Bye Bye RMXP! The graphics can stay though.....

Righto. I have completely given up on RMXP, and am going to revert back to RM2K3. Of course, I'll keep a copy of XP, for educational purposes. What I am gonna do is change ALL the rmxp graphics so they can be used in rm2k3. Of course, this is gonna take a helluva long time. Anyone want to help? Anyone got any tips of how to make this quicker? Anyone who will be wanting some of these graphics when converted to use in their rm2k3 game?
