Lode Runner plus Doom. What a trip! Just collect the gold and run. Interesting concept, but easy and still basic level.

It involves lots of switches which let you progress, but the level design is too bare to be of great interest. Be Careful! EMBED for wordpress. Want more?

SIGIL v1. It is possible for more than one lump to have the same offset value, as well as having offsets that overlap other lump data. When a modder imports lumps into a WAD from other files, file extensions are not included. Doom's executable examines only the name field to determine whether all required entries are present at launch.

This means, for example, that the encoding of a music track may not be immediately obvious if the WAD's intended port supports multiple formats. If the first character of the name has the 0x80 flag set then it is considered to be compressed. The compressed size of the lump is not stored as the compressed stream has a terminating sequence.

It should not be assumed that the compressed data is smaller than the uncompressed size since compression is required for some lumps in the console ports. Likewise some lumps are required to be uncompressed in order to be read directly from cartridge ROM. The stream has a bit sliding window. The format of the compressed stream is a flag byte followed by 8 chunks. The size of a chunk is determined by the flag byte in least significant bit first order. If the bit is not set then it is a uncompressed byte, otherwise it is a bit offset length pair.

The first byte of the pair is the upper 8-bits of the offset. The upper 4-bits of the second byte is the lower 4-bits of the offset. The remaining 4 bits are the length to copy. The offset is from the current output position or from the end of the sliding window and may overlap. Length is incremented by 1 so it becomes some value If length is 1 then it is the end of the stream.

In order to know in advance how much information to read from the compressed lump, console versions of Doom which utilize this compression algorithm take the difference between the offset of the target lump and the next lump in the WAD directory. This avoids undefined behavior if the last lump in the directory happens to be compressed. The majority of lumps have no restrictions on where they must be located in WAD files, although there are typically some guidelines to make the file easily readable by other people.

For certain lumps, however, the location is crucial. A map in Doom is made up of several lumps, each containing specific data required to construct and execute the map. The first lump gives the internal name of the map.
