How do I install J2ME games on J2ME-Loader?

Obtain J2ME game files (JAR/JAD) legally, then open them with the app or place them in an accessible directory. J2ME-Loader will detect and allow you to configure each game with individual settings for optimal performance.

Is J2ME-Loader better than other Android J2ME emulators?

J2ME-Loader stands out for its Mascot Capsule 3D support and per-app customization, but alternatives might offer different features; compare based on specific game compatibility and user interface preferences from community feedback.

Why is my game slow in J2ME-Loader?

Slow performance is often due to filtering options; disable filtering in the app settings as recommended in the README tips. Additionally, adjust per-app settings like screen scaling to improve speed.

Does J2ME-Loader support all J2ME games?

No, while it supports most 2D and 3D games, compatibility varies. Check the project's wiki for lists of tested games and those with bugs to see if your specific title is supported.

How to fix screen flickering in J2ME-Loader?

Enable the 'Immediate processing mode' option in the game's settings. This is a direct solution from the README tips to resolve image flickering issues in certain titles.

Can I use J2ME-Loader on the latest Android versions?

Yes, it requires Android 4.0 or higher, so it should work on modern versions. However, check community forums for any reported issues with newer Android updates, as system changes might affect compatibility.
