How to install everything else
1- open up TXD workshop
2- open up gta3.img
3- type in the either wmydrug.dff, wmydrug.txd, paracx.txd, gun_para.dff, gun_para.txd.
4- replace them with the ones in the download.
-You may only replace 1 at a time
-The .dff is the model and the .txd is the skin, so it would be unwise to only use the dff, as it would be unwise to only use the txd for a given name.
-You have 2 options for the wmydrug.txd. They are both displayed in the screenshots
