KallistiOS is able to produce executables that can run on the Sega Naomi arcarde boards.

== Prerequisites ==
* if you want to use GLdc, you need recent GLdc code (you need at least commit [https://gitlab.com/simulant/GLdc/-/commit/b1223cfd1cc6a829c8acccc28220e15b5383522f b1223cfd] of 03 feb 2024)
* download (git clone) kos & kos-ports into separate folders, eg /kosnaomi & /kos-portsnaomi
* adapt the following in /kosnaomi/environ.sh:
     KOS_SUBARCH="naomi"
     KOS_BASE  <- point to your naomi kos folder
     KOS_PORTS <- point to your naomi kos-ports folder
* Build these /kosnaomi & /kos-portsnaomi
* if you want to use raylib, you need recent raylib4Dreamcast code (you need commit TODO of 04 feb 2024)

== Compilation to a .ELF ==
Example compilation for a raylib example:
* Go to the folder that contains your example, eg:
     cd /opt/toolchains/dc/kos-portsnaomi/raylib4Dreamcast/samples/shapes/basic_shapes
* source the environ.sh of your naomi folder:
     source /opt/toolchains/dc/kosnaomi/environ.sh
* build the .elf for Naomi:
     make

== Converting an .ELF to a .DAT to send to a Naomi DIMM ==
* Convert your Naomi-built KOS .ELF to a .BIN file:
     /opt/toolchains/dc/sh-elf/sh-elf/bin/objcopy -R .stack -O binary raylib.elf raylib_nao.bin

* convert your Naomi .BIN to a .DAT file:
     /opt/toolchains/dc/kosnaomi/utils/naomibintool/naomibintool build raylib_nao.dat -d DEVELOPERNAME -t GAMETITLE -b raylib_nao.bin

== Send your .DAT file to a Naomi DIMM via ethernet ==
* Assuming the IP address of the Naomi is 192.168.1.202:
     /opt/toolchains/dc/kosnaomi/utils/naominetboot/naominetboot -t 192.168.1.202 -x raylib_nao.dat -a

== Send your file to a Naomi via a serial cable ==
If you don't have a DIMM board, or just want to use dc-tool-serial to upload a Naomi .elf via a serial cable, you need:
* a custom bios containing dc-load-ser
* recent KallistiOS code (you need commit [https://github.com/KallistiOS/KallistiOS/commit/d059b922625b6fd1f05dac4381b48d0ba571650b d059b92] of 04 feb 2024)
* upload the .ELF via your regulat dc-tool-ser command, eg:
     dc-tool-ser -b 1562500 -t /dev/ttyUSB0 -x raylib.elf
