The story so far...
-------------------

Finally, after 3 years of (on and off) hacking, Digger is back! This game, for
those who don't know it, was one of the best games available for the XT - the
CGA graphics were beautifully drawn and animated, and the sound effects and
music were state of the art.

It wouldn't run on modern PCs, of course. The CGA graphics directly accessed
hardware registers that the VGA didn't have (and wouldn't have looked so hot on
today's high resolution monitors anyway), the background music and sound
effects just didn't sound right and the whole thing just ran far too fast.
Also, you probably didn't want the game to access the disk directly and save
your high scores in an arbitrary place (probably overwriting some other file)
or to reset your computer just to exit the game.

I was extremely disappointed to discover all these things when we replaced the
family PC1512 with a brand new multimedia 486, so I set about re-writing it. It
was a big job - all the code had to be disassembled, the necessary routines
re-written and the whole thing put back together again. I finally finished the
project in Easter 1998, having decided not only to fix all the compatibility
problems but also to convert all the graphics to VGA standard, redrawing them.

Since then, I have almost completely rewritten Digger in C to make it easier to
add new features and move it to other platforms. This is the result!
