Open Transport Tycoon is finally on the DS (check out the PSP release here), giving us a nice dose of economic simulator love for Nintendo's handheld.

According to Open Transport Tycoon Deluxe developer dominik81, the game is now running smoothly for the DS, and can load 128x256-sized maps. Here's the changelog for the DS release of Open Transport Tycoon:

Other notable changes are:

• based on r11844
• maps up to 256x128 running (but saving only works for 64x64 right now)
• saving and loading works
• in openttd.cfg you can define a path where your data resides
• loading time greatly reduced from 45 seconds to 15 seconds
• rewritten the blitter to free 96KB of main RAM

Some serious bugs still remain:

• pathfinder crashes
• open road station gui, then click on road depot icon -> crash
• station gui crashes / not displayed correctly
