Tips for editing bgms loop

[Slayer.]

I've been wanting to do this for a while, and actually I've edited some musics with Audacity. Although apparently it looks ok, I'm not sure if the result was 100% good. Considering that I have quite a number of tracks that I want to edit, would you guys who are experienced in the matter have any tips or do you know of a program that would make the process easier? Trial and error to find the loop point in Audacity doesn't seem very reliable to me.

When you say you do it with Audacity, you mean like this?

Because if so, well, it doesn't get any better than this. At least this is what I do, import the music in Audacity, change the time selection to samples, find the loop points, copy them to mugen.

Not really. I edited the mp3 files themselves to make it better (?), with the intention of making it compatible with WinMUGEN (not that I use such version). And also I found this tutorial here:

Although the program detects loop points automatically, it doesn't cut but extends the music for other purposes. So I thought there might be some way to find the points and cut automatically. As you said, trial and error is not ideal so my question is if there is any tool for this or I will have to convert a few dozen tracks the old-fashioned way.


Edit: Since no one else has responded, for now I believe there is no automatic solution. In any case, with the answer given, it was quite easy to resolve the situation for most songs as you can literally see where it repeats itself as a graphic tile. Thank you.
