# Cross Compiling configuration for the Sega Dreamcast
|
|
# https://dreamcast.wiki/Using_Ruby_for_Sega_Dreamcast_development
|
|
#
|
|
# Requires KallistiOS (KOS)
|
|
# http://gamedev.allusion.net/softprj/kos/
|
|
#
|
|
# This configuration has been improved to be used as KallistiOS Port (kos-ports)
|
|
# Updated: 2023-12-24
|
|
#
|
|
# Tested on GNU/Linux, macOS and Windows (MinGW-w64/MSYS2, Cygwin, DreamSDK)
|
|
# DreamSDK is based on MinGW/MSYS: https://dreamsdk.org/
|
|
#
|
|
# Install mruby for Sega Dreamcast using the "mruby" kos-port.
