SC22PC - Convert MSX Screen 2 bitmap pictures into ColecoVision bitmap pictures

by Daniel Bienvenu aka NewColeco

January 2017

 

 

Description

 

This tool extracts the PATTERN and COLOR tables (6K each) from a MSX .sc2 file and save it into a neat 12K .pc file.

 
 
Technical Infomation
 

MSX .sc2 file is essentially a memory dump of the seven (7) video registers followed by 14K graphics data in video ram, aka VRAM. Technically, that includes also sprites which can be used to patch the picture to avoid color clash effect.

 

ColecoVision .pc file is simply the bitmap screen, composed of 3 charsets, made of two (2) tables: PATTERN and COLOR. No sprites data.

 

Note: It is possible to use .sc2 file into ColecoVision projects, but be sure to consider three (3) things: the video register flag "4K/16K" has no impact on MSX computers but does on ColecoVision game system, the VRAM data is the important part, a good lossless data compression should be applied on VRAM data to save memory space.
