- OK. Got me :) But well... it should not be THAT HARD to use one c2p more... as

- Hmmm... my problem about this stuff mainly is, i only have those c2p of
- Aminet... the GD stuff does not fit to my library system (scrambled c2p does
- not fit...), and of others, i simply have to use what is available, as i never
- before did a c2p code... and others probably can do this better... if someone
- provides me the needed c2p... okay... else i will use what is available and
- try to do the best out of it... But your statement has a point, and i would
- like to do it this way... :)
