if i download the game from here will it include all the updates or will i have to manually update the game myself by downloading the packs
Assuming the download includes SP7 like it says it does, my guess is that you would have everything already installed and good to go. There are two patches that were done since SP7, but those fixes are as follows:
1. In general sex, no images shown for Female PC using dildo Adult Female NPC.
Also fixes some oddities in the outcome of dildo sex recieved by the PC (will be in a ZIP file if I can attach that, when you open it extract to your base folder and it will update everything it needs for the fix assuming you are using NormalSchool)
2. Using vaginal double dildo not resulting in orgasm for the PC. (that'd be the other non-zip file, install here:
Schools\NormalSchool\Events\FunctionLibrary\GetPhysical\SetEffectSubs)
That should be everything for the base game, though I will mention that I can't help much with most mods. I've dabbled in making Lexville and the Preg mod work together, however that was a pain to set up and I haven't played Lexville enough to seriously know where stuff may or may not break. Just know that unless the mod says you can, don't expect to just copy a mod into the NormalSchool (default) folder as Lexville itself has its own folder structure using ModSchool. In general if you want to mess with mods, I recommend installing a second copy of the game/folder structure so that should you break anything you can at least have an "uncorrupted" set of files.
*EDIT:
Sorry i not know. In what place we put this?
Once you're in the game, in the very lower right you'll see a "Debug" button. Click it and a window will open up. Near the bottom of that window you should see the text "Console Command", and underneath that you'll see a white bar. You can type in that bar (took me a while to realize as well). From there, just start typing letters to see a list of all the commands available, but generally speaking you want to stick to stuff that starts with 'A' because that's the 'Add' command.
Most commands will be self explanatory, though I will stress that anything that has multiple words will require an underscore, including items and names, and you have to capitalize every word. (i.e. "energy drink" has to be "Energy_Drink", so if you wanted to give yourself an energy drink you would type "add item Energy_Drink to Richard_Johnson", or whatever your character name is as that name is the default male name).
On a similar note, anything that is a "unique" item I have had 0 success debugging this way, so you cannot cheat the teddy bears as far as I can tell (I think because they already have an underscore so their names are weird along with the uniqueness). Also on a final note, if for whatever reason you want to debug time to skip ahead, keep in mind that your character is basically standing there awake the whole time doing nothing, meaning if you jumped ahead a week then as soon as you take a step your character will pass out from exhaustion.
