That's really quite impressive, thanks for your advice. I have Delphi 7 & 2007. So the compiler is already taken. For sound effects I'll try that Paul's recomendation (I must confess that a project to build a sound maker is on my todo list, also a sprite editor). For the graphics I'll go with the Gimp and an old tile editor made with Delphi (http://tilestudio.sourceforge.net/). For music I still didn't decide between mod, midi, mp3 or ogg.
