LIST.TXT

List of entries, one per line, with these columns:

• absolute path with drive letter
• executable filename
• setup program filename (if exists)
• number of cycles
• program title

Lines that starts with # character will be recognized as comments.

Each column must be separated by one or more white-space characters (spaces or tabs).

Executable filename is the executable or batch file to be used to launch the program. Extension is mandatory.

Setup filename is the executable or batch file to be used to setup the program. When setup program not exists a - character must be specified. Extension is mandatory.

The cycles will be used inside DOSBox to automatically set correct emulation speed. If zero is specified 'auto' emulation speed will be set.

The program title will be read until end-of-line character or end-of-file, so it can contains any character.

Thumbnails generation

rloader thumbnails must be standard 4 bits-per-pixel uncompressed Windows bitmap. Only first 14 colors can be used, 2 colors are reserved by the user interface of this program. Width of the image must be 320 pixels.

You can use any command line tool that supports image manipulation. For example using ImageMagick, which is a free and open source tool, you can write:

magick.exe input.png -resize 320 -dither Ordered -depth 4 -colors 14 -type palette bmp3:output.bmp

where:

-resize 320 rescales the image to 320 pixels -dither Ordered applies ordered dithering (optional) -depth 4 specifies 4 bits per pixel (16 colors) -colors 14 remaps using only 14 colors -type color ensures conversion to a palettized image bmp3 specifies an uncompressed Windows bitmap You can avoid bilinear filtering caused by downscaling by adding the -filter flag with the values ​​Point or NearestNeighbor.

TITLE subdirectory This directory will contains optional programs titles screen-shots thumbnails.
