You'll have to patch a few lines. BTW, there's really something strange. I
had to exchange stat() against lseek() because stat() sets statbuf.st_size
to 0 here. I cannot understand that at all. The patch is at the end of
this post. Move to generator-0.34/main and run "patch < patchfile".

Alad*in without sound? Are you crazy?? ;-) Most Genesis games have really
cool sound. I wouldn't want to miss it.
