I did not include definitions because this is stuff that won't be added. It's just something to get work started on the real version.
However, after adding this to highres\textures, you would have to add following lines to textures.def:
texture 1298 { pal 0 { file "highres/textures/1289.png" } }
texture 1299 { pal 0 { file "highres/textures/1298.png" } }
texture 1300 { pal 0 { file "highres/textures/1300.png" } }
texture 1301 { pal 0 { file "highres/textures/1301.png" } }
texture 1302 { pal 0 { file "highres/textures/1302.png" } }
texture 1303 { pal 0 { file "highres/textures/1303.png" } }
texture 1304 { pal 0 { file "highres/textures/1304.png" } }
texture 1305 { pal 0 { file "highres/textures/1305.png" } }
And I did get your PM. To be frank I would rather wait for someone who can do this the real way. I appreciate the effort, but XXX contents has low priority right now, anyway.
