Q : Wiigators next loader from what I have read will no longer need patched games.If he doesn't include patched games support is their a way that after dumping a patched disc the process can be reversed?
A : He said he may release 2 different loaders - the main one will play normal ISO's burnt but will not support patched games - he may release a version that will do patched games after that. No games cannot be unpatched once they are patched - you have effectively removed data and it cannot be replaced.
