Firmware for snes emulators
SD2SNES PCB Revision G was a quick fix for this, boosting MSU-1 audio to the correct levels but introducing some noise. SD2SNES PCB Revisions A-F have slightly lower audio output. There are a few differences in the audio circuit of the SD2SNES revisions: If your version is older, there’s actually a modification you can perform to improve the output. If you have Rev.H or newer, you can skip this section.
#Firmware for snes emulators mod#
While no physical MSU-1 chip was ever created, the code was integrated into a few emulators, as well as the FXPak Pro, allowing full CD-quality audio through real SNES hardware!!!Īudio Mod for OLD revisions (No FXPak’s or SD2SNES “Pro’s” have ever required this):Īll revisions of the SD2SNES starting with “H” and later (and every version of the FXPak Pro) already have a great-sounding audio circuit. Well, this is essentially the exact same thing, but for the SNES and only for patched roms.
Also, the extra storage space of a CD allowed for FMV playback, within the restraints of the Genesis’ processing power. It’s a homemade “enhancement chip” created by Near that allows for CD-quality audio on a SNES.Ī good way to think of it is like this: Remember the SegaCD? The graphics were pretty much the same as the Genesis, but the music played directly off the CD allowing for the music to be extremely high quality. The FXPak Pro supports something called “MSU-1 Audio”, which stands for ” Media Streaming Unit revision 1″. The latest official Firmware can always be found here: In fact, it’s actually easier to list the incompatible games, which is exactly what Ikari has done on his website:
The FXPak Pro is the most compatible of all the SNES ROM carts currently on the market. It’s compatible with pretty much the entire SNES library, supports instant load times and includes support for “MSU-1 audio” via its Cyclone V FPGA. The FXPak Pro (formerly known as the SD2SNES) is a Super Nintendo / Super Famicom cartridge that plays games from an SD card, referred to as a “ROM cart”.
