Well when I started using RMXP, I discovered that the midi files couldnt be heard in game play or through the music testing feature. So, I looked for a day and just when I was about to give up, I found a post telling me that XMPlayer could be used with soundfonts and then from there you can make midi's into oggs. Because it took time to make all the files and even find the software to do it ( XMPlayer (freeware) site: XMPlayer (Read the help file on how to get the sound fonts and use them to convert to OGG.)) I decided to add a link to the files so you can download them in OGG format and not have to convert them. If you need more converted files, just use XMPlayer to do it. Below is the link, but please note that all I did was covert files made by Enterbrain. I didnt make the actual music itself. (Legal purposes.

OGG formated sound files
Oh, and I made a remix of the Dark Lich's music from Secret of Mana and its in there too.
