# Millfork
A middle-level programming language targeting 6502-based, 8080-based, Z80-based and 6809-based microcomputers.
For binary releases, see: [https://github.com/KarolS/millfork/releases](https://github.com/KarolS/millfork/releases)
(latest: 0.3.30).
For build instructions, see [Build instructions](./COMPILING.md).
## Features
* high performance, due to being designed and optimized for 8-bit microprocessors
* multiple targets:
* Commodore 64 (the primary target)
* Commodore 64 with SuperCPU (experimental, incomplete and very buggy)
* other Commodore computers: C16, Plus/4, C128, PET, VIC-20 (stock or with RAM extensions)
* other 6502-based machines: Famicom/NES, Atari Lynx, Atari 8-bit computers, BBC Micro, Apple II+/IIe/Enhanced IIe, Atari 2600 (experimental), Commander X16 (experimental)
* Z80-based machines: ZX Spectrum 48k, NEC PC-88, Amstrad CPC, MSX, TRS-80 Model 1 and 3, Robotron Z1013
* CP/M
* Game Boy (experimental)
* Tandy Color Computer (experimental)
* MS-DOS (very experimental, via 8080-to-8086 translation)
* multiple supported target processors:
* well supported: MOS 6502, Ricoh 2A03/2A07, WDC 65C02, Intel 8080, Intel 8085, Zilog Z80
* reasonably well supported: Sharp LR35902, CSG 65CE02, Motorola 6809
* partially supported: Hudson Soft HuC6280, WDC 65816, Intel 8086
* inline assembly
* simple macros
* pay only for what you use: not a single byte of memory is used unless for code or explicitly declared variables
* a simple memory model that avoids using the stack
* multi-pass whole-program optimizer (that will even optimize your hand-written assembly if you ask it to)
* support for multi-file programs (Commodore only) and banked cartridges
