Author Topic: MSU-1 hacks Read times. Kyle Sr. The patch released is a roll your own though and takes a little while to get going because he doesn't supply any of the music. The fun thing is that you can use whatever music you want. I did Radar Love which I'm guessing must be exclusive to the Genesis port since it wasn't in the track listing.

Greg Sr. Rock N Roll Racing soundtrack I downloaded and tried several. A guy on youtube helped me out with a pre-patched MMX file. I don't get it, I never had this problem patching roms in the past. So still trying to get Rock n Roll Racing to work. My only problem im having is the music volume is quite low. Personally im liking the original allot more. Quote from: Greg on January 04,AM.

Be the first one to write a review.This means that high pitched noise can be heard from the MSU-1 audio on a rev-H board. H, where the output is driven by the op-amp. I honestly do not, but I would be happy to record some samples from my Rev F. It should work just fine with the single-supply amp, you just have to remove the series DC-blocking capacitor.

I'll be interested to see the results. I doubt that the omission of the filter would cause a significant amount of extra noise. Possible exception: Aliasing effects occurring in digital capture devices that do not have a low-pass filter on their own inputs.

I can take some measurements later, right behind the DAC and right behind the opamp. All of these frequencies are well above the limit of human hearing so whatever high-pitch noise occurs, being in the audible range it would have been untouched by the filter anyway.

I wonder whether this was a theoretical observation or anybody actually experienced high pitch noise with the Rev. H sd2snes.

The DAC is always on btw, so the noise should be audible with regular games as well. With Rev. There is more audible digital noise, sounding like the CPU "working", when AGND is still connected via a ferrite bead instead of a direct connection.

I fear that some Rev. Hs actually shipped with ferrite beads which might in turn have led to noise. That said, neither revision of the sd2snes should be considered to be anywhere near audiophile standards, you can hear interference with any revision. It is more pronounced with 1CHIP consoles. I think the SNR is somewhere around dB.

Wednesday, January 24, sd2snes and MSU In addition to the size increase, the MSU-1 allows for streaming audio in the same format provided by a CD, namely bit uncompressed stereo audio at a In this blog post, let's talk about the hardware behind the MSU-1 and some of the more interesting hacks available for it. It generates stereo analog audio on the board and sends that audio to the SNES through the the cartridge connector's audio input pins. The only other common cartridge-slot devices which generate audio and interact with the SNES for more than just reading gamepads are the Super Game Boys.

The sd2snes is an open source project, anyone with the skills, tools and hardware can make one. The creator of the sd2snes, ikari, has partnered with krikzz to make "official creator-approved" boards. The publicly available boards have had an interesting revision history which should be documented here : Rev E1 - Initial version made by Krikzz Rev E2 - Older then E2, changes made because ikari was unable to find a source for the voltage regulator used in E1.

Even though it is better to add the filter before the audio enters the Op-Amp, the Op-Amp outputs do not have a filter to perform nearly the same function. Ironically, the pre-H units did have the RC filter stage, but the mod requires the removal of the resistors and capacitors that make up the filter stage. Essentially the filter was removed to make room for the Op-Amp on the rev.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

See the Audio Files page on the wiki. This patch was originally written by Conn He wrote the patch directly in hex, so I disassembled it, and he then commented the disassembly. Beyond the initial commit, further changes may be made to address a few remaining minor issues, as well as to clean up the code and possibly relocate it so it doesn't require expanding the ROM to 12Mbit. In case my edits start breaking things, you can always refer to this commit for Conn79's final version, which should be considered functionally complete.

The Legend of Zelda: A Link to the Past (SNES) - MSU-1 Four Swords Adventures Soundpack (v2.1)

I had just discovered MSU-1 mods a month or two ago, and it was a royal pain getting them working in Higan, but sooo worth the effort, and I wanted to know if I could get them working on RetroPie. It then took a much longer googling session to find out just how I needed to get the files setup to work I eventually found it as an offhand comment buried deep in the bowels of a forum about SNES9x.

I decided to write up a quick guide consolidating my discoveries, in case others were looking for this info. What is an MSU-1 mod? The MSU-1 is a cartridge addon chip similar to the SuperFx chip that allows for many enhancements to SNES games including, but not limited to, full-motion video and CD quality sound by adding up to 4GB yes, 4 giga bytes of storage for extra content.

Chrono Trigger with all the video cutscenes from the PlayStation version inserted. Mega Man X with a new CD quality soundtrack. Emulators, on the other hand, need to be modified to support playback of MSU-1 modded games.

The chip does have some limitations, such as only being able to stream one data track at a time, but it essentially turns the SNES into what it could have been with a CD attachment.

Continue to go back until you're at the Setup Script's first menu. Scroll down to and select "Perform reboot". Select "Yes" on the following dialog. The ROM file. The ROM file may be named program. MSU file that came with the msu-1 patch It might be named msu. PCM audio files. Optional Some MSU-1 mods may come with a save file as well, this may or may not be needed to properly save, depending on the game, so it's typically best to include it.

It will either be a SRM file or save.

You do not need a manifest file, or any. BML files. Including them could break the mod. Save file if present : [rom name]. Place all required files, named as shown above, into this folder.Consequently, it is a part of the game cartridge. Unfortunately for those who would make this mistake and stick to it, that would disqualify the expansion chips listed above as well.

This was, like the SNES, a cartridge-based game console. The Mega CD peripheral added increased storage size and CD-Audio capabilities to it, keeping the rest of the system mostly the same. The MSU1 expansion chip offers up to four gigabytes of data storage in a single stream, which can be used to store, for example, full motion video data. It can not be used as RAM. On the other hand it could be turned around, playing sequenced background music on the SPC and a voice track on the MSU1 during a cutscene.

Their functions are different between reading and writing.

The revision part will be equal to 1, unless a new version of the MSU1 specification is released, which may add more features. This allows selectively falling back to SPC sound. This allows the program to detect availability and as such offer compatibility fallbacks. The currently playing track is stopped.

Sets the audio playback volume on a linear scale. If the play bit is not set, the music is effectively paused. The upper six bits are reserved for future use — they must be set to zero to ensure proper operation.

The audio tracks are This is followed by a bit unsigned integer used as the loop point, measured in samples a sample being four bytes — if the repeat bit is set in the audio state register, this value is used to determine where to seek the audio track to. Creation of audio tracks can be done easily by using the wav2msu tool. Include code for a simple video player? More fun times: a SeekToID routine that, given a table of pointers at the start of the data file, seeks to a specific entry?
