piano to play imple melodies using PC Speaker |
space space arcade game |
x16 PRos includes a small set of built-in programs. You can add your own program to the system image and then run it using the load command, specifying the disk sector number where you wrote the program as an argument.
Here's how you can add a program:
dd if=YourProgram.bin of=disk_img/x16pros.img bs=512 seek=DiskSector conv=notruncYou can read more about the software development process for x16-PRos on the project website: x16-PRos web site
First, clone the reposytory:
git clone https://github.com/PRoX2011/x16-PRos.gitTo compile the project you will only need NASM. Example comand for Ubuntu:
sudo apt install nasmAnd finaly:
chmod +x build-linux.sh
./build-linux.shTo launch x16 PRos, use emulators such as QEMU,Bochs or online emulator like v86. Example command for QEMU:
qemu-system-i386 -audiodev pa,id=snd0 -machine pcspk-audiodev=snd0 -hda disk_img/x16pros.imgYou can also try running x16-PRos on a real PC (preferably with BIOS, not UEFI)
If you still want to run x16-PRos on a UEFI PC, you will need to enable "CSM support" in your BIOS. It may be called slightly differently.
- Open PowerShell as Administrator and run:
winget install nasm
winget install qemu- Add NASM and QEMU to System Path by running:
setx PATH "%PATH%;C:\Program Files\NASM;C:\Program Files\qemu"-
Reboot your PC for the PATH changes to take effect.
-
Run the build script:
build-windows.batNote: Make sure to restart your terminal or IDE after modifying the PATH variable.
- If commands are not recognized, verify the installation paths
- Ensure PowerShell was run as Administrator during installation
- Check if PATH was updated correctly by running
echo %PATH%
- PRoX (Faddey Kabanov) lead developer. Creator of the kernel, command interpreter, writer, brainf, snake programs.
- Loxsete developer of the barchart program.
- Saeta developer of the calculation logic in the program "Calculator".
- Qwez developer of the "space arcade" game.
