Undo unnecessary complicated memorycard memory processing and just avoid overwriting kernel memory.
-removed disc read limit
-pre-reading data when no cache is specified and the game wants to load something with the same data size, this highly reduces the time of animal crossing bootup for example
-added a proper patch for RADTimerRead, with the help of this patch games using Bink Video will play back videos properly (for example megaman collection and scaler)
-removed some unneeded code for the SI interrupt
-using a general ISO reading function which makes sure we dont seek unneeded, this increases general reading for slow HDDs
-slightly increased the sectors you can read from the HDD at once, this helps further to increase reading speed from HDD
