Help H5 pt5 system protocol 273

[BioKryptY]

Guys I'm racking my brains with this, I need a system h5 that works 100% on the following protocol: 273, but all I find are 268.

The ones that are 273, like the rpg club, etc and others that I have, when I open the inventory, or other things from this photo crash below, what can it be? I'm trying to find a functional system 273 to be able to edit the interface, because I've tried with protocol 268 and it didn't work. What am I doing wrong?
