its a fork of the demo game from gbstudio plus some custom assembly to implement sha254. I followed this guide (linked) to learn the assembly lang for gameboy. You could flash right it to a real physical gameboy cartridge. other questions?

I did a quick video demo of setting up the Tangem hardware wallet from scratch. Hands down the easiest cold storage solution I've ever used: under two minutes to set up the whole thing, super easy to access. And you don't even need a seed phrase. Dare I say boomer-proof? 👴

We often hear folks calling Ledger a cold wallet. We get it – your device keeps your private keys offline for you. The thing is, you can do more with your Ledger. Unfurl to hear why we prefer to think of Ledger as a signing device instead of a cold wallet. A thread 🧵:

NO SEED PHRASE ❌ Your wallet shouldn’t begin with 12 words that can be stolen. In this video, I’m creating a MarvelX wallet using a PQC Vault File — no seed phrase, no screenshots, no clipboard leaks. The PQC Vault is a 320KB file made of algorithmic combinations based on NIST-approved Kyber & Dilithium. No human-readable secrets. No single point of failure. Just a quantum-safe vault + your identity. This is what the future of self-custody looks like: •No seed phrase to lose •No words to phish •Post-quantum cryptography •True zero-trust onboarding Seed phrases were built for 2013. Attackers, malware, AI and quantum computers are built for 2030. MarvelX is coming to fix that. 🛡️ Watch how a wallet is born in the post-seed era. #MarvelX #PostQuantum #CryptoSecurity #SelfCustody #WalletReimagined #PQC #Web3 #Privacy Solana

Been building a whiff punish trainer for 3rd Strike. It makes the opponent walk around, then RNG presses a button of your choice at a range where it will whiff on whoever you pick. Also auto detects who p2 is so it adjusts teh data set.
