Level end

The sequence that closes a level once its goal is reached, often turning what is left, such as time, into points before the next level.

A level ends when its goal is met: an exit reached, a boss beaten, or a field cleared. The game then takes control for a short sequence, tallies a bonus, and moves to the next level.

Super Mario Bros.: The Lost Levels 1986The castle victory sequence (VictoryMode through PrintVictoryMessages) is Super Mario Bros.'s with these changes: on world 8, which world D also uses, VictoryMode runs a second task list that loads the ending from disk; SetupVictoryMode also sets the world's bit in CompletedWorlds and queues the castle-clear music; PrintVictoryMessages loses Super Mario Bros.'s world 8 branch and its victory music, and gains EndCastleAward, which counts the remaining time into points. DrawTitleScreen, which sits in the middle, shrinks to a few instructions that queue a layout held in the program, where Super Mario Bros. copies it out of CHR ROM. PlayerVictoryWalk keeps every instruction; only its addresses and one branch's distance differ.Code
RunStarFlagObj through OffscreenBoundsCheck are Super Mario Bros.'s with these changes: RunStarFlagObj sets off fireworks when the timer's last digit matches the coin tally's, where Super Mario Bros. matches the timer's last digit against 1, 3 and 6, and adds its points to the one player's score; MovePiranhaPlant moves red piranha plants (the patched palette) every frame; BalancePlatform leaves a platform alone when its partner is no balance platform; OffscreenBoundsCheck treats upside-down piranha plants like upright ones. FirebarSpin is byte for byte the same, and the moving platforms differ only in their addresses.Code
Felix the Cat 1992$33 is the stage index. A stage ends at $FA20, which adds 1 to it once the clear flag ($03B7) is up and the tally has run the timer down to 000. In the 1625M replay it reads 0 in the first stage and counts up to 22 in the last.Code
Three instructions in the ROM store to the clear flag $03B7. The stage load clears it; the exit test in the fixed bank sets it from Felix's x (felix-the-cat/exit-threshold); and a routine in PRG bank 12 sets it when a countdown at $042B reaches 0.Code
Every frame of play until the clear flag $03B7 is up, the game subtracts $32 and the stage's bound ($BB:$BD) from Felix's x and sets the flag when the result is at least $F0. A stage ends when Felix's x reaches its bound plus 290; in the first stage, whose bound is 3,848, that's x 4,138.Verified
The fixed bank's exit test reads Felix's x and the stage's bound, never the scroll. For example, walked a second into the first stage and placed 6 px below the scroll value, near the right edge of the screen, Felix doesn't clear the stage: the camera re-centers on him the next frame, and the clear flag stays at 0.Verified
KAGE-008's rejected TASVideos submission 6487 plays Dragon Co.'s unlicensed Felix the Cat, a different game from Hudson's, and ends levels "if the player is close to go off-screen to the right". The judge, Maru, adds that the player only has to jump "as much as possible to get to the right of the screen" and reports a test file saving 855 frames in level 1.Web
Replayed in FCEUX, Randil's 1625M movie passes 23 stages in 9 worlds of 3, 3, 3, 3, 3, 2, 2, 1, and 3 stages. For each stage the table gives the frame play starts (game mode $28 reaches 5) and the frame the clear flag goes up; the last stage runs to the movie's end at frame 81,074.Our research
