+
+
+
+
+### Earthworm
+Makes the arrows wave back and fourth as they scroll to the top.
+

+# Pump it Up NX Absolute
+
+This document collects various information about the game itself.
+
+## Trivia
+
+* Release: December 2008
+* USB player profiles from NX2 can be carried over and are extended by the game on first load. NXA
+USB profiles are not backwards compatible with NX2.
+* The original game only allows special brand of usb thumb drives. Other drives are not accepted by
+the game. Profiles were managed and uploaded by the player using a proprietary software called
+"PUMBI" which is no longer supported.
+
+# Game modes
+
+* Arcade Station: Separated into 3 channels. Each channel contains songs with chart difficulties Normal, Hard, Crazy,
+Freestyle, Nightmare
+ * New Tunes
+ * Banya
+ * K-Pop
+ * Pop
+* Training Station
+* Brain Shower: Solve puzzles/quiz questions while playing a song
+* Special Station: Full versions, remixes and another step (charts)
+* World Max: Clear missions to unlock further locked missions and content in Special Station
+
+## World max guide and unlocks
+
+Either take a look at the `missions.txt` file which is either located on the compressed file system
+of an original drive or in the `game` data folder of some data release, or use
+[blood618's guide](guide/nxa.pdf) which was published on ph-online back in the days.
+
+### Missions.txt
+
+Take a look at the `missions.txt` file which should easily reveal a bunch of useful information
+already like mission conditions.
+
+### blood618's guide
+
+See [here](guide/nxa.pdf).
+
+### Unlocks sourced from disassembly (icex2)
+
+Sourced from the disassembly of the 1.10 build.
+
+The game takes any saves from NX2 and converts them to NXA saves. Internally, this is done by
+simply appending new data to the existing NX2 save file format. However, this does not keep the
+format (backwards) compatible at all, as some missions have changed as well as how unlock flags
+are processsed by the game, e.g. barrier unlock flags are entirely re-mapped.
+
+#### Barriers
+
+*EFxxx* identifiers are the official "mission step" identifiers used in the game's code and
+assets. You can use these to search for the mission entries in the `mission.txt` file.
+
+Total of 10 barriers to unlock. IDs denote game internal identifiers for each barrier.
+
+* Yellow (Barrier ID 7)
+ * Clear (nearly) all missions in Ladania
+ * Mission step IDs: EF450 (Beat the Step / Ladania) to EF464 (Devil Castle / Ladania) without EF458 (NXSB / Ladania)
+* Dark Green (Barrier ID 5)
+ * Clear (nearly) all missions "on earth" which includes missions of the lands Caelum, Luman Ocean, Ladania, Pandonus and Arowahi
+ * Mission step IDs: EF400 (Arriving / Caelum) to EF487 (More-Powerful 2 / Arowahi) without EF432 (* Yasangma 2-2 / Luman Ocean)
+* ??? (Barrier ID 10)
+ * Clear all missions in Caelum
+ * Mission step IDs: EF400 (Arriving / Caelum) to EF424: Appear / Caelum
+* ??? (Barrier ID 8)
+ * Clear Turn Turn Turn! / Pandonus (EF445)
+* ??? (Barrier ID 13)
+ * Clear She Likes D / Pandonus (EF440)
+ * Clear Lighthouse / Arowahi (EF483)
+* ??? (Barrier ID 11)
+ * Clear Wook! / Arowahi (EF466)
+ * Clear Turn Turn Turn! / Pandonus (EF445)
+ * Total world max clear percentage > ~61% (the math in the code is super weird resulting in a non-rounded floating point value)
+* ??? (Barrier ID 6)
+ * Clear More-Powerful 8 / Evgeneia Geist (EF599)
+ * Clear WormHole / Dream's Kyma (EF598)
+ * Clear WormHole / Stella's Maya (EF597)
+ * Clear Galaxy / Infiniti Musica (EF596)
+ * Clear * Ehne 2 / Infiniti Musica (EF595)
+ * Clear ForWamm / Infiniti Musica (EF594)
+* ??? (Barrier ID 4)
+ * Clear Remember Me 4" / Parafora Psychi (EF631)
+ * Clear Space City 2 / Parafora Psychi (EF632)
+ * Clear WormHole / Stella's Maya (EF636)
+ * Clear Dead End 2 / Cosmos Spatium (EF637)
+* ??? (Barrier ID 12)
+ * Either have it already unlocked + some unknown condition
+ * Or get more than 19% on World Max
+* ??? (Barrier ID 9)
+ * Accumulated clear percentages (see profile overview on USB load) of World Max, Arcade Station,
+ Brain Shower and Special Zone >= 40%
+ * Which means that achieving >= 40% on one station alone, e.g. World Max, also works
