nmania

Open source Vertical Scrolling Rhythm Game for J2ME. Compatible with osu!mania beatmaps and intented to be it's clone. More gameplay modes and support of other games' beatmaps may come in future.

Project status

The project is not abandoned. Feedback and bug reports are accepted. All opened issues are planned to work on in nearest years. You can ask me for help via telegram or osu! chat.

System requirements

Minimal

• JVM/KVM on your device with CLDC 1.1
• MIDP 2.0/2.1 support
• JSR-75 (FC API), JSR-135 (MMAPI)
• Support of MPEG audio playback (it works better when audio is HWAed)
• At least 2 mb of RAM (this won't be enough, 8-12 is okay)
• Physical keyboard
• (or) Ability to connect one
• (or) Multitouch touchscreen
• Ability to handle at least 2 simultaneously held buttons (4+ will be okay) / at least 2 pointers (on touchscreen).
• Keyboard is always better than touchscreen, trust me. At least on nokia devices.
• Enough perfomance. In case of Symbian, ~450mhz CPU may be okay (f.e., OMAP 2430/31), but it depends on JVM implementation and CPU capatibilities. 9.3 devices work the best.

  Recommended devices

  Symbian 9.3 device with QWERTY keyboard is recommended (E5, E72). Symbian ^3 devices like E6, E7, N8 have performance issues.

  Emulators

• J2ME Loader has major problems with native UI, but playable. Use OTG or BT keyboard. 640x360 is recommended. Your working folder is likely /storage/emulated/0/Data/Sounds/nmania/.
• PhoneME is partially playable, has major problems with input/gameplay/music synchronization and files.
• KEmulator is not compatible due to broken multimedia API.
• KEmulator nnmod is partially playable. Skin settings are not functional, multihold is not propertly supported. Use file:///root/ as your folder, or else it won't work.

How to play

Go to osu!direct or it's mirror and download maps that you want to play (or copy them from stable's Songs folder). Extract your maps to C:/Data/Sounds/nmania/ (if there is no such path, create folders manually) like stable does - one nested folder for each mapset.

There is no guarantee that your beatmap will work as it is! You may need to reencode the music to MP3, rename weird files, etc. osu!, osu!taiko and osu!catch beatmaps are not supported! You need osu!mania-first beatmaps (for "mode" 3).

If you have a standalone nmania beatmap, you need to compose a BMS yourself. Create a nested folder, place the beatmap file here. Find the music track and background image for it, put them in the same folder with the beatmap (keep eye on files' names, rename them if needed).

Launch the game and play. You may want to adjust scroll speed, dim and sound effects in settings, adjust look of the game in skinning, or read this manual again in info.

If the game is too laggy even with flat skinning and without sounds, there is likely something wrong with your device, WORKSFORME.

Don't try to play with screen recording / streaming enabled or with BT headphones.

Rich skinning structure

It's written inside the game. Please read "info". Ask in issues if you didn't understand. You can also explore a template. Currently we don't provide "osu!classic", "triangles" or "argon" skin out-of-the-box. Remake them for this game yourself if you need. OSK skins are not supported. Remake them if you need.

Language setting

To apply a localization, pack your files into jar under names CATEGORY_LANG.txt as english files named. In game settings, enter the LANG postfix. Refer to source code if it doesn't work.

Flush rate troubles

Default HUD rendering requires 3 flushes in a game frame. This can limit FPS to 20 or even 16 on some devices. Try to enable fullscreen flush. Now there will be 1 flush in 1 frame, but yeah, the whole screen. Still bad? Disable HUD at all (draw counters) (don't forget to disable fullscreen flush too!). Now you will have 1 partial flush in 1 frame. This should be enough. This won't help belle devices.

Ready binaries

Stable

Look in releases. Use "obf" version if you don't know differences between them. Use "lite_obf" version for low-end devices like S40.

Latest

On commit panel find green checkmark (if you see red cross, look in commit history for latest working), click it. Go to "summary" tab. Scroll down. Here are the latest builds.

Manual build

Linux

Run build.sh. Note that it modifies source code! Do not forget to reset all changes using git after building! Look for files in ./jar/ folder.

Windows

We don't have build automatization for Windows. Install 1.6.0 jdk and latest WTK or your device's SDK. Look for futher instructions in it's documentation (you want to package a MIDlet suite).

Mac OS / exotic *nix

You will have to deal with it by your own. Wine and J2ME toolkits for Windows may help you.

IDE

This game was created using Eclipse IDE for Java with Mobile Tools for Java (MTJ) plugin for it. You also need J2SE 1.5 and an SDK for your device. Set up them to work together and create a JAR package from Application Descriptor screen.

Other IDEs

Netbeans and old IntelliJ work too. You will have to deal with them by your own.
