I'm dropping the samples labeled by ROM ID. As you can see they have done weird stuff with samples 00-07 that are really tiny (but valid I've checked) and samples 08-0F that are dummy.
If anyone would be kind enough to label them and post an updated list I would really appreciate it but it's also something I could do but with more struggle! you could probably listen to them in FF3usME or anothe rBRR editor. Problem is my music instrument English sucks bad I can only say
flute, guitar and banjo..
