Inside the zip file you gonna find two folders and a tckl file which is needed to install the mod using TKMM. The two folders contains the manual installation folder called ' DAR 1.8 - BETA 2.4' and the 'Random Enemies Everywhere' folder which contains files and instruction on how to manually enable 'Random Enemies Everywhere' option.
If you want to install the mod using TKMM, you need to manually copy the folder 'cheats' located inside the folder 'DAR 1.8 - BETA 2.4', in your TKMM merged folder so that this folder in the end will contain the folders 'cheats' and the one generated by TKMM called 'romfs'. This will basically add 'No drops limits' so it will prevent items and enemies disappear when they are too many.
I personally recommend to install the mod using TKMM.
If you want to install the mod manually you won't have access to the install options, except for the 'Random Enemies Everywhere' which need some manual work to be enabled. You'll find the instructions inside the folder 'Random Enemies Everywhere'.
If you want to enable Random Spawning Everywhere, you need to manually copy the 6 files in this folder, inside the folder:
