Help to change name of games

[hhisc29926]

Thank you for your prompt answer. I have a better idea about what I have to do, but that is still not enough, as I do not understand how to do that. I have researched for more hours now, and have installed "PSPISORenamer" and "PS3Tools", but have no idea about how to use them (or if any of those programs is what I need), they have no instructions, and I have not found anything online, other than doing it for Play Station 3 and/or 4, it seems that noone is interested in Play Station Portable. Could someone be so kind and help me with changing the names of games, as it is so frustrating to see those stupid names, and it is also hard to find the right game because many have wrong or ununderstandable names?.
