Basically,
1.Copy the 'cxmb' folder to the root
2.Add the line
ms0:/cxmb/cxmb.prx 1
to vsh.txt
3.Go to ms0:/PSP/THEME
4.Place all of your .CTF files in there
5.Copy the CTF_Convertor.exe file into the THEME folder aswell (saves me time)
6.Run CTF_Convertor so it makes all your CTF's compatible with GEN/CFWe
7.Exit USB connection
8.Restart XMB by entering a homebrew/game (musGo to t be in CFWe/GEN)
9.Go to theme settings and change the theme to your custom theme
10. If you can't see custom themes and only .PTF files...
11. Go to recovery menu/plugins or settings menu/pugins to see if cxmb.prx is enabled
12. And check that you entered the right line into vsh.txt
12. Make sure that you create a cxmb folder and don't just add cxmb.prx into seplugins
