Colecovision library and tools update

[PkK]

Dear ColecoVision developers,

 

a little later than usual (I try to sync it with sdcc releases) here

comes the update of my ColecoVision library and tools. There's less

changes than in previous releases, which may be due to the tools getting

more mature or due to only about half a year passing since the previous

update.

 

The updated libcv can be found at

http://colecovision....ent/libcv.shtml

 

libcv changes since 0.20:

 

0.21:

Suggested compiler: sdcc 3.2.0 or newer

libcv: Initialize RAM to zero in crt0 to ensure that global and static

variables are initialized to zero as required by the C standard.

libcv: Do not explicitly initialize cv_vint_handler and cv_vdpreg[0] to

zero (since they're implicitly initialized anyway).

demos: Make sprites transparent in compression demo.

 

The updated compression tools can be found at

http://colecovision....mpression.shtml

 

compression tools changes since 0.1:

 

0.2:

* Fixed empty path stack error message in huffman_encoder.

* Code cleanup in huffman_analyzer.

* Fixed bug that could result in wrong character frequency counts in

huffman_analyzer.
