v1.11.*

New features:

• Rumble now works on mGBA. The new default rumble options give more consistent results with different cartridges
• Added a Progress screen that displays some stats and game completion %
• Added a Shuffle mode to Arcade builds
• Added 4-digit support for combo and score numbers
• Grades obtained in Campaign mode are now saved into the Arcade mode as well
• When scrolling through Arcade mode, chart levels are now selected in a more intuitive way: the game will remember the last selected level (e.g. s19) and try to select the closest chart for each song, until the level is changed again

• Added the song, artist, and level to Dance Grade screen for score posting

Engine improvements:

• Now the engine doesn't have to measure how many frames each beat takes, it receives that information via the importing process. This makes rumble work immediately after any BPM change, instead of having to wait 1 beat to start
• Improved PS/2 input key handling by making each keypress event last at least one frame
• Adjusted audio lag corrections when using the rate mod (better measure)

Graphical improvements:

• Updated text font by adding borders

• (v1.8.4) Fixed an importer bug which could cause subindexes to appear in situations where they shouldn't (e.g. deleting level-99 charts via offsets.pofs)

v1.7.*

New features:

• Menu controls
  • 
  • 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
  • 
  • 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
  • 
  • 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
  • 
  • It now uses the AutoMod/INSANE, +1 rate, and mirror steps mods
• Admin menu
  • 
  • 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

• 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

• 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
  • Added 'transmitting' animated icons. On the host side, it will show two 'sending' icons over the lights. On the client side, a 'receiving' icon at the corner
• 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
