These files have been moved to:
This directory contains 8bitworkshop tools for bitmap and
music conversion.
Requires ImageMagick (convert) and Python 2.x.
MIDI tools require Mido (pip install mido).
On Ubuntu:
$ sudo apt update
$ sudo apt install python python-pip imagemagick curl
$ sudo pip install mido
To use the tools, go to the appropriate directory and
look at the Makefile for each:
vcs/ Atari 2600/VCS
mw8080/ Midway 8080
scramble/ Galaxian/Scramble
vicdual/ VIC Dual
williams/ Williams

TMSOPT v.0.1 - Eduardo A. Robsy Petrus & Arturo Ragozini 2007
Credits to Rafael Jannone for his Floyd-Steinberg implementation
---------------------------------------------------------------
TGA image converter (24 bpp, uncompressed) to TMS9918 format
---------------------------------------------------------------
Overview
---------------------------------------------------------------
Selects the best solution for each 8x1 pixel block
Optimization uses the following algorithm:
(a) Select one 1x8 block, select a couple of colors, apply
Floyd-Steinberg within the block, compute the squared error,
repeat for all 105 color combinations, keep the best couple
of colors.
(b) Apply Floyd-Steinberg to the current 1x8 block with the best
two colors seleted before and spread the errors to the
adjacent blocks.
(c) repeat (a) and (b) on the next 1x8 block, scan all lines.
(d) Convert the image in pattern and color definitions (CHR & CLR)
To load in MSX basic use something like this:
10 screen 2: color 15,0,0
20 bload"FILE.CHR",s
30 bload"FILE.CLR",s
40 goto 40
---------------------------------------------------------------
Compilation instructions
---------------------------------------------------------------
Tested with GCC/Win32 [mingw]:
GCC TMSopt.c -oTMSopt.exe -O3 -s
It is standard C, so there is a fair chance of being portable!
NOTE
In the current release the name of the C file has become scr2floyd.c
---------------------------------------------------------------
History
---------------------------------------------------------------
Ages ago - algorithm created
16/05/2007 - first C version (RAW format)
17/05/2007 - TGA format included, some optimization included
18/05/2007 - Big optimization (200 times faster), support for
square errors
19/05/2007 - Floyd-Stenberg added, scaling for better rounding
24/05/2007 - Floyd-Stenberg included in the color optimization.
---------------------------------------------------------------

Use at your own risk, all responsability would be declined.
It would be nice if you credit the authors, though.

TMSOPT v.0.1 - Eduardo A. Robsy Petrus & Arturo Ragozini 2007
Credits to Rafael Jannone for his Floyd-Steinberg implementation
---------------------------------------------------------------
TGA image converter (24 bpp, uncompressed) to TMS9918 format
---------------------------------------------------------------
Overview
---------------------------------------------------------------
Selects the best solution for each 8x1 pixel block
Optimization uses the following algorithm:
(a) Select one 1x8 block, select a couple of colors, apply
Floyd-Steinberg within the block, compute the squared error,
repeat for all 105 color combinations, keep the best couple
of colors.
(b) Apply Floyd-Steinberg to the current 1x8 block with the best
two colors seleted before and spread the errors to the
adjacent blocks.
(c) repeat (a) and (b) on the next 1x8 block, scan all lines.
(d) Convert the image in pattern and color definitions (CHR & CLR)
To load in MSX basic use something like this:
10 screen 2: color 15,0,0
20 bload"FILE.CHR",s
30 bload"FILE.CLR",s
40 goto 40
---------------------------------------------------------------
Compilation instructions
---------------------------------------------------------------
Tested with GCC/Win32 [mingw]:
GCC TMSopt.c -oTMSopt.exe -O3 -s
It is standard C, so there is a fair chance of being portable!
NOTE
In the current release the name of the C file has become scr2floyd.c
---------------------------------------------------------------
History
---------------------------------------------------------------
Ages ago - algorithm created
16/05/2007 - first C version (RAW format)
17/05/2007 - TGA format included, some optimization included
18/05/2007 - Big optimization (200 times faster), support for
square errors
19/05/2007 - Floyd-Stenberg added, scaling for better rounding
24/05/2007 - Floyd-Stenberg included in the color optimization.
---------------------------------------------------------------

Do whatever you want to do with this code/program.
Use at your own risk, all responsability would be declined.
It would be nice if you credit the authors, though.
