Contrary to intuition, even High-Level Emulation often requires the original binary. Why? Because the game’s main CPU (the 68000 or Z80) does not send high-level "play music" commands. It sends raw data blocks intended for the DSP. The HLE engine must parse that data. To understand the structure of that data—memory addresses, sample rates, loop points—the emulator developers must reverse-engineer the binary. In practice, most emulation users must source this

Thus, dl-1425.bin acts as a decryption key for the audio stream. Without it, the HLE engine cannot recognize where a sample starts or ends, resulting in silence, white noise, or crashes. Because the game’s main CPU (the 68000 or
