That works. Thanks a bunch.http://www.mediafire.com/?drmznb2fiz5 Try this program, use NSE to open the rom and then go to sprite, then file, export, Nameless Sprite Library. Then Open NSL and import the Sprite Library you just exported, then import your new sprites into the existing one, save it then import the modified file to the sprite you want to replace and it should work perfectly.
If you cant get it to work upload the files and send me a PM with a link and I will fix it for you if you want.
