FYM

Fast YM tools

Tools for creating and replaying FYM files on 6502 computers.
The provided player works on Apple II with a Mockingboard (2x AY-3-8910).

FYM is a format based on the YM format by Arnaud Carré (Leonard). It gives a very good final size ratio without using any form of LZ* compression. The ratio is almost what you can get with the MYM format.

For a complete explanation of how the file format works, please read the associated article here:
