If you read SMWC, you'd see I'm making a utility where you can import wave files into SMW.
http://smkdan.eludevisibility.org/other/swmws12.rar How it works: You start with 0xFE0 bytes of free space and you delete existing samples from the game / insert .wav files into it. You can have different size files since it modifies the pointer tables as you go. It's in a crude stage but I had no problem getting samples in game running. There's no support for looped samples at the moment, but it's only 3 days old. The first time you use this, you'll be prompted to point to some free space. You'll only be asked once. This is so it can use the vacant space in the SPC RAM while also making room for the extra bytes it uses. This uses snesbrr for all the conversions. Credit to DMV27. Any thoughts? |

Judging from that screenshot, it's super awesome.
Music editing was a big leap in SMW hacking, but wave modification is an incredible addition! Can't wait to see hacks with even superior music than before. Great job!! ____________________ |

This is exactly what I wanted for a long time! Thank you so much! ____________________ |

Thanks for the feedback.
blackhole89: Modifying the ADSR settings and such would be very useful here...It's definitely a priority for a possible new feature. I never examined N-SPC that much, but I assume for every instrument / SFX command there is a table of ADSR data to use for it, a sample # along with any special effects like pitch sliding (springboard). I'll try out bSNES sometime and see how it pulls the data that end up in the DSP settings. And I realised I was already crossing bank bounaries with over 32,768 bytes of data. This time, EVERYTHING (RATS tag, my extra bytes and all SPC data) fits in one bank. You need to at the prompt insert the data into a bank boundary. http://smkdan.eludevisibility.org/other/smws13.rar Edit: on that note, I started collecting data on the SPC code. For the coin sound you hear on reset, it fills $60-$67 on the DSP end which sets all the writebale per channel settings. It comes from a table at $5570 in SPC RAM and is indexed by multiplying an input varable by 9 (the remaining byte is used for something else). I see from the ROM that it's A6B bytes long. |

I made an update which has it updated the envelope, base pitch and stuff for SFX. It expands the "sample map" to 256 bytes by moving some stuff around. The next step for me is making an editor for the SFX commands of $1DFC / $1DF9. Does what you see there line up with your presonal knowledge? I messed around with it a bit and it sounds like I got it right to me. http://smkdan.eludevisibility.org/other/smws18.rar |

) is editing the ADSR data in the respective engines' actual sample entries (I can imagine beta N-SPC in SMW uses a very similar to the final version system). Either way, good job.
