pcm files to also match the name of your MSU1 patched ROM and MSU data file, usually followed by a dash or underscore and the track number, without any leading 0's (e.g. alttp_msu1.sfc & alttp_msu1.msu).īE SURE TO DISABLE HIDDEN FILE EXTENSIONS

Rename this file to match the name of your MSU1 patched ROM (e.g. If you don't have this file (as is sometimes the case with audio-only MSU1 hacks), you can simply create a blank file with the correct file name and extension. This file might be named msu1.rom, but more commonly it will end with the. Instead, they rely on your files following a specific naming format in order to detect the presence of the MSU1.

The SD2SNES (FXPak), Snes9x, BSNES Plus and MiSTer do not use a manifest file to enable MSU1. SD2SNES (FXPak) / Snes9x / BSNES Plus / MiSTer Now that you have a patched ROM, the next step depends on which emulator/flash cart you are using. A great source of known good headerless ROM dumps is the 'No-Intro' ROM set. Base ROMs used for MSU1 patches are generally headerless.

#SNES9X BAD CHECKSUM PATCH#

BPS patches require a specific ROM checksum, so you cannot apply a BPS patch to a ROM that it wasn't intended for, but with IPS patches you can apply them to any ROM, so extra care is required to make sure the correct base ROM is used or the game will not work.

This is where the code will play the SPC audio from the original game if there is no PCM file detected for that particular track, but it's still good to check that the patch was applied successfully and that the game runs instead of resulting in a black screen or a crash, especially if your patch was in the. At this point the audio most likely won't be working, unless the patch has been coded with what we call 'SPC fallback'. Now that the patch is applied, you can test that the patching process was successful by loading the patched ROM in your emulator or flash cart of choice. You can apply these patches to your original ROM file using Floating IPS (aLttP Randomizer users, skip this step, the patch is already applied by the Randomizer website). Once you have extracted the files, you should have a patch file (usually either. zip/.7z/.rar file, which you'll need to extract. Otherwise, you have probably downloaded a. msu1 extension, see the section below on using Mercurial Magic. If you have downloaded one large file named with a. Audio editors should always endeavor to source high quality, lossless audio files for use with MSU1 hacks, otherwise the lossless audio capability of the MSU1 standard is wasted. If the original audio source was low quality, such as a bad YouTube rip or low-bitrate MP3 file, then MSU1 is only going to sound as good as the original audio source. MSU1 is only playing the audio files that it is given. Also, it's possible that the audio files are simply very poor quality, sounding terribly compressed or otherwise just 'bad'. If you're wondering why this happened, I wrote up an explanation of the problem here.

Try looking here or here for properly normalized audio tracks, but the recommended option is to update your ROM with the very latest patch and audio files from the relevant game article in the MSU1 hacks database here. If the audio files are too loud and sound distorted, the files may have been boosted for use with older versions of MSU1 hacks and you need to find audio files that have been properly normalized. If you ARE experiencing sound problems, there are a couple of potential causes. Unless you're talking about actual audio problems with the files you've downloaded, see directly above. The original game is still there for you to play and enjoy. Nobody's forcing you to play MSU1 hacked games.

See below for a full explanation of these files.īut. It also may, or may not, require a manifest file depending on which emulator you are using. Playing an MSU1 game requires several files, including a patched ROM, an MSU data file and several PCM audio files. They are not supported by ZSNES or old Snes9x forks such as Snes9x-2010 or Snes9x-next, or by Krikzz's Super Everdrive flash cart. MSU1 ROM hacks are supported in higan, various BSNES forks, Snes9x v1.55 and up, ikari_01's SD2SNES (now known as the FXPak) flash cart and MiSTer FPGA. This allows ROM hacks to replace the background music of games with high quality versions that can be seamlessly looped, stream data not already contained in the ROM file and even play full-motion videos. This 'chip' enables playback of CD quality lossless audio (16-bit, 44.1kHz), as well as addressing up to 4GB of data, far more than a typical SNES cartridge could ever hold. MSU1 is a custom coprocessor much like the DSP chips used in games like Super Mario Kart or Pilotwings, designed by byuu/Near, the author of BSNES and higan.
