MSXgl is a free and open-source C library to create application on MSX using SDCC. The library is built around many modules that implement in an optimized way the different features of the MSX and a cross-platform build tool (Windows, Linux and macOS) that allows to generate in 1-click, the final program in various formats (ROM, MegaROM, MSX-DOS and BASIC binary).

Contents

Containt

The library contains following features:

  • The tool chain works on Windows, Linux and macOS (all needed tools are imbedded for Windows and Linux).
  • Format: MSX-DOS binary, Basic binary, plain ROM (8 to 64 KB) and mapped ROM (ASCII 8/16, Konami, Konami SCC)
  • VDP (TMS9918, V9938, V9958), Sprite, Input (Keyboard, joystick & mouse), Math, String, Draw, BIOS, Real Time Clock, ...
  • Audio chip: PSG, MSX-Music (FM-PAC), MSX-Audio and SCC.
  • Audio format: PT3, ayFX, AT2 (AKG, AKY and AKM), TriloTracker (SCC), WYZ, VGM, ayVGM and PCM-Enc.
  • Boot code: Install cartridge ISR in page 0, install RAM and ISR in page 0, allow BDOS for cartridge program, use trampoline to access function in other segment, etc.
  • Devices: V9990, Ninja Tap.

Formats

From the same C code, MSXgl can generate a binary program usable on MSX in various formats:

  • Plain ROM (8, 16, 32, 48 or 64 KB). #1
  • MegaROM or "mapped" ROM in ASCII-16 format (from 64 KB to 4 MB) or ASCII-8, Konami and Konami with SCC (from 64 KB to 2 MB).
  • Binary for MSX-DOS 1 or MSX-DOS 2 (.com).
  • Binary for MSX BASIC (.bin).
  • Binary for disk auto-boot.

#1 For 48 and 64 KB ROM, it is possible to automatically add an interrupt handler to replace the BIOS one.
