Konami Synthesizer .cas files
-----------------------------

The original Synthesizer cartridge came with a tape, which contains samples. 
Saku Taipale <staipale@miranda.dc.turkuamk.fi> has the original game, and sent 
.wav recordings to me, Sean Young. I've converted them to .cas files. The .wav 
recordings were over 80MB, the .cas are just 87KB. :-)

Many thanks go out to Saku Taipale. 

Just a little (technical) background: Synthesizer, the cartridge, has 32kB
ROM and a DAC (unbuffered D/A converter, unsigned). It can be accessed
through memory mapped I/O address 4000h.

As far as I know, the only emulator that emulates Synthesizer correctly is
MESS:

Sorry for the promotional blurb.

These .cas files are actually just samples. It's 8 bit, unsigned and about
11025Hz (remember that these samples are played at different sample-rates,
so they were designed to work with different sample-rates.

You can actually just play the .cas files (provided you can convert them).
So for example under Linux, this will make you hear the samples:

play -t .raw -u -b -c 1 -r 11025 Synthesizer-Dog.cas 

You can do that with all the files.
