2 major goodies:
1) a fully working Easter Egg:
In URU:CC, it's all broken. Yes you can ride that Zandoni but after the 1st crash... well it's back to Relto after a crash on the desktop. On Until URU, you can crash and crash and crash, all you want because you just hit the spacebar and the Zandoni is back at the start ready to depart again
And when you are tired you just Relto out and that's it, you're back to normal ready for another journey.
2) the balcony jump:
In URU:ABM, you can have it too but try to run that program... I cannot. In URU:CC, you can also but you need to fiddle something in the code to get rid of the blockade. I prefer keeping my URU:CC intact of those kind of hack.
The City Extensions created by Chacal are also installed there. I also deleted some nasty panic link zones here & there in different ages. In fact, for the Easter Egg, I don't even have to do it, the fences are crossable in Riltagamin. It's a highly customized game that I've got finally
