kos-ports's Introduction

KallistiOS

Independent SDK for the Sega Dreamcast
Explore the docs »

Overview

KOS is an unofficial development kit for the SEGA Dreamcast game console with some support for the NAOMI and NAOMI 2 arcade boards.

KOS was developed from scratch over the internet by a group of free software developers and has no relation to the official Sega Katana or Microsoft Windows CE Dreamcast development kits. This has allowed it to fuel a thriving Dreamcast homebrew scene, powering many commercial releases for the platform over the years. It supports a significant portion of the Dreamcast's hardware capabilities and a wide variety of peripherals, accessories, and add-ons for the console, including custom hardware modifications that have been created by the scene.

Despite the console's age, KOS offers an extremely modern, programmer-friendly development environment. Using the latest GCC toolchain, it supports the entirety of C17 and C++20 including their standard libraries, along with support for portions of C23, C++23, Objective-C, and various POSIX APIs. Additionally, KOS-ports offers a rich set of add-on libraries such as SDL, OpenGL, OpenAL, and Lua for the platform.

Getting Started

A beginner's guide to development for the Sega Dreamcast along with detailed instructions for installing KOS and the required toolchains can be found on the Dreamcast Wiki. Additional documentation can be found in the docs folder.

Examples

Once you've set up the environment and are ready to begin developing, a good place to start learning is the examples directory, which provides demos for the various KOS APIs and for interacting with the Dreamcast's hardware. Examples include:

Hello World
Console Input/Output
Assertions, stacktraces, threading
Drawing directly to the framebuffer
Rendering with OpenGL
Rendering with KGL
Rendering with KOS PVR API
Texturing with libPNG
Bump maps, modifier volumes, render-to-texture PVR effects
Audio playback on the ARM SPU
Audio playback using SDL Audio
Audio playback using OGG, MP3, and CDDA
Querying controller input
Querying keyboard input
Querying mouse input
Querying lightgun input
Accessing the VMU filesystem
Accessing the SD card filesystem
Networking with the modem, broadband adapter, and LAN adapter

kos-ports's Issues

Merge Request for libGL not being picked up ?

Hello,

I created a small merge request on sourceforge 5 months ago, but it's not being picked up.
Should I request it in another place ?
https://sourceforge.net/p/cadcdev/libgl/merge-requests/

Thanks,

libtremor is no more available

It looks like svn repo from xiph.org is no more available.
Same for the git repo.

Question About SDL2 support

I’m in a Discord server with one of the core maintainers of SDL, Ryan Gordon, and we were wondering why SDL2 hasn’t been supported yet? I remember years back hacking on Kallistios and seem to recall SDL2 not having an equivalent to a disc reading implementation used but I wanted to verify my findings. If you have any interest in discussing this further, I could link the Discord server and we could try to figure something out with it.

sh-elf-gcc: error: unrecognized command line option ‘-pthread’ when building freetype

Doing make install in the freetype folder gives me the -pthread error each time. The kos-cc version is 9.3.0 so I am unsure why it doesn't build properly. This is the full output of make install if that helps:

Finished processing dependencies for freetype.
File "freetype-2.10.2.tar.gz" is ok.
Unpacking freetype-2.10.2.tar.gz ...

FreeType build system -- automatic system detection

The following settings are used:

  platform                    unix
  compiler                    kos-cc
  configuration directory     ./builds/unix
  configuration rules         ./builds/unix/unix.mk

If this does not correspond to your system or settings please remove the file
`config.mk' from this directory then read the INSTALL file for help.

Otherwise, simply type `make' again to build the library,
or `make refdoc' to build the API reference (this needs Python >= 3.5).

Opus lib

Seems to be broken. I haven't compiled it before so I am not sure it due to the recent update of repos. I just ran utils/build-all.sh and encountered a compiler error:
