Compatibility

  • New versions are compatible with old savefiles.
  • Don't mix versions in multiplayer sessions.
  • Don't mix *.pius files or *.gbfs libraries from different versions.

v1.8.*

New features:

  • Added a new challenge mode when completing the campaign mode 👀
  • Arcade modes now store Dance Grades by index instead of by level. This allows saving different scores for charts that have the same numeric level (e.g. s19-a, s19-b)

Misc. changes:

  • Stage Break = DEATH will now display the life bar at minimum level and ignore BADs in the judgement phase
  • Now the game remembers the page/song when switching between campaign and the challenge (e.g. impossible) modes
  • Bubbles in the Home Screen will 'regenerate' when leaving a submenu
  • Removed pixel blinking effect from the Home Screen

Optimizations:

  • Now charts use static EWRAM to prevent crashes due to allocation failures
  • Updated gba-link-connection to v6.0.3, which fixes potential autopairing issues (e.g. two couples trying to create two separate sessions via Wireless Adapter)

Bugfixes:

  • Fixed a small memory leak after playing a song
  • Fixed a bug with the random number generator that was causing the last value of a range to be ignored
  • Fixed a glitch where the user could enter the "Audio lag" option and navigate to the previous/next option during the transition
  • (v1.8.1) Added small fixes and adjustments to the new challenge mode

v1.7.*

New features:

  • Menu controls
    • demo3
    • Menus can now be navigated using two key layouts: GBA style (new), and PIU style
    • GBA style feels more natural, as it's how most GBA games work (navigate with arrows and confirm with A)
    • The default layout was changed to GBA style, but it can be changed using the Admin menu
  • Single-player Arcade mode
    • demo4
    • Double charts can now be selected directly using the level change buttons
    • Added AutoVelocity, under the Speed hacks mod (replaces Random speeds). AutoVelocity ignores the multiplier and sets a regular scroll BPM for all songs
    • Added Color filter mod (replaces Decolorize), with 16 different filters to alter game's background and sprites
    • Added Bounce mod, which makes the arrows (and/or its receptors) bounce
    • Added AutoMod mod, which randomly combines all mods every 1~4 beats
    • Modified LINEAR and MICRO variants of Jump/Reduce mods to move the game area rhythmically
    • Consecutive charts with the same numeric level now have a subindex to differentiate them
    • Enabled mods are now highlighted to easily identify which ones are in use
    • Added a warning to let users know when the current mods won't let them save their Dance Grades
  • Multiplayer Arcade mode
    • demo11
    • VS mode now makes the winner's life bar bounce during gameplay to enhance competitiveness
    • Now players don't have to set the difficulty level after each song; the game remembers
  • Impossible mode
    • demo12
    • It now uses the AutoMod/INSANE, +1 rate, and mirror steps mods
  • Admin menu
    • offsets
    • Added a menu to set up custom offsets for each song/level. This feature is useful if you're playing a non-tested song pack and encounter an out-of-sync song. Now, you can add +/- 8ms offsets, which will be recorded in the save file and applied when playing.

Engine fixes:

  • This build fixes ~32768 corner cases related to chart reading, increasing overall compatibility (specially with gimmick charts)
  • Added mid-note BPM changes support. This fixes a lot of out-of-sync charts
  • Important ASYNC_STOP (aka setting #SCROLLS to 0) rewrite. This fixes multiple bugs where ASYNC_STOPs caused the chart to end up completely out of sync, with a broken metronome, or with infinite holds
  • BPM changes and arrow predictions are now executed even if the chart has stopped
  • The importer now ensures that every HOLD_START will have a subsequent HOLD_END. Now most of the start events have their duration pre-assigned, so no chart should show broken holds again
  • Events inside WARP sections are no longer ignored by the importer, as they are important for gimmick charts. Instead, these are ignored during the judgement phase, to avoid unfair MISSes
  • Unsupported #SCROLLS segments are now emulated as regular speed changes. It doesn't have the same effect, but it works better than ignoring them. This fixes songs with a broken multiplier
  • MISSes are now judged by timing instead of by their Y coordinate. This is important when using low multiplier / speed values.
  • Using a lower FAST_BPM_WARP constant also fixed some songs
  • Fixed a corner case with fake segments events which caused some fake notes to appear as regular notes
  • Removed frame skip in chart reading code, which fixes some glitches in gimmick charts
  • Fixed a corner case where a Scroll BPM change could be ignored until the player manually adjusts the multiplier
  • Equivalent keys (like RIGHT and B for CENTER) now trigger new keypress events even when the other key is already pressed. This makes single-note trills easier
  • Precision of hold arrow judging was adjusted
  • The default scroll BPM change speed was adjusted (100 => 150) and a lower arrow speed limit was set (1px/frame)

Engine improvements:

  • Added co-op chart support: pump-couple and pump-routine
  • SSC parsing is now more robust, ignoring comments and finding charts using #NOTEDATA:; tags
  • Unsupported S, V and H events are now individually ignored instead of ignoring the whole chart
  • Unsupported negative #SPEEDS are now individually ignored instead of ignoring the whole chart

Optimizations:

  • Optimized IWRAM code, making everything faster and preventing slowdowns in complex charts
  • Reduced memory access and CPU usage during gameplay
  • Updated gba-link-connection to v6
    • Significantly reduced latency in multiplayer sessions (both wired and wireless)
    • Significantly reduced CPU consumption in multiplayer sessions
  • Reduced base ROM size by removing dead gba-sprite-engine code
  • Reduced final ROM size by optimizing space in the PIUS format

  • Added save file validation code

Build process updates:

  • Support for double/multiplayer chart offsets, subindex, and delete keyword in offset.pofs files
  • The importer can now automatically add BOSS levels when creating Campaign builds
  • Fixed some errors with the parsing of chart vs global properties
  • Fixed an error that caused complexity to be zero if the charts didn't have a #LASTSECONDHINT
  • Using a Campaign build with an Arcade library will now show a proper error when running the ROM (instead of crashing)
  • Reusing romid.u32 while changing the song count will now throw a proper error instead of building an incorrect ROM file
  • Fixed make package silently failing when the output ROM file was in use
  • All errors thrown by the importer now have more details

Graphical improvements:

  • Song screen
    • Fake HOLD_FILL notes now look fake (dedicated sprite)

    • Increased demo chart complexity when some of the campaign modes are completed
  • Multiplayer/Connecting screen
    • Added a 'transmitting' animated icon
  • Selection screen
    • DOUBLE mode now has its own color palette, to easily identify what type of charts we're seeing

  • Dance Grade screen
    • Updated winner message in VS multiplayer mode for clarity

Bugfixes:

  • Fixed a random DMA lockup on hardware
  • Fixed a glitch where changing the multiplier before the first SET_TEMPO event would cause the Scroll BPM to be set to 0, making initial arrows appear from nowhere
  • Fixed a glitch where correctly judged arrows would pass through receptors when using the Reduce mod
  • Fixed a glitch during transitions where the Selection screen could show garbage for one frame
  • Fixed a bug where I/O SD blink time was tied to the value of the -now deprecated- Background blink speed setting
  • Fixed a bug related to numeric level synchronization (again) in multiplayer sessions
  • Fixed a bug where SRAM LED blink/ON HIT was also blinking with other player's arrows

  • Fixed a bug where multiplier changes were not synchronized correctly in multiplayer sessions
  • Fixed a bug where pixel blinks in level selection were not synchronized correctly during multiplayer sessions
  • Fixed a bug where using fast-forward in training mode would cause a subsequent multiplier change to be ignored

  • (v1.7.1) Fixed a glitch where the life bar could blink at max level when returning from negative to positive value
  • (v1.7.1) Fixed a glitch where the controls screen was animating one of the center buttons at double speed
  • (v1.7.1) Adjusted the orientation of the R button sprite, which previously had its corner pointing to the left
