Ym2413_instruments.bin !!top!! < Fully Tested >

| Byte | Bits (high–low) | Description | |------|----------------|-------------| | 0 | aa aa aaaa | F-Number low bits (8 bits) — but on YM2413, first byte often contains other params | Wait — actually, the YM2413's internal instrument ROM data is 8 bytes per instrument, but the common 4-byte compressed format is used in some dumps for emulators.

If you can share a hex dump of the first 64 bytes of that file, I can decode the instruments for you. ym2413_instruments.bin

Offset (bytes) : Meaning 0x00 : Instrument 0 (usually user/Rhythm? often unused) 0x04 : Instrument 1 ... 0x3C : Instrument 15 | Byte | Bits (high–low) | Description |

Without the actual binary content, I can't give you the exact values. However, I can tell you the of such a file if it follows the standard YM2413 instrument ROM dump. Standard YM2413 instrument ROM format (4 bytes per instrument) For the built-in 15 instruments + 1 user instrument slot, the data is often arranged as: often unused) 0x04 : Instrument 1

The file ym2413_instruments.bin is a binary file that likely contains instrument parameter data for the (also known as the OPLL) sound chip. This chip is a 4-operator FM synthesis chip used in various MSX computers, Sega Master System (as FM sound unit), some arcade boards, and early PC sound cards.
