Description

The MSX-Blaster OPL4 is a MoonSound-compatible cartridge manufactured by 8bits4ever.

It is actually based on the Wozblaster, originally made by Gustavo Iriarte and later reworked by Eugeny Brychov.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 first version had 1MB SRAM, but it has been upgraded to 2MB since version 2.

Official price: €100.00
