Hello there.
I ported Convey SDL to the Dreamcast. Hooray! It's now the 3rd dreamcast port of this game.
My port doesn't even suppport the joypad, you can only use the keyboard. Blame me! ;-) I'll release a fixed version
soon. The next update should have some new levels, too.
I used SDL and KallistiOS from DC Dev ISO R4 to compile it. Please also note that this game was only tested on emulators (Makaron and nullDC), though it should work on a real Dreamcast as well.
You can find burning instructions on sites like dcemulation.org or dreamcast-scene.com.
