Build tool
From MSX Game Library
The Build tool is the MSXGL script that will create your final program for MSX.
It is fully configurable by the user. For example, it is here that we can choose whether we want our game to be available in ROM, MSX-DOS or BASIC binary format. Or if our program should be MSX1 compatible or only MSX2+ for example.
The Build tool is written in JavaScript and executed via Node.js. All the programs needed to run the script are available in MSXgl and the user does not need to install anything.
Build tool is started from the project directory via a script that depends on the platform:
- On Windows, run build.bat,
- On Linux, run ./build.sh.
See the example or template project for an actual use case.
Contents
Configuration
The Build tool configuration's parameters are defined in the engine (engine/script/js/setup_global.js) and can be overwrite by the user at two levels:
- The default configuration (projects/default_config.js), commun for all the projects.
- The project configuration (projects/myProject/project_config.js), specific for a given project.
The value of the parameters redefined in a higher level replaces that of a lower level.
Some parameters can be overwrite as command-line parameters (see Command-line overwrite section).
The order of priority is: Command-line > Project config > Default config > Engine config.
Build parameters

Command-line overwrite
The followings parameters can be overwrite from command-line parameter when the Build tool script is invoked:
Parameter | Syntax | Desc. | Example |
---|---|---|---|
Target | target=XXX | Overwrite program target type | target=DOS1 (for MSX-DOS program) |
Machine | machine=XXX | Overwrite target machine | machine=2P (for MSX2+ machine) |
ProjName | projname=XXX | Overwrite project name | projname=mygame |
ROMSize | romsize=XXX | Overwrite mapped-ROM size | romsize=256 (for 256 KB mapped-ROM) |
ROMDelayBoot | delay | Force the delay boot parameter to true | delay |
InstallRAMISR | ramisr | Force the install RAM ISR parameter (switch page 0 to RAM and intall ISR there) | ramisr |
For example:
..\..\tools\build\Node\node.exe ..\..\engine\script\js\build.js target=%1
Allows you to overwrite the build target from the command line. E.g.: build DOS2 (MSX-DOS2 application) or build ROM_48K (48 KB plain-ROM cartridge).
Misc
Previously, the Build tool was written in Windows batch format. Here is a guide to convert the configuration files to use the new Build tool. ⚠️ Old batch version of the build tool is no longer supported start from MSXgl 1.0.1 version. Please update your project configuration.
