Need help with emulator

[retrofan]

Hello everyone,

I have a question regarding the Ishmair ZX Spectrum emulator:
http://dl.consolecopyworld.com/dl.php?c ... um_1.0!zip

Emulator is good but I dont like that the author edited the main screen message "@1982 Sinclair Reasearch Ltd" and put your name instead (@2001 Ishmair Research Ltd).
The screen now doesnt look authentic and I would like to change that part and go back to the original state, but I dont know how.
I tried with a hex editor to edit 1st_read.bin but I couldnt find this message.
Perhaps the spectrum rom is somehow encrypted so it can not be found or is something else, I do not know.
Would anyone could help me on this?
