Hot Shots Tennis: Get a Grip - UCUS98701

Looking for some cheats for this game. The only ones that I can find are for store points which doesn't work for me.

There seems to have been some more codes that surfaced for this game a long time ago which refer to this link https://forums.ppsspp.org/showthread.php?tid=10713&highlight=Hot+Shots+Tennis and https://forums.ppsspp.org/showthread.php?tid=23149&highlight=Hot+Shots+Tennis but the links are either dead or send you to the wrong place. I have posted in the ppsspp forums but also like to post here on reddit with the success I have found with reddit in the past.

I was wondering if anyone had a more updated code list for this game that would not mind sharing. I am terrible at trying to make my own codes and am looking for a code that levels up loyalty/xp.

Thanks in advance and hope to hear replies in the future.
