well, i have the gbc emulator, and the roms ive tried so far have worked perfectly, except pokemon puzzle challenge (which was the game i really wanted). the music is really slow, and there are weird lines in some parts, and the blocks disappear really slowly. has anyone else had this problem or can tell me what to do? ive tried roms from 2 sources, and both were like this.

 

yea, i did. and i have it on my firecard. but i just like pokemon puzzle better.
