I'm pretty sure rev 20 should work as well, but try 17 just to see.cIOS249-v17.wad use wad manager or multi mod manager to install.
actually try this first:cIOS249-v20.wad
the rev 2o you have may be bsae 56 instead of 38
Did you happen to notice this on the guide here??? I have not read the guide in a while, perhaps you should go back and read it too.GX doesn't have full support for rev20 Waninkoko cIOS that came after r938)
Wait a few days... they are almost ready to release a final new rev. I have been reading about it on there Google code site
Added Revision 1031 download link to the first post
i checked neogamma r9b47(i want usb loader gx bc it's better, or so i hear), and saw that i had base 57... on slot 249. I will be using WBFS. but since i hav rev 20, should i downgrade???? Is that Safe?? i tried version 938 of the USB LOader GX and it came to the screen that says please plug in ur usb device or whatever and that is normal because i didn't plug it in i just wanted to c if it would work. Is that goign to work? and btw when that screen came up, it said IOS 249 or IOS 222 or something like that. Which one should i choose?btw i read the thread but i kinda need to ask questions, i ask a lot of questions. I try to understand things better this way so i can help some1 in the future.
I recommend using rev 17 because so you won't get confused with the bases and all that stuff. It is saw to downgrade from cios version.
Yes it is safe. use a wad manager and to install and it overwrites it. you choose 249 because thats the one your using.
