"The corrupt bro dances across the NAND, thirteen bytes past the checksum, and the save never knows." 💩

Currently in active development: The first native Switch save editor for Digimon Story: Time Stranger. Successfully achieved direct NAND injection (no bridge required!). Building out advanced features before public release.
🔬 Reverse Engineering Highlights:
- Located Yen value at offset
0x7973(u32 little-endian) in/savedata/0001.bin - Discovered the
fsFsCommit()requirement to prevent silent NAND rollbacks - Built custom hex-scanners to diff save dumps and locate offsets/checksums automatically
PKHeX-NX 🔴⚪️
Public Beta & actively hardening: The first 100% native Switch save editor for Pokémon Scarlet & Violet (Gen 9) — no PC, no save dumping, no bridges. v0.9.5 QoL sprint live; part of the 1,000+ combined downloads milestone across the native save editor portfolio.
🔬 Reverse Engineering Highlights:
- Cracked the Gen 9 SCBlock/SCXorShift32 save structure with SHA256 footer verification and xorpad decryption
- Ported the PKHeX
SpeciesConverterto fix the Paldean ID divergence (Tarountula #917+ now display correctly, eliminating the "Dunsparce imposter" bug) - Built a legality-aware generator: real abilities, manual legal move picker (pulled from real learnsets), growth-correct EXP across all 6 curves, and a 26-ball picker with correct in-game IDs
- Implemented the byte-verified backup + dual-file commit safety pipeline, alongside boot-time crypto sanity checks, SD space validation, and hard Applet-mode memory guards
Shipped & stable: The first 100% native Switch save editor for Animal Crossing: New Horizons — no PC, no save dumping, no bridges. v1.4.0 live with 1,000+ combined downloads across GitHub + GameBanana; v1.5.0 Room Decorations Injector in active development.
🔬 Reverse Engineering Highlights:
- Cracked the AES-encrypted economy integers (Wallet, Bank, Nook Miles, Loan) split across
personal.dat(per-resident) andmain.dat(per-island) - Implemented automatic Murmur3 hash healing so edited saves pass the game's integrity checks on first boot
- Mapped the pocket item table: 8-byte slot records at offset
0x2A00under/Villager0/, powered by a 13,000+ item-name database with native keyboard search - Built the byte-verified backup + dual-file commit safety pipeline (auto SD backup before every NAND write, one-tap ZL rollback) — 1,000+ installs, zero lost saves
"I told my niece I corrupted her island... she dubbed you 'Corrupt Bro'. Restoring the Zelda save sounds complicated so I think I'm going to stop but I'm happy the switch is working again. Again, you're an awesome person for taking the time to help me troubleshoot."

"I need to write up a small 'how to' document for my non-tech-savvy wife... Would you like me to post it here so you can use whatever part of it that you want for helping others?"
— micaturtle, Tech Support Pro & Community Collaborator (After catching a folder naming bug in v1.4.0, they helped fix the release zip and volunteered to write an accessibility guide)
"Can someone please bring native PKHeX on switch with support for all gens... You got all my support my friend!"
— z-shark, Homebrew Community Member (After seeing my ACNH editor, they confirmed native PKHeX-NX was exactly what the community needed for cross-gen Pokémon management)
"OMG Cbreezy! You are the GOAT! I haven't even opened it yet, and this looks AWESOME. :D - the pocket item injection will be awesome! Thank you SO much :D"
— micaturtle, ACNH Modding Community (On launch day of v1.0; later helped fix broken links and volunteered to write accessibility guides)
"I'll definitely be installing this once I get back into my ACNH phase haha, seems like a great addition thank you!"
