dimok321 96cb18d26f *fixed reversed disc image download when Custom/Original option is selected (Issue 1871)
*corrected the patch for returnTo using d2x (should be working now)
*added block ios reload of d2x. you can choose the methods in the game settings (same option as for hermes ios but it can be 1 or 2 on waninkoko ios, last option on screen) (not tested yet)
*major restructuring of patching code for game patches inside the source
