AP not giving any Quick Hacks

[LeKill3rFou]

In this case if I want to equip a lower version of a QH because it's quicker to load and spends less ram, how do I do?

Only the highest version of QHs appear in the Cyberdeck.
So the only way to see lower version is to "sell" the higher version (in short keep the version that you want to see in your inventory and sell all the higher ones).
