Talk:ICO Format (Halloween Harry)

The palette entries here use the same palette as the HSB file does. With some corrections I was able to reproduce all 35 images in the ICO file faithfully (with the caveat that the palette I'm using has some RGB values which are close, but not exact, matches to the actual in-game values). -Duckthing

This suggests that the executable has palette(s) in it that are applied to relevant game files. Tell me, is the PCX palette used for the fullscreen graphics (That is, changing the PCX file palette changes the palette displayed) or do PCX graphics use the same palette as everything else (Which would be further evidence for the executable holding the palette.) -Endian?

No idea, because I haven't been able to decompress any of the BNK files to look at the PCX files. I read something somewhere that suggested they're LZW compressed but I haven't had a chance to really play with it. I'll probably work on it over the weekend. -Duckthing

It looks like the files can be decompressed with PKware's "explode" algorithm. The ACXTRACT program by Admiral Bob can decompress them. -- Malvineous 03:01, 4 December 2010 (GMT)

Thanks so much -- that helps enormously! I've made a lot of progress on several of the file formats (namely the map files, the tile art, and the cut-scene scripts) packed in the BNK files and will be posting articles for them once I get time to write and format them properly. Thanks again for the link! -Duckthing 19:20, 5 December 2010 (GMT)

Sounds great! Particularly about the map files :-) Hopefully you can figure out how to link them back to the graphics, as this often seems to be the trickiest part... -- Malvineous 00:40, 6 December 2010 (GMT)
