This is a collection of tools I wrote for Project DoomBox
They compile on FreeDOS using FreeBasic and DJGPP. I was to lazy to create 'real' Makefiles and compilation is done using simple DOS batch-files (make.bat).
This small tool prints the contents of a randomly selected ANSI-file to the console. You have to specify a root-directory to search for a random file and ANSICAT will select and print one file below this directory. Printing is throttled.
In order to use ANSI escape sequences you have to load the FreeDOS ANSI driver. E.g. put the following line into your FDCONFIG.SYS:
DEVICEHIGH=C:\fdos\bin\nansi.sys
I use this with ANSI-Art from https://fuel.wtf/
ANSICAT <directory>
This is the first version of my game selector screen. It was written in FreeBasic, but the created EXE wouldn't run on the mainboard of the DoomBox. On all my other DOS computers it runs fine.
The program reads the file MENU.TXT, parses its entries and displays a list of options together with a BMP picture specific to the currently highlighted option.
By pressing ENTER the selected program can be started, ESC exits the program into the DOS prompt.
This is the second installment of the game selector screen. It was written in C using DJGPP and the GRX library. You have to compile GRX in order to build MENU.EXE.
In addition to the menu and the pictures it supports sound playback via a SoundBlaster compatible sound card. The sound code is taken from shdon.com. Because I'm a lazy bum (and the program was written for a single system) the SoundBlaster is hard-coded to P=220,I=5,D=1.
The sound files are from the FreeDoom Project.
The format of the file is simple (see examples):
- "N=XXX" starts a new entry called "XXX". All following lines will be added to this entry.
- "D=XXX" declares the directory to change to when this entry is selected.
- "E=XXX" declares the program to start when this entry is selected.
- "I=XXX" declares a BMP image to be shown when this entry is highlighted in the game slector.
The data of the selected entry is written to EXE.OUT/DIR.OUT (FreeBasic version) or EFILE.TXT/DFILE.TXT (C version). The batch file DOMENU.BAT takes care of dealing with these files and calling the selected program.
The batch file uses "SET/p" to read the selection from these output files. AFAIK this option is only available in FreeDOS.
