+// It is a Work in Progress
+// Save Ram is broken and the game will not load with save ram written through this mapper
+// This is also true on punes
+// The game also requires 1 screen mirroring modes that other 195 games dont
+// Although the game runs correctly with 195 CHR mapping, other aspects do not work
+// More research is needed
