BMS player for PSP created by users from 2ch. It supports BMS and BME files and also allows you to change skins.

Installation

Extract the folder to the Memory Stick (ms0:/PSP/GAME/).

Also included is a memory fix EBOOT.PBP (for PSP-2000/3000), to use it just replace with the one in the folder.

Folder structure: 

JzBMSPlayer\
  |-BMS\
  |-WAVE\
  |-SKIN\
  | |-SELECT.FNT
  | |-DEFAULT.zip
  |-BMS.INI
  |-EBOOT.PBP
  |-README.TXT
  |-SYSTEM.FNT

BMS.INI

Default BMS.INI format: 

VER=version_number
BMSPATH=Root path of the memory stick (can be modified)
SKINPATH=Absolute path to the SKIN/ directory when JzBMSPlayer was first launched (can be modified)
WAVEPATH=Absolute path to the WAVE/ directory when JzBMSPlayer was first launched (can be modified)

(VER=20000 is the version number for BMS.IN. Do not modify this value).

BMSPATH:

  • Specifies the absolute path to the BMS folder. When scanning BMS files on the selection screen (Triangle), the application will search within the folder defined by BMSPATH. If left at the default setting, it will search through all files on the Memory Stick each time (less efficient). Set this to the absolute path where your BMS files are stored.
  • Example: BMSPATH=ms0:/BMS/
  • (Please make sure the absolute path "ms0:/PSP/GAME/BMS/-----/-----/-----/*.BMS" is less than 512 characters.)

SKINPATH:

  • Specifies the absolute path to the SKIN folder.

WAVEPATH:

  • Specifies the absolute path to the WAVE folder. This path is used if the BMS file does not contain the required WAV files. Place general-purpose WAV files used by various BMS in the WAVE folder.
  • These WAV files can placed in a single ZIP file, but if you do so, you need to append a ? (question mark) to the end of the file name and directly specify it in WAVEPATH.
  • Example: WAVEPATH=ms0:/PSP/GAME/JzBMSPlayer/WAVE/musicbox.zip?

Example (PSP-1000): 

VER=20000
BMSPATH=ms0:/
SKINPATH=ms0:/PSP/GAME/JzBMSPlayer/SKIN/
WAVEPATH=ms0:/PSP/GAME/JzBMSPlayer/WAVE/

Example (PSP-2000 and PSP-3000): 

VER=20000
BMSPATH="ms0:/"
SKINPATH="ms0:/PSP/GAME/JzBMSPlayer/SKIN/"
WAVEPATH="ms0:/PSP/GAME/JzBMSPlayer/WAVE/"

Other values in BMS.INI can be changed within JzBMSPlayer. Do not modify the VER line or other parts, as it may cause the application to malfunction or fail to start.

Important: When compressing WAV files into a ZIP archive, do not compress with the folders (it will not be able to locate the files).

Adding songs

Place the BMS files in a folder alongside EBOOT.PBP in the same directory (example: ms0:/PSP/GAME/JzBMSPlayer/BMS).

It also supports zipped BMS files.

After adding the songs, go to the song selection screen and press Triangle to scan for new files.

Adding skins

Place the skin files, in ZIP format, into the SKIN folder.

Open the skin selection screen and press Triangle to scan for new skins. The newly added skins will appear in the list.

File formats

  • WAV - Supported by default.
  • MP3 - Only supported for streaming playback. Use MP3 files as distributed; converting WAV to MP3 may introduce discrepancies, so it's not advised for BMS files not originally designed with this format.
  • OGG - Supported for both streaming playback and key sounds. If you compress your own files, use OGG. Key sounds are decoded and stored in 8-bit but will be stored as 16-bit if tagged as COMMENT=16BIT, which uses twice the memory.

To play BMS files that exceed memory limits, try lowering the WAV audio quality or converting images to half-size BGA.

Please note that streaming playback is not supported for compressed ZIP files containing WAV, MP3, or OGG files. To enable streaming playback, keep the files uncompressed in the folder.

User guide

Starting the program

Power on your PSP and select JzBMSPlayer from the GAME menu to launch it.

After launching, choose a song that you've added. The program will load the BMS and WAV files, and the performance will begin.

Menu screen

Note: Using the Home button to exit will not save settings such as skin preferences. Always exit using the Exit option in the menu.

Name Option Action
Skin auto/5/7/14/4/8/other Choose the skin you want to use.
Rank auto/v-hard/hard/normal/easy/v-easy Change the difficulty rank.
Speed 0.50/0.75/1.00/1.25/1.50/---/3.00 Adjust the note scrolling speed.
Tempo 1.00/---/2.00/max1.5/max2.0 Change the tempo (BPM).
Screen normal/hidden/sudden Choose between Hidden or Sudden modes.
Survival on/off Toggle Survival mode on or off.
AutoPlay on/off/sc Toggle AutoPlay on or off.
KEYASSIGN Change key assignments.
SKIN Change the skin used.
LVlimit on/off Toggle sound distortion prevention on or off.
Priority Main/Sound Change processing priority.
OverCLK off/loader/player/both Change overclocking settings.
Filer Access a high-function file manager.
Exit Always use this Exit option to end the program.

Rank:

  • Allows you to change the difficulty rank specific to the BMS.

Tempo:

  • max1.5: The tempo increases slightly as the Groove Gauge (0%-100%) gets higher (up to 1.5x).
  • max2.0: The tempo increases slightly as the Groove Gauge gets higher (up to 2.0x).

Survival:

  • When the Groove Gauge reaches 0%, the performance will end immediately, and you'll be taken to the results screen.
  • This is intended for advanced players.

AutoPlay:

  • sc: Auto Scratch (only effective for 5/7/14 KEY modes).

Priority:

  • Main: Prioritizes rendering (may introduce minor noise with complex harmony).
  • Sound: Prioritizes sound quality (may cause scrolling lag).

OverCLK:

  • off: No overclocking (233 MHz).
  • loader: Overclock only during BMS loading (333 MHz).
  • player: Overclock only during playback (333 MHz).
  • both: Overclock during both BMS loading and playback (333 MHz).

Warning: Overclocking can reduce loading times and prevent performance drops during playback but may drain the battery faster. If using mp3 for BGM, overclocking will be enforced during playback. Use overclocking at your own risk.

Loading screen

Name Action
continue Continue loading.
skip Skip the loading process.
cancel Cancel loading and return to the song selection screen.

During loading, the filename and remaining memory are displayed. If the BMS file specifies an image with #STAGEFILE, it will be shown during loading. Example: #STAGEFILE load.bmp

If the BMS file does not include a #STAGEFILE entry, no background image will be displayed during loading. Pressing the X button during loading will abort the process. Pressing the Select button while aborting will display the debug log.

Performance screen

  • Press Start during playback will stop the performance and go to the results screen.
  • Press Select during autoplay will turn off autoplay.
  • If the selected BMS does not have image files, a visualizer will be displayed.
  • You can switch the spectrum analyzer using the up and down analog keys (7 patterns available).
  • You can switch the feedback mode using the left and right analog keys (12 patterns available). Each feedback pattern includes two versions: BPM reflecting and BPM ignoring.
  • The higher the Groove Gauge (0%-100%), the more elaborate the visual effects.

Screenshot

The screenshot function is available only in the song selection screen, performance screen, and results screen.

Create a folder named SS for screenshots as shown below: 

JzBMSPlayer\
  |-skin\
  | |-SELECT.FNT
  | |-DEFAULT.zip
  |-SS\   (screenshot location)
  |-BMS.INI
  |-EBOOT.PBP
  |-README.TXT
  |-SYSTEM.FNT

While in the song selection screen, performance screen, or results screen, press L+R+Select simultaneously. This will save a screenshot in the SS folder in PNG format.

If pressing L or R alone causes a menu to appear, hold down L or R, press the X button to close the menu, and then press Select to take the screenshot.

EX score formula

Key Multiplier: 90 × (Total Keys - Keys Assigned) / (Total Keys - 1) + 10

EX Score: (COOL (4 points) + GREAT (2 points) + GOOD (1 point)) × Combo Count × Key Multiplier / 100

Round down the result. If it is less than 1 point, it is set to 1 point.

Note: If you use all available keys, the score for each key assignment is reduced to 10% of the score for a single key assignment.

Tips for achieving high scores:

  • Focus on maintaining a high combo count.
  • In difficult sections, don’t push yourself too hard. Use multiple key assignments to handle tough parts and keep your combo going.

    • OGG: Supports streaming playback and key sounds.
      • If you compress your own files, use OGG.
      • Key sounds are decoded and kept in 8-bit format; if the tag comment specifies "16BIT" (COMMENT=16BIT), it will be stored as 16-bit (uses twice as much memory).
  • Changed the streaming playback detection to use the first #WAV found that is not reused in the BMS, based on the #WAV definition order, if #WAV01 is over 5MB.
  • Added three more level meters.
  • Changed judgment to be time-based.
  • Changed early press "Poor" to no judgment.
