The file content inside:
Data inside jfl's:
00_00.jfl - 12_03.jfl - picture ,inside .jfl files, but with other format !
99_00.jfl - 99_03.jfl - various pictures
99_04.jfl - JSlog.txt ? Can not be correctly extracted using current version of GameExtractor, because it says that size is 0 ???? GameExtractor has a mayor bug!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Front.jfl - .ifc files with in-game texts, positions etc.
Inter.jfl - pictures, vehicle texts with their prices and some factor?
for the extension .ifc and .txt:
just plain text files,
for the extension .bmp:
.BMP are bitmaps (looks like this, because of the header and file reference), but somehow using a compression very similar to RLE? The exact encription is not known yet. Sequences of three identical bytes are sometime written as two, sometimes not?
The .BMP header (following specification), is stripped of reserved bytes and shrunk somehow.
Description of .ifc file contents:
ifc is a script. It defines the GUI, meaning the properties of certain
buttons and texts shown. Lines marked with ; contain comments. The script seems to be
processed by game from first line to the last, so a ceratin creation order is achived.
The format is partially explained here. The
convention is:
- the values in [] brackets mean that there shese should be replaced with some text/number.
- the values in () mean this are the only possible values. Only one of them may be choosed.
- the values in brackets marked with questionmarks are not (fully) understood yet.
- some values marked as name or text? and appearing inside the scripts with underscores may
be the names of components...
This is the meaning of some values:
XPostion= [number]
x coordinate
Yposition= [number]
x coordinate
Breite= [number]
Width
Hohe= [number]
Height
Hintergrund= [bitmap name]
Background image used.
ScrollButton= [coordinate 1],[coordinate 2],[coordinate 3],[coordinate 4],[bitmap],[?],[name or text?]
ScrollButton
DialogTextButton= [coordinate 1],[coordinate 2],[coordinate 3],[coordinate 4],[text?],[?],[text?],[name or text?]
DialogTextButton - the theree texts at the end seems to equal.
TextField= [coordinate 1],[coordinate 2],[coordinate 3],[coordinate 4],[number?],[number?],[?],[name or text?]
TextField
CheckButton= [coordinate 1],[coordinate 2],[coordinate 3],[coordinate 4],[text],[filename],[?],[name or text?]
CheckButton
ListBox= [coordinate 1],[coordinate 2],[coordinate 3],[coordinate 4],[number?],[name or text?]
ListBox
EditField= [coordinate 1],[coordinate 2],[coordinate 3],[coordinate 4],[number?],[name or text?]
EditField
Button= [coordinate 1],[coordinate 2],[coordinate 3],[coordinate 4],[text],[filename],[?],[name or text?]
Button
PushButton= [coordinate 1],[coordinate 2],[coordinate 3],[coordinate 4],[text],[filename],[?],[name or text?]
PushButton
DialogButton= [coordinate 1],[coordinate 2],[coordinate 3],[coordinate 4],[filename],[?],[name or text?]
DialogButton
Popup=(1,?)
Used only in certain .ifc files, beginning with popup_
Description of .txt contents:
In the file test.txt there is a description of some values in German. The other ones, with filename prefix vehicle_ contain vehicle texts with their prices and some factor?
Description of .jfl inside .jfl contents:
Some binary format, with different stucture! Has large amount of identical bytes. These define, according to their names, some extra properties for industries, bridges,
buildings, streets, riverbanks.
Game Extractor bug !!!!!!!!!:
Game Extractor has some troubles decompressing some of this files ???? They are extractred as files with the length 0. Particullary, none of .jfl files inside .jfl's are correctly decompressed !
