To upload a config.txt as well you will have to do the following if the title is installed on NAND:
```
w.up("config.txt", "/vol/storage_mlc01/usr/title/00050000/YOUR_GAME_TITLE_ID/content/config.txt")
w.chmod("/vol/storage_mlc01/usr/title/00050000/YOUR_GAME_TITLE_ID/content/config.txt", 0x644)
```
and for the title being installed to USB you do the following:
```
w.up("config.txt", "/vol/storage_usb01/usr/title/00050000/YOUR_GAME_TITLE_ID/content/config.txt")
w.chmod("/vol/storage_usb01/usr/title/00050000/YOUR_GAME_TITLE_ID/content/config.txt", 0x644)

please note though that if you want to load a fw.img the name HAS to be named fw.img in whatever folder you use, nothing else will work.
