Open source piano-like rhythm game for J2ME, compatible with osu!mania beatmaps.

• JVM/KVM on your device with CLDC 1.1
• MIDP 2.0 support
• JSR-75 (FC API), JSR-135 (MMAPI)
• Support of MPEG audio playback
• At least 2 mb of RAM (likely this won't be enough, 8-12 is okay)
• Physical keyboard / ability to connect one
• Ability to handle at least 2 simultaneously held buttons (4+ will be okay)
• Enough perfomance. In case of Symbian, ~450mhz CPU is okay (f.e., OMAP 2430/31), but it depends on JVM implementation and CPU capatibilities.

9.3 or ^3 Symbian device with keyboard is recommended (E5, E6, E7, E72).

• 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.

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. 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.

Find a SDK for your device, install it. Look for futher instructions in it's documentation (you want to package a MIDlet suite).

If you want an IDE, i can recommend 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.
