# Unlimited lives in River Raid

Claude, connected to Ghidra through an MCP server, analyzed an unlabeled Atari 8-bit ROM and found the code that decrements the player's lives.

Result: Replacing one byte ($88 to $EA, DEY to NOP) kept the lives counter fixed at 3 when tested in an emulator.

## How it was set up

Claude connected to Ghidra via the open-source GhidraMCP server and Ghidra extension. The author renamed the ROM to a.rom and picked only the 6502 CPU.

## Worth knowing

Claude could not rebase memory or patch the binary, so the author did both manually. It also misidentified the game.

## Evidence note
