- Deframed v. 1.0
- By Chris Gillespie
- gilles2@hubcap.clemson.edu
-
- Deframed v. 1.0 is a very crude utility to extract the frame table from
- the registered version 1.2 of DOOM.EXE. Patch files can be created in text
- or binary format, edited and written back to DOOM.EXE. Deframed must reside
- in the directory with DOOM.EXE.
-
- Disclaimer: The author is not responsible for any damage this software
- causes to the DOOM.EXE file or any other software, files, or hardware.

-
- Text Patch File Format
- ----------------------
-
- The first thing in a text patch file is a .FORVERSION line, indicating
- what version of DOOM the patch file is meant to be used with. Only DOOM
- version 1.2 is supported.
-
- Following the version number are the entries from the frame table.
- The first line specifying an entry has a $ symbol in the first column,
- followed by the entry number (0-511). On a new line after the entry
- are seven unsigned 4-byte integers. The meaning of these integers is
- explained in Matt Fell's Doom Specs. As a side note, the fourth integer
- is actually two 2-byte integers, but I was too lazy to split it apart :-).
-
- Text files do not have to contain the ENTIRE frame table. It may only
- contain a few entries and the entry # next the $ symbol will be used as
- an index into the frame table.
-
-
- Binary Patch File Format
- ------------------------
-
- Deframed can also produce binary patch files. The first four bytes of
- a binary patch file contain the float value for the version of DOOM the
- patch file is for and the remaining bytes contain the raw frame table
- data extracted from DOOM.EXE.
-
-
-
- Usage
- -----
-
- When using deframed, the names of text file patches must have the
- extension, .FRT, and the names of binary file patches muse have the
- extension, .FRB. If no file extension are specified, these extensions
- are added automatically based on the option being used (it is assumed
- that binary files have .FRB for an extension and text files use .FRT).
-
- THE EXTENSION NAME IS THE ONLY ERROR CHECKING DONE TO VERIFY WHETHER A
- PATCH FILE IS BINARY OR TEXT.
-
-
-
- Example Uses:
-
- deframed -cb binpatch txtpatch
-
- Converts a binary patch file named BINPATCH.FRB to a text patch file
- named TXTPATCH.FRT
-
-
- deframed -ct txtpatch binpatch
-
- Converts a text patch file named TXTPATCH.FRT to a binary patch file
- named BINPATCH.FRT.
-
- Note: If the text file is not a complete list of frame table entries,
- it is combined with the frame table in DOOM.EXE for conversion.
-
-
- deframed -e txtpatch 18 31
-
- Extracts entries 18 through 31 in the frame table of DOOM.EXE and
- APPENDS them to a text patch file called TXTPATCH.FRT. The -e option
- only works for text patch files. Valid entry ranges for DOOM 1.2
- are 0 through 511.
-
-
- deframed -pb binpatch
-
- Patches DOOM.EXE with the binary patch file named BINPATCH.FRB.
-
-
- deframed -pt txtpatch
-
- Patches DOOM.EXE with the text patch file named TXTPATCH.FRT.
-
-
- deframed -rb binpatch
-
- Retrieves a binary patch file named BINPATCH.FRB from DOOM.EXE.
-
-
- deframed -rt txtpatch
-
- Retrieves a complete text patch file named TXTPATCH.FRT from DOOM.EXE.
-
-
- deframed -rt txtpatch -con
-
- The -con option creates text patch files in a more condensed format,
- uliminating some of the extra spacing.
-
- NOTE: DEFRAMED does not protect against overwrites.
-
-
- I do not plan to release future versions; I'm hoping Greg Lewis's DEHACKED
- will support frame-table editing in the future :-).
