Direct using of ROM routines is not a viable option but what would make more sense could be a "reimplementation based on the concepts" found in the best (definition of "best" to be defined :-) out of the available ROM (or external) implementations. Of course some targets might not be able to use it due to memory constraints, but this is secondary. Many would benefit from it. -- SD! ---------------------------------------------------------------------- To unsubscribe from the list send mail to majordomo@musoftware.de with the string "unsubscribe cc65" in the body(!) of the mail.Received on Wed Apr 28 18:03:26 2010
