DOOM Retro v2.9.3

• The following changes have been made to the support for John Romero’s megawad SIGIL:
  • The SKY5_ZD lump is now used instead of the SKY5 lump to render the sky.
  • The +jump action is no longer disabled if SIGIL.wad is loaded automatically.
  • A bug has been fixed whereby the SIGILINT lump was being displayed in the intermission’s background for episodes 1 to 4.
