+  * Much improved RIOT timer emulation never before seen in any emulator.
+    Special thanks to DirtyHairy for the implementation, and alex_79 for

   * Fixed bug with SaveKey and AtariVox not properly closing their memory
     files before starting another instance of the same ROM, when the ROM
     was opened in the ROM launcher.
