Please do not ever start a thread anywhere with the subject line "Need help". Don't you think it would have been better if you said "Editing names in NBA Jam PSX" in this case?  I hope that helps.

Does the same thing happen even when you make a small change, like changing a single letter?

Are you editing the ISO directly, or are you extracting files, editing them, and then re-inserting them?

By  extracting those files, editing them, and then reinserting from CDMage. I put the overlay.bin in xvi32 or hxd hex editor then i start to edit the name bank. Afterwards then when i put the edited overlay.bin file back in CDmage and start up EpsxE to see the name changes that i made the screen is all greenish and purple upon starting up the game

What about my other question? Does the same thing happen even if you change a single letter somewhere?

It could be that there are checks in place to prevent making such edits easily. I see there are various hacks available; does it make any difference if you try patching the game before making changes?

Yes, I understand that. My point is that if you can make further modifications to an ISO that has been hacked, then that might provide a good indication as to how to proceed to modify an ISO that has not been hacked.

I think you are missing the intention here.

ABCD

A=1, B=2, C=3 D=4

ABCD and a sum total of 10

If I now send AACD and a total of 10 you know something has gone wrong even if it is the same length.

Games, especially by the PS1 era, had more than enough power to do something similar (or indeed far better from a security standpoint -- in the scenario above DDAA = 10 after all and that is no characters the same) to their data contents. It is not that common and you still mostly found it for binaries (which could be what is housing the text) and in the context of cheat making where anti cheat had been a thing for a very long time by this point, and saves of course but that is a different topic.

This is why you were asked to change a character. Preferably by finding the data in question in the raw iso and editing it there -- removing and inserting with a ISO editing tool can also be an issue, which is why the next step after the single character is confirmed as working is usually to explode the iso into its constituent files and rebuild it to see if your iso rebuilding tool is up to the task.
From there we tend to discuss encodings (did the game know what to do with your edit? Not all games support all of an encoding even if it appears normal or is in the font), pointers (did you accidentally make the file larger and mess things up).

The scratchpad is not for hosting message board images. No one can see those uploads but you. May I suggest imgbb?

Yes, you already said:
Afterwards then when i put the edited overlay.bin file back in CDmage and start up EpsxE to see the name changes that i made the screen is all greenish and purple upon starting up the game
I do not understand why you think posting a screenshot of that is going to help at all.

I have already made a suggestion regarding how you may proceed.

Maybe reinserting the files causes the .iso to be corrupt. You need to verify that CDmage is working properly.

What happens if you extract the files from the .iso, then reinsert them (without editing any files)?

If the new .iso does work properly, then we know it's not CDmage.



When modifying these files, you cannot make the overlay.bin any shorter or longer. You can only overwrite names with a name of equal length. This isn't like a word processor, you don't use the backspace key, every name and value has to remain in the exact position it was in when you started. You have to use the overwrite mode of the hex editor not the insert mode.

Yes. Switch between the Insert and Overwrite modes using the Insert key. You can tell which mode is active by looking at the bottom of the window.
