Right i had this problem to. After 100 trials and errors i got it correct. It is very easy and simple. The Mistake i was doing is ... When you need to split the _mission_recomp.gsc file into 10000 longitude each you will have to do the 1st highlighted bit with no trouble. The second one is the annoying one. All you need to do is highlight everything that isnt highlighted So the file is now split the Ctrl + B over 00014f51

i Love You :muck:

I don't know why are you getting blackscreen... i edited normally and it works for me i translated all the patch and it works, you are probably doing something wrong. I tried some BLUS Patches and when i try to convert to BLES blackscreen comes... you have BLUS?

this is because they are doing it wrong you know i had trouble's because i rushed the Tut. if you want success take your time

Corrected image 13, i forgot that image.

I toke my time i didnt rush it or anything but i did add a extra cohost line maybe thats why???

yh maybe make sure that it exactly da same spaces as other Co-H

I don't think so, its a problem of recompressing.

But at the one part "Enter the offset from earlier
Code:

Start offset: D7D2
End offset: FFFF"

I press ctrl+G or e and i put d7d2 in for my offset to or i put the one in that we get different???
