MSX-Blaster OPL4 - 2MB

MSX-Blaster OPL4 - 2MB

Attention: This product takes about 6 weeks to be assembled, tested and ready to ship


Yamaha YMF278 OPL4 FM/Wave for MSX Computers. Compatible with MoonSound.


New version with 2MB RAM for Samples!! Includes improved high signal noise ratio output circuit.


    The MSXBlaster cartridge is based on the Wozblaster, originally made by Gustavo Iriarte and later reworked by Eugeny Brychov. Unlike the Wozblaster, the MSXBlaster runs with a CPLD chip, thus reducing heat and power consumption. The MSXBlaster can output its audio signal through the MSX audio output (mono) and alternatively through an stereo line-out 3,5mm jack. Furthermore, from revision 2.5 on it includes a high signal-to-noise ratio circuit fix for better audio output.

    For best audio quality use the jack line-out!

    The MSXBlaster features 2MB SRAM to load user samples and 2MB Yamaha YRW801-M General MIDI on board ROM containing 330 mono factory samples.
