decomp-it-up-Zero v0.2.5

Pump It Up: Zero reconstruction for Windows (64-bit and 32-bit), version 0.2.5.

Downloads:

• decomp-it-up-Zero-win64.zip (64-bit): Pumpy.exe, SDL2.dll, z.dll (zlib), vcruntime140.dll.
• decomp-it-up-Zero-win32.zip (32-bit): a single Pumpy.exe with everything linked in, no DLLs needed.

Video (libmpeg2) is linked into the executable in both.

How to use: extract the zip into your own Pump It Up Zero data folder (next to AUDIO/, BGA/, SCRIPT/, TITLE/, WAVE/ and STEP.DAT) and run Pumpy.exe. Game assets are not included.

New in 0.2.5:

• Easy Station: picking EASY on the station screen now opens its own song select instead of falling back to ARCADE.
  • 19 songs with levels 1 to 3, as in the original, played with the practice steps.
  • Up-left changes the speed (X1, X2, X3), up-right changes the skin, down-left / down-right change the song, center sets ready and then starts.
• Scene masks: some screen layers are stencil masks that clip the next layer instead of being drawn. They were drawn as plain sprites, which left opaque squares around the side arrows of the Easy Station select.

Re-uploaded on 2026-10-11: the first zip of this version crashed on startup (a build problem, not a code change). If you downloaded it before this note appeared, download it again; the hashes below are for the fixed file.

Easy Station, not yet: the tutorial song, the intro video, and the station's own Next Stage, Game Over, Dance Grade and graduation screens. After a song the flow continues through the ARCADE screens.

Known issues: the Accelerate (AC) and Decelerate (DC) modifiers still have no effect, and there is a pause of about one second when entering the ARCADE song select.

Antivirus note: some engines flag new, unsigned executables with generic or machine-learning heuristics (for example Trojan:Win32/Wacatac.C!ml). Pumpy.exe is built with MSVC directly from the source in this repository, with no packer or obfuscation, and it has no network code. If Windows Defender blocks it, open Windows Security → Protection history and choose "Allow on device", or build it yourself (see README).
