Bitcoin News said in a post on X that a proof-of-concept built by @DesobedienteTec has successfully run SeedSigner on the R36S handheld game console, turning the device into a stateless Bitcoin transaction signer. The post described the setup as a way to use low-cost consumer hardware for Bitcoin signing rather than a purpose-built device. According to the same post, the R36S sells for about $40, does not include a wireless chip, and comes with two MicroSD card slots. Bitcoin News also noted that the handheld can emulate Nintendo, SEGA, PSP, and PS1 games. No other technical details were disclosed in the source provided.
