Hey everyone! I've made an account to see if someone can help me with this...

I have a music channel on YouTube and I did a KOF 98-styled remix (with samples from that game recorded through Winamp using the VGM Plug-In and Audacity) and I plan to do more on the future. The thing is that I don't have all the samples I need and the process to extract them is VERY tedious and inconvenient (plus the length and quality of the samples vary too much, sometimes these are short and sometimes these are long). Are there any programs that allow me to extract the ADPCM samples and the Delta-T samples from the Neo-Geo VGZ files in a WAV format or something like that? (specifically those from KOF 98).

You should have a look at these converters.

Those only convert sample data though. You need to split them separately afterwards.
You can run the tools on either the ROMs from the ROM set that contain the sample data or on uncompressed VGMs. (rename .vgz to .vgm.gz and use 7z or WinRAR to decompress them)

My post in that topic also has a few details on how to extract samples from VGMs using a hex-editor. Extracting samples from the VGMs first and running the decompression tools on those extracted samples may reduce DC offsets.

Why not have someone someday create a tool for YM2610/YM2610B sample ripping? Not just for Neo-Geo games, but some arcades by Taito and their secondary developers under their umbrella. Even the first Beast Busters arcade was perhaps the only YM2610 game by SNK that's not on Neo-Geo.

The process isn't different for other games.

also, I have an ADPCM codec (encoder / decoder) here that handles most of the ADPCM formats found in VGM files. I recommend splitting the samples before decoding them (or do a test decode first to get the split offsets) , as ADPCM relies on the decoder state being reset at the beginning of each sample.
