I am currently working my way through travelling the desert with Taka and I have just about finished. And as someone who is another of Taka's many fans, I've been trying to gather all possible relationship points with him, both because I am under the impression that dialogue changes are present if you have a certain number of relationship points with him and just because I'd like to have them.
I had been following a guide, but under Taka's points specifically, I didn't see that leaving the desert causes you to lose 2 relationship points with him, and I left in order to get the Pokemon required to travel Teknite Ridge. Therefore, I don't meet the requirements for the dialogue that I wanted to see.
I could load an old save and restart the desert, but making my way through it one time was tedious enough and took several hours, and I would rather not do that again if I can help it. So, is there way to manually edit relationship points, so I can continue on normally without missing out on dialogue?
