Neocore

Neocore is a library and toolchain for developing on Neo Geo CD.
It provides high-level functions over Neo Dev Kit and DATlib 0.2, and includes tools and code that can help with projects on this platform.
The library is mainly tested on Raine and MAME emulators and is compatible with Windows 10 and Windows 11 for building.

I share my tools and my code, these could possibly help your projects on this platform.

Features

• High-level functions for Neo Geo CD development
• Tools and code to assist with projects

Build and run (with Mame) an included example

cd samples\hello
.\mak.bat run:mame

Mak rules

Warning: The mak script overrides the path environment variable during compilation.
If you encounter any problems after using it, simply close and restart a new command terminal.

• Clean the builded resources

.\mak.bat clean

• Build sprites

.\mak.bat sprite

• Build the program

.\mak.bat

• Build the ISO file

.\mak.bat iso

• Run with Raine

.\mak.bat run:raine

• Run with Mame

.\mak.bat run:mame

• Delivery ISO

.\mak.bat dist:iso

• Delivery MAME

.\mak.bat dist:mame

Hot reload

cd samples\hello
.\mak.bat serve

Wait for the emulator to run and edit samples\hello\main.c.
Now, remove loggerInfo("DAVID VANDENSTEEN"); (for example).
Save the file.

The hot-reload process will rebuild & run your project automaticaly.

Some problems currently:

• The process is not a real watcher (the rebuild is triggered only if the folder size change)
• When you break this process, path is not restored in the current terminal (close & reopen a new terminal)

CDDA

cd samples\CDDA
.\download-assets
.\mak.bat run:mame

In the emulator, use joypad right and left to change audio track.
See .\samples\CDDA\project.xml for understanding how to set the audio file.

Create a project

With powershell (you need to "be" in neocore folder root path)

$project = "c:\my-git\myGame"

• Replace c:\my-git\myGame with your real path.

xcopy /E /I src-lib $project\neocore\src-lib; copy manifest.xml $project\neocore; copy bootstrap\.gitignore $project\.gitignore; xcopy /E /I toolchain $project\neocore\toolchain; xcopy /E /I bootstrap\standalone $project\src; notepad $project\src\project.xml

Compile and run it

cd $project
.\mak.bat run:mame

See .\$project\project.xml
for settings.

DATlib assets (in progress)

For making your own graphics, see the DATlib ref available here: (you need to building a sample for init build folder)

.\build\neodev-sdk\doc\DATlib-LibraryReference.pdf

The DATlib Framer tool is available here:

.\build\neodev-sdk\m68k\bin\Framer.exe

The DATlib Animator tool is available here:

.\build\neodev-sdk\m68k\bin\Animator.exe

Compiling the lib (necessary if you develop Neocore lib)

cd src-lib
.\build-neocore.bat -gccPath ..\build\gcc\gcc-2.95.2 -includePath ..\build\include -libraryPath ..\build\lib

This script override path environment variable during the compilation.
its avoid collisions with other bin, sdk, gcc...
If sdk was not found, build a sample (with mak script) to initialize cache (sdk will install in build folder).

Pull or checkout another branches

BE CAREFUL : You need to remove build folder .\build for supress cache files before compiling a project
