This directory contains some experiments in building a RETRO system to run directly on hardware. As a stepping stone, it also includes some builds which require a host kernel, but no standard C library.
Initial Objectives:
- Reuse as much of the existing VM implementation (in C) as possible.
- Don't require a full blown kernel & userland to run
- Work with a completely standard RETRO image
- Minimally viable system: the basic listener (REPL)
- Work on 32-bit x86 systems
Future Goals:
-
Support for more processors
- x86-64
- ARM (32-bit)
- ARM (64-bit)
- RISC-V
- MIPS M4K (PIC32)
Current Status:
-
Working builds w/minimal host dependencies:
- FreeBSD (32-bit, x86)
- FreeBSD (64-bit, x86)
- Linux (32-bit, x86)
- Native (32-bit, x86, multiboot)
