Many front-ends and ecosystem configurations still query the historical archive file definitions.
Power down the unit completely, disconnect power for 30 seconds, and turn the system back on. dl 1425bin upd
The 1425 profile is incompatible with current hardware revision. Verify machine model spec sheet before execution.
To avoid this, you have two options:
The file is a critical BIOS component for MAME (Multiple Arcade Machine Emulator), specifically required for the QSound audio hardware used in Capcom Play System 2 (CPS2) games like Street Fighter Alpha , Marvel vs. Capcom , and The Punisher .
Historically, emulators used a high-level simulation of sound. However, as of version 0.200, the MAME project shifted toward a more accurate "High-Level Emulation" (HLE) of the QSound chip, which requires this specific ROM. : The architecture split further

However, arcade preservationists executed a precise on Capcom's proprietary physical audio chips. Decapping involves physically dissolving the chip's outer packaging to read the internal digital data directly off the silicon wafer.
