Pocket Zone Item replacer?

[Flammable]

Hey guys,
I was playing the game Pocket Zone but my profile got blocked from the online features of the game. I made a new profile but there was one special item not obtainable anymore and I had it on my old save. Since all values (as far as I know and tested - currency, time, points, etc.) can be modified, there should be no problem to replace/modify items as well, right? I just have no idea how to do it. I want to replace one artefact with another one. There was something similar in the Last Day On Earth game in the past as I remember. If you can help me I'll appreciate your effort. Maybe if it's allowed, I can tip as well. If somehow the value/address for the said item can be found and another one can be replaced with it it should work or? I'm just throwing guesses...
