We have a new ROM for the MSX audio upgrade board. This new rom ensures better compatibility with Compile disk based games, support for loading programs from hard disk and configurations with slot expanders and multiple hardware configurations. Some users experiences lock-ups in some cases. We tested these configurations with a real Panasonic MSX Audio cartridge and we experienced the same problems. It’s safe to say that our new ROM is now more compatible than the original MSX audio ROM! We also included the default Philips Music Module program in the same rom. Pressing ESC during boot will start the default Philips Program. Pressing TAB during boot will disable the ROM completely. Because the new ROM is twice the size of our original rom some adjustments on the PCB are also necessary. Existing users who bought their expander PCB from SuperSoniqs may apply for the new ROM and needed parts without additional costs. Please contact info@supersoniqs.com for details. All new orders will go with the new ROM and adjustments to the PCB, starting today.
