An EVM-based experiment that stores a 1990s game as contract code, verifies its bytes on-chain, and loads it in the browser.

Landing page captured for the 2026-09-17 issue.

Field notes

The project stores a compressed game bundle as multiple EVM contract-code chunks rather than serving it from a conventional host. The ROM contract records pointers and a keccak Merkle root, while the browser retrieves the chunks, rebuilds the tree, inflates the bundle, and only then compiles the WebAssembly. The 24,575-byte chunk size reflects the EIP-170 contract-code limit, and the page offers a six-chunk on-chain spot check.
