New releases of libcv, libcvu, png2cvs, png2cv and my compression tools

[PkK]

It has been a while, but I decided to release new versions today, so everyone can profit from all teh small improvements that accumulated over time.

 

libcv / libcvu changes:

Suggested compiler: SDCC 3.6.0 or newer
libcv: Basic SMS port
demos: Basic SMS port
libcv: Specify preserved registers for asm-implemented functions.
libcv: Optimize return address handling in cv_vmemset_fast(), cv_vmemset_slow().
libcvu: Specify preserved registers for asm-implemented functions.
libcvu: Replaced some macros by inline functions.
demos: Add machine detection demo.
libcv: Add delay to cv_voutb(), cv_vinb() to always meet graphics chip timings.
libcv: Improve cv_vmemtomemcpy_slow() speed.
libcv: cv_get_r() to get the contents of the Z80 refresh register r.
libcv: Fixes in support for super action controller spinners and roller controller.
demos: Fix cursorsmooth demo for roller controller.

 

png2cvs changes:

 

Updated to automake 1.15.1
Update for libpng 1.6 (vs. old 1.2)
Improved error messages.

 

png2cv changes:

Fixed autotools stuff.
Update for libpng 1.6 (vs. old 1.2).
Fix missing include.
Improved error messages.

 

compression utilitites changes:

 

Fix for machines with CHAR_BIT > 8.
Added --help to display simple usage info for huffman_analyzer and huffman_encoder.
Added -o to specify output filename for huffman_analyzer and huffman_encoder.

 

I guess the highlight is the support for developing games portable across the ColecoVision and the Sega 8-bit systems. It has be come quite easy to write source code that canbe compiled into a game that works on ColecoVision / SG-1000 / Mark III / Master System.

I have been very interested in converting a game to sega master system. I look forward to looking into it
