RAM address 03F0 keeps track of the number of blocks hit, though no routine ever reads the value stored here. This behavior is left unchanged in the Japanese Super Mario Bros. However, this is not the intended behavior, and is actually the result of a bug! The eggs are supposed to be thrown out relative to the player's speed, Lakitu's speed, the player's position, and a pseudo-random value, as well as bounce off of any blocks or walls that they hit on the way down. The Spiny eggs are thrown by Lakitu in a simple straight-down way, with no horizontal movement whatsoever.

This setting is also used in cloud bonuses and World 4-2's vine warp zone, however the current level's timer is still valid there, so this setting goes ineffective.Д¬oin rooms (such as the one in World 1-1), water bonus (World 5-2) and World 8-4's water portion, however, use setting 1. While this setting is used by intros (such as the beginning of World 1-2), the game doesn't actually use the setting, since it completely disables the timer in these levels. Likewise, the timer starts at 000 (causes instant death on normal levels) if this setting is set to 0 ( 00xxxxxx). The timer starts at 200 if this setting is set to 3 ( 11xxxxxx), though no valid level actually uses it. The upper 2 bits of the first level header setting byte determines the starting timer.

This game cemented Mario as the most famous plumber to grace televisions, with compelling gameplay, catchy music, and good graphics. was, and still is, probably the most well-known and biggest-selling NES platformer ever, especially since it was included with most NES units either by itself or with Duck Hunt. See also: the todo on the prerelease page If the Koopa Shell 1-Up trick is a glitch, then what causes it? Also, if it is just a side effect of combos for stomping multiple enemies in a row - is there a place in the normal game where this is possible without glitches? The same question applies for hitting multiple enemies in a row with a Koopa Shell (which can give you infinite 1-ups too, in hard mode).

Stuff from the (partial?) source code for the SMAS port game, from the Nintendo leak.There might be more unused enemies and objects.(oddly, the underwater levels come first - perhaps maybe the underwater levels were originally the 'cloud levels' mentioned in various interviews?)
