Hi Everybody ,

This is my very first thread at this great forum . I would like to thank you all for this great job and I appreciate the help .

I have an Operating System for a specific Electronic musical instrument ( Keyboard ) . This O.S. consists of 32 Binary files ( total of 1.0 MB size ) . What I'am looking for is to modify the version name at the start-up logo . whereas , the keyboard's screen showing the brand name logo and the version text line . I have found that the Text line I'am willing to edit is located in one Binary file and I could see where it is and I tried to open that file with 010 Editor , Hex Workshop , and many other advanced Binary Editors and I was able to change the expression and save the file as it is . But I'am getting an Error message when trying to upload the O.S. into the keyboard ( CheckSum Error ) . Anyone Could help with this ??? Your help would be most appreciated !

Thanks .......................
