WORDS FROM THE AUTHOR

Another Dizzy game whose install was long overdue for an update! The version on
SPS was missing support, and there were some missing nice-to-have features like
2nd button jump and trainers I wanted to add.

Supporting both versions was quite time consuming. They're basically the same,
but one has had some tweaks and optimisations compared to the other. While the
broad layout of the code is the same, there are subtle differences everywhere
that meant I couldn't just use a single offset to port the patch from one to
the other - every routine needed me to re-check its position manually!

I've changed over to using real files for the install, as there's a lot of
wasted space on the disks, and I think it's nicer to be able to get at the
files used by the game more easily (e.g. music). It also means you can pack the
files using RNC or any other method WHDLoad supports if you want.

The game has some incredibly slow loading times! I've been able to pick this
up a bit by skipping unnecessary sequences (developer logos, Game Genie), which
can always be re-enabled if you want. The RawDIC imager also unpacks the
compressed game files (mostly music+sound effects), as the decompression in
game is very slow. An advantage to this is you can load the ProTracker music
now if you want - files data53/54/55/85/86/87 are all the tunes. 

The fast/super fast Dizzy speeds are different values to the same trainer, that
was originally a Game Genie code. "Fast" is the original boost, while super is
a value I felt OK as an even faster mode. If you want to play with the speed
you can set CUSTOM4=x to try other values for "super fast". (Default is 20.)
I felt it was simpler for the trainer to keep to a couple of speeds. :-)

While testing the infinite time trainer for the Ice Palace level, I realised
it was possible to cheat to freeze time anyway - when the timer appears, move
a little to the left and it triggers the 'failure' event that stops time, but
if you haven't moved over enough you can still go right into the maze, and get
the crystal anyway! Developer bug, or intentional cheat? You decide!

I had a lot of fun making this patch, especially finding different trainers
I could add to make the game less frustrating. It's not the best Dizzy (and
quite easy really), but it's a fun diversion for a bit. Enjoy!
