose that with a real drive (as 1541) I need to find the sjload-NTSC version for NTSC systems and a sjload-PAL version for PAL system, is it right? and where can I find them?

I know that easyload work with not-modified (real) drive, but do it work with both NTSC/PAL systems?

Thanks!
