At the end of the round, for any Bits you lost by reasons other than Burn, choose an equivalent quantity of Bits used on your actions that round. You regain the Bits as "ROM Bits" - each round, you must spend them in exactly those same actions, with the exact same targets. Only regular Bits can be lost by damage, burn and so on; as long as you only have ROM Bits, you are considered to be eliminated for game-winning purposes.
