Tool family
Save-format utilities for supported retro systems and emulator workflows.
Current catalog
Planned and deprecated records are intentionally excluded from Tool Family archives. Each result still carries its own support and processing state.

Emulator & Retro Tools
Extract the exact fixed-layout Controller Pak 1 byte region from the existing verified Mupen64Plus-Next RetroArch composite save without interpreting or changing game data.
Emulator & Retro Tools
Extract the exact fixed-layout Controller Pak 2 byte region from the existing verified Mupen64Plus-Next RetroArch composite save without interpreting or changing game data.
Emulator & Retro Tools
Extract the exact fixed-layout Controller Pak 3 byte region from the existing verified Mupen64Plus-Next RetroArch composite save without interpreting or changing game data.
Emulator & Retro Tools
Extract the exact fixed-layout Controller Pak 4 byte region from the existing verified Mupen64Plus-Next RetroArch composite save without interpreting or changing game data.
Emulator & Retro Tools
Extract the exact fixed-layout SRAM byte region from the existing verified Mupen64Plus-Next RetroArch composite save without interpreting or changing game data.
Emulator & Retro Tools
Extract the exact fixed-layout FlashRAM byte region from the existing verified Mupen64Plus-Next RetroArch composite save without interpreting or changing game data.
Emulator & Retro Tools
Restore one damaged VMU formatted-card marker byte inside an exact 128 KiB Nexus DCM dump after deterministic four-byte-group normalization and strict filesystem validation.
Emulator & Retro Tools
Losslessly migrate a canonical DexDrive GME card to raw MCR only when every supported wrapper byte is exactly reproducible from fixed constants and the embedded card.
Emulator & Retro Tools
Restore exactly one damaged byte in the fixed little-endian root FAT-location value 254 only when the root marker, physical FAT, directory chain and all other fixed geometry already validate.
Emulator & Retro Tools
Losslessly migrate a canonical VGS/MEM card to canonical DexDrive GME through an exactly preserved raw 128 KiB card state, with source reconstruction and target reopen proofs.
Emulator & Retro Tools
Restore one damaged byte in the documented VMU root FAT-location field inside a Nexus DCM image while preserving DCM byte ordering and independently validating the physical filesystem.
Emulator & Retro Tools
Losslessly migrate a canonical DexDrive GME card to canonical VGS/MEM through an unchanged raw 128 KiB card, with byte-identical GME rollback proof.
Emulator & Retro Tools
Restore exactly one damaged byte in the fixed little-endian root directory-location value 253 only when the physical 13-block directory chain and all other documented VMU invariants already validate.
Emulator & Retro Tools
Restore one mapped DCM byte corresponding to a one-byte defect in the documented VMU root directory-location value after independent normalized filesystem validation.
Emulator & Retro Tools
Restore exactly one damaged byte in the fixed two-byte VMI version value 0 only when the exact 108-byte record, resource-name checksum and all other documented fields independently validate.
Emulator & Retro Tools
Restore exactly one damaged byte in the fixed VMI file-number value 1 only when the exact 108-byte record, resource checksum, version and every other documented invariant independently validate.
Emulator & Retro Tools
Validate a complete DexDrive GME memory-card wrapper and extract its exact embedded 128 KiB PS1 card only when the 123-456-STD marker and every embedded card checksum pass.
Compatibility first
A tool family groups related jobs, but individual file formats and game versions can have different requirements. The individual tool page is the source of truth for compatibility, processing mode, limitations, and verification details.
