Topic 1. Embedding the Skin on
v file
1. Open v file and the skin (pic u
want to use
in .png) file in HxD hex editor.
2. Highlight all the contents of
the skin file and
copy it. You may press Ctrl A
then Ctrl C. Take
note of the value in Lenght
indicator. This is the
filesize of skin in hexadecimal.
3. Goto the v file tab and press
Ctrl F. Search for
"png" text string.
4. Highlight the bytes starting
from 89 50 4E 47
0D 0A 1A or the address
00001DA0 x 0E until the
Lenght indicator reaches C7C.
5. Press Ctrl V to embed the skin
image on v file.
Now we're ready to change those
addresses
embedded in the v file. Change
only the
addresses enclosed with the blue
boxes.
These addresses are for
unmodded v file and
often times changes if
modifications were already
done on the v file.
6. Open the scientific calculator
and put it in hex
mode. If the filesize of the skin in
hex is greater
than C7C then subtract C7C from
the filesize of
the skin. If the filesize of the skin
is less than C7C
then subtract the filesize of the
skin from C7C.
Take note of the the answer.
Add the answer in procedure 6 to
the address
enclosed in a box in procedure 5.
Change
them accordingly to the result of
adding or
subtracting those embedded
addresses
7. Save v file and exit HxD hex
editor.

WinRAR and drag the
v file from the desktop to
operamini...jar.
9. Click Ok and close WinRAR.
10. Finally, install your modified

Topic 2. Changing the Welcome
Page

address. For this
guide I will be using the address
"http://
www.mozilla.com/en-US/firefox/
firefox.html" as
my welcome page.
2. Open v file with HxD editor.
Click the Edit menu
then click on Replace. At the
Search for box, type-
in "http://www.operamini.com/
firsttime/4.2/"
and at the Replace with box,
type-in the URL of
your welcome screen. Click OK.
3. Highlight all the text that are
red color and
takenote of the Lenght value. In
the screenshot I
got a 31 hex.
4. Change the hex value of the
character just
before "http" to the of length in
procedure 3.
5. Now where done with editing
the URL of the
welcome screen. The next thing
to do is to
change the embedded addresses
on the v file. If
the length value obtained in
procedure 3 is equal
to 27 hex, then proceed to the
next procedure. If
the length value obtained in
procedure 3 is greater
than 27 hex, then subtract 27 hex
from the length
and add the answer to each of
the boxed
addresses. If the length value
obtained in
procedure 3 is less than 27 hex,
then subtract it
from 27 hex and subtract the
answer to each of
the boxed addresses.
6. Save v file and exit HxD.
