How to change what items the game's merchants sell

The codes of the items (when they are inside an inventory) can be found here.

1 - You need to find the merchants' stocks. For this, open the files above and simply search
the items codes + 00.
For example, if you want to find the Typhoon ammos in the file s_scn_det_limbclinic_det01_det_city_limb_clinic.drm ,
Search 335F00 (33 5F is the ID of the item "Typhoon ammo").
Why I add 00 to the code when I search them in the files is because it is easier to find them as they can exist some codes which contain 335F
in the file. But by searching the items codes + 00, I usually always find directly the merchants stocks.

Inside the merchants stocks, the Typhoon ammo's code will look like this :
33 5F 00 00 00 00 4F 02 00 00 00 00 00.

In this code, 33 5F 00 00 is the Typhoon's ammo ID and 00 00, 4F 02 and 00 00 which follows it are values which you can find inside the Typhoon's ammo paragraphe in the file pickup_database.drm (NB: Please note that the Typhoon is calle Claymore in the game's files).

Basically, items like the ammos have only 1 value which correspond to how the item looks in the game's world. But others items have 2 and some items even have 3 values. They corresponds to how looks the item when it is used by the non-playable characters.

2 - So, if for example, you want to make the Limb clinic merchant Andrea Mantegna to sell, Pro Energy Jars instead of Typhoon ammos when you enter the Limb Clinic for the second time during Detroit's first visit, then you need to replace the code ID 33 5F of the Typhoon ammo by the Pro Energy Jar's ID code which is 1B 4D.
But you also need to replace 4F 02 by the code found in the Pro Energy Jar's paragraphe in the file "pickup_database.drm", which is B1 01.

So basically to replace the Typhoon ammo item by the Pro Energy Jar's item in Andrea Mantegna' stock, you will replace:
33 5F 00 00 00 00 4F 02 00 00 00 00 00 by 1B 4D 00 00 00 00 B1 01 00 00 00 00.

Then, of course, when your modification is done, you will have to save the file s_scn_det_limbclinic_det01_det_city_limb_clinic.drm .

That's how you need to proceed to replace 1 item in the merchants' stocks.
