How come it took so long ? Just make a file containg the code and then use
DASMZ80.

This sounds very unlikely, I know that Crash_Man soend a long time
optimizing the code.

One matrix covers the whole system RAM, the first time you store a number
to it stores a key in the buffer, the next time it changes the input
handler.

Ash 3.1 will run Crash programs, and it includes all the extra Crash
routines and some new ones. The last time I tested Ash 3.1 all Crash
programs except for Crash for CrASH worked fine (however i made a small
mistake in the version I send to the beta testers). The routines included
in Crash are (c) by the authors of Crash, you have no right to take their
routines and use them in any programs. None of the routines are hard to
write, just sit down and write your own.

Have a look at what happend with the TI85 when every one started to write
their own shell. Now every one writes shells, and not games. If you
release the code for CrASh my guess is that the same thing will happen to
the TI82.

I know for a fact that the authors of Crash did not want to release the
source for Crash, and I am sure that they would not like any one to
release it. They wrote CrASh and unless you get their permission to
release the source for it you have no right to do it. So just keep the
source to your self.
