This is quite an evil size optimisation used in the boot intro I planned to release at FAP. For now I have to admit defeat though as I didn't manage to cut it down to 1024 bytes despite lots of such tricks, the code is nearly unreadable! :D Let's see if I can make it for FAP 2014. :) For the 2013 edition I have a plan C intro ready. :)

Haha, this one is slower

add eax , [edi + 4]
add eax , [edi + 1280]
add eax , [edi - 1280]

than this

mov edx , [edi + 4]
add edx , [edi - 1280]
add edx , [edi + 1280]
lea eax , [edx + eax]

Ok,. some time ago I used ARJ to compress a big file to many volumes succesfully.

I try again and I fail every time. The file is a ZIP of 3Megs, I want to compress to volume of around 700kb with arj a -v700000 dos.zip dos.arj
It make an arj of volume 700k and stops there. All the time. With different tests, maybe it should not be dos.arj maybe *.*, maybe this maybe htat
I did this all the time.

Then I do the same on the folder DOS. And it fucking works!!!
Wtf? If I point to a single file it stops producing many volumes? But not in multiple files? What is that madness???

Anyway,. problem is I have a 286 with 720k but dos6.22 is only 1.44 images on the internet.
