WORDS FROM THE AUTHOR

I started this patch on a whim after seeing the game mentioned in the video
"Lies of the Robots" from Modern Vintage Gamer (greetings to Dimitris!).
It's a shameless rip off of the NES Mario Bros but it's really fun to play,
and nicely presented.

The game works well for the most part but there were a couple of bugs that
needed addressing. A misread of a data value resulted in the game accessing
chip memory higher than 512k when it shouldn't. There is also a bug where
sound effects either go missing, or noise will play instead.

It turns out that the game carefully sets up the audio DMA channel it wants
to play, but then instead of switching on that one channel, it accidentally
switches on all of them, due to the register used for tracking the DMA
channel being corrupted by a loop. Easily solved, and quite understandable
how it got missed.

Added the usual extras like trainers and saved highscores.

Enjoy! :-)

Greetings and thanks to DanyPPC at EAB for testing, and to the WHDLoad team.
