• based on r12452 (internal rev1926)
• the NDS port now has a different toolbar, more suitable for the small screen
• for better access with the touchscreen the toolbars have been moved to the bottom screen
• a fully customizable on-screen keyboard has been added (click on a text field to open it)
• a newsticker display on the lower screen has been added
• some windows have been adapted for the NDS screen (more will follow in future releases):
  
  • intro menu
  • game creation menu
  • minimap
  • build vehicle window
• when building depots and stations only one preview image is shown which you can rotate by clicking on it
• information regarding accepted cargo when building a station is displayed as icons now
• switching screens (left shoulder button L) now only switches the windows
• many windows (e.g. confirmation dialogs) are now centered on the bottom screen
• the amount of free ram (in kb) is displayed in the middle of the status bar. This is only a temporary change to help with tracking down a memory leak
• additionally you can view some memory information by pressing the B button
• always use new global pathfinder (NPF). the original TTD pathfinder crashes due to too many recursions
• fixed loading screen glitch

• random crashes when the game runs out of memory
• graphical glitches (mostly during scrolling) because the nds blitter needs to be rewritten
• minimap glitches
• trying to create maps bigger than 256x128 crashes
• the screen resolution is too small making it impossible to click some windows
