Real-time strategy for x86 processors made in assembly.

WEB DOS EMULATOR

• VGA 320x200, 16 colors (DawnBringer palette), 256-color mode
• 2D tile-based, top-down view
• Full keyboard and mouse support
• 16x16 sprites/tiles (2-bit palette compression, 4 colors + transparency)
• Procedural map generation (weighted adjacency rules)
• 128x128 tile map with viewport scrolling
• Double-buffered framebuffer with partial terrain redraw
• RLE image compression for pre-rendered backgrounds
• Sound effects via PC Speaker (IRQ-driven PIT playback)
• Rail system with automatic track orientation and switch logic
• Pod (cart) entity system: moving goods on rails, collision handling
• Base expansion and building placement
• 8 building types: silos, collector, extractor, refinery, lab, radar, pod factory, power
• 3 resource types (white, blue, green): extraction, transport, refinement
• Extractor setup with targeting and resource type selection
• Fog of war with radar visibility expansion
• Radar minimap (satellite view)
• UPX-compressed COM output for DOS
• Bootable FAT12 floppy image (bare-metal + DOS)
• Development tools (vibe coded C):
  • png2asm - convert PNG tilemap to 2-bit paletted assembly
  • rleimg2asm - convert images to RLE-compressed assembly
  • fnt2asm - convert font charset to 1-bit assembly
• All game graphics were made with my own tool: P1Xel Tool
  • Source code: https://github.com/w84death/p1xel-tool
  • Binary included in this repo: tools/p1xel_tool

Boot from a floppy or run from MS-DOS (FreeDOS). Floppy image has game file (game.com), instruction, and bootloader for bare-metal run.

Uses Zig build system (build.zig) with FASM assembler.

Build bootable floppy image (default):

zig build

Build compressed COM file with UPX:

zig build com

Build uncompressed COM file:

zig build com-raw

Run in QEMU:

zig build qemu

Run in Bochs:

zig build bochs

Build jsdos archive:

zig build jsdos
