 ## Plans
 
 * ~~Decompile original game~~
 * ~~Resizable window, scaled graphics~~
 * ~~Loader for high-res sprites from CADET.DAT~~
 * ~~Cross-platform port using SDL2, SDL2_mixer, ImGui~~
-* Misc features of Full Tilt: 3 music tracks, multiball, centered textboxes, etc.
+* Full Tilt Cadet features
-* Maybe: Text translations
+* Localization support
-* Maybe: Android port
+* Maybe: Support for the other two tables - Dragon and Pirate
-* Maybe x2: support for other two tables
+* Maybe: Game data editor
-  * Table specific BL (control interactions and missions) is hardcoded, othere parts might be also patched
