[RM2K3] HOW TO USE AND LOOP OGG AUDIO FILES?

Well, after a few hours looking for tutorials, information and other kind of help, I'm almost lost all hope to find how to use this patches, specially for the looping audio functions (I consider it essential for every game).

So, I need a lot of help here. I have the official English version of RPG Maker 2k3 through Steam (that means that I cannot use the Harmony patchers with the program), and I'm trying to patch a project in order to use the audio loop and OGG files (I have some problems with WAV and MP3, and also I don't want to use them).

My questions here:
-What are the patches used for this?
-In case it's possible, how to use OGG in my project?
-And the final question: how to loop them?

And please, I need the details you can give me about this.
Thanks in advance!

As far as i know you cannot use ogg files on the new rpg2k3 (steam version) since it isn't compatible with things like dynRPG, but i might be wrong.

You cannot patch the program, but your projects can be patched without troubles, as I know. I even tried the patches in a empty project and you can use OGG audio instead of the default WAV and MP3. But what I need it's a tutorial or instructions to make my OGG files fully working, with loops included.

Oh that. You need to download the latest version of Audacity. If you give me a few minutes i'll give you some step by step gifs on how to loop it.

Thanks, I already have Audacity installed and I know how to do loops inside the comment tags (with LOOPSTART and LOOPLENTH). The last time I tried to use them in my 2k3 project I used them but the loop didn't work. The music repeats from the beggining.

That's the reason I need a full tutorial for use the patches and the OGG files.
