Enter a valid SpaceChem Mission-code in the textarea under 'mission code' and hit 'SEND CODE'.
The 'convert' box enables element substitution. For the special elements, enter the the atomic number or symbol of the element you want to replace. Under batch, enter 'src:dst' pairs to assign your own conversions. Example: "Ru:omega 108:H" would replace Ru with Ω and Hs (element 108) with H. Elements Θ, Ω, Σ, Δ and Australium (Av) are elements 200-204, respectively. The 'void' element (?) is 0. Any unknown elements are converted to 0.
