Pre-Requisites:
minicommander,
classeditor,
Calc4M, image file in .png xtension
IMPORTANT THINGS YOU MUST WRITE ON A SHEET OF PAPER:
1.) image size (ex. 5000 bytes), this is the image that you want to be your new splash screen(e.g. .png .jpg etc)...
How to acquire?
Using classeditor, view your image file and press left soft key and look for its size: 5000 or highlight all the contents of image and @bottom you could see its size
2.) current splash screen size (eg. 722bytes) where can you find this? Using minicommander, extract the "v" file of your OM4.2 zip, then read it using classeditor, then press 9 and type 'PNG' on Text textbox then press "Option" > "OK", press direction key, now you're on the first PNG, just press# to proceed to the second PNG. Now highlight starting from the box before PNG until to the last part of the image code,PNG......IEND B, and look for the size at bottom, usually the opera default splash screen size is 722bytes.
3.) 14 hex values (ex. 2CDC, 2CF8, 2DBF etc.) where can u find these codes?
Read the v file by class editor, then press '0', now you can see 2 windows (leftwindow:hexvalues| rightwindow:symbols) press '7' , clear whatever u see nd type '27' nd press 'OK', Press '4' nd then '6'... the default is 2CDC, the second is just located next to it after 4zeros 00001st00002nd00003rd...000014th, it should look like this, 00002CDC00002CF800002DBF...0000384B, now, you have the 14 codes.
AFTER YOU COMPLETE THOSE DATA GET YOUR CALCULATOR OR GOTO YOUR CALCULATOR SOFTWARE AND PERFORM THESE COMPUTATIONS
Lets use the example data
-imagesize=5000
-splashscreensize=722
-hexvalues=2CDC,2CF8 etc.
Subtract 722 from 5000, "5000-722=4278"
then get the hex value of 4278 using your calc4M. Type"4278" then press down key twice (2x) nd hold d hash (#) key.. You can see its hex value which is"10B6". Now add that answer to your 14 hexvalues each, 10B6+2CDC=3D92 and so on, now"3D92"is your new hex value that will replace 2CDC, the same procedure for other hex values.
After you compute all new hex values, using classeditor edit your v file, replace the 14 old hex values by your new computed hex values, and also replace the old splash screen image(722bytes) by your image(5000bytes) then save it and return it to your zip file, rename zip to jar and witness your new splash screen.
Note! You can use your v file on other OM.zip. The old hex values are not always 2CDC and so on, the same as to old splashscreen image size 722bytes, ex. 2F7F, 65000bytes&others, just follow the process to avoid errors..
