This is a collection of MS-DOS/FreeDOS-based utilities, which may be useful for others who are interested in retro (legacy) systems. All of these tools are licensed using GNU General Public License v3.0.
If you found any of these utilities useful, please let me know at rink@rink.nu !
- GDB debugging stub: TSR allowing GDB to interface with your DOS-based machine using a serial port

- DOSVGM: DOS-based Video Game Music (VGM) player for VGM/VGZ files. Supports Adlib, Sound Blaster and OPL2LPT/OPL3LPT output devices.
You need to install nasm, mtools and OpenWatcom (I used the September 2023 snapshop of version 2.0).
All utilities have a build.sh in their respective directories. The build.sh in the repository root directory will build all utilities and create utils.img which is a 1.44MB floppy disk image containing all utilities.
