-		Crash Team Racing will refuse to boot if psxM[2] and psx[3] are not set to 0.
-		Fade to Black can crash upon memory card access if byte 5 is set to the wrong value.
+		Here are some examples of games not working with this fix in place :
+		R-type won't get past the Irem logo if not implemented.
+		Crash Team Racing will softlock after the Sony logo.
