INSTALLATION / SETUP
__________________________________________________________________________________________________________________________________________

Open GTA3.IMG File in MODELS Folder with IMGTOOL Program

hi_cutsafehoos.txd
dw_scuz_kb.dff
dts_shops_new1.txd
doontoon13.dff
downtows.col

Delete Files and Add New Files with Mods

And Then in the data/maps/downtows folder

downtows.col
downtows.ide
downtows.ipl
delete the files and add the modded files / or replace the old files with new files (if you do not want to deal with it, paste the modded downtows folder)


Additionally, ADD THE "dw_scuz_door.dff" FILE, which does not exist in the game, WITH IMGTOOL.

GTA3.IMG
GTA 3.DIR
Be careful that the files are not read-only. Otherwise, the IMGTOOL program will not run the files and the program will crash.

Likewise, the col, ide, ipl files in the data/maps/downtows folder should not be read-only.

__________________________________________________________________________________________________________________________________________________________________________

dff you want to control with the DFF WIEVER Program. Open the files and check if there are any problems in the files (the file in this mode is "doontoon13.dff" OR "dw_scuz_kb.dff", now try whichever is problematic)
Sometimes dff.files may crash and dff files may appear corrupted, 
If there are problems with the files, open the RWAnalyze program
Go to "File" at the top, click "Open" to open the existing dff. file, go to "Commands" in the "Tools" tab, something will appear called "Change File Version", go there.
Save the existing dff file as "RW 3.3", delete the old one with IMGTOOL and add it to the game.

Another Error: Make Sure You Place the Files Correctly with the Correct Name, do not try to change the name of the dff or txd file and add it as such, because the game needs to identify the original existing file.
In this case, a white texture error may occur in the textures, and the game may crash when it comes to the modded location.
If you get an error due to coll files, you can check which file mode coll with the COLL EDITOR program. file, check it (we will open the downtows.col file in this mode) 

After opening the downtows.col file

doontoon13.col
dw_scuz_door.col
dw_scuz_kb.col

Make Sure Whether The Moded Version Of These 3 Files Has Been Added To The Game Or Not. I'm Already Adding The Downtows.col File Of These 3 Files That Have Been Added To The Game Directly To The Mod.

"dw_scuz_door.col" (file is the file that is not in the normal game. If downtows.col does not have that file, add it as well. As I said above, I am sharing the directly added downtows.col file with you.

(WHEN I CHECK THE MAP WITH MAP EDITOR, IF THE PROGRAM CRASHES WHERE THERE IS A MOD, I COULD NOT FIND A SOLUTION TO IT. WHEN THE FILES ARE TOO LARGE, SOMETIMES THESE ERRORS MAY OCCUR)
