I diden't pay much attention to what you were doing Corey, now that I know it's a PMD MMO, I want to help. Here's all the stuff I worked on from my last PMD MMO. I can truthfully say that is is mostly my work or someone who worked to help me's work.
Music:
*Got some off of youtube, others from the ROMs themselves
GFX:
*I poured my heart into getting good PMD dungeon tiles, I hop you will use them well. (I also wish that the idiots at TSR would put my tilesheets on the website)
That is all I have to offer. I was working on my own PMD MMO again, but I tried to hard to do source edits and failed. I also had a GUI that customly fit the source edits.
