@@ -97,6 +97,32 @@ Stephh's notes (based on the games Z80 code and some tests) :
   - Same ingame bug as in 'mirax' when you reach level 100 (of course, it will display
     "LUXORI UNIT" instead of "MIRAX CITY" on "presentation" screen).
 
+
+Roberto Fresca notes about set 'miraxb'
+
+  - The game starts without a self test.
+
+  Stages:
+
+  stages 01 to 10 : "MIRAX"
+  stages 11 to 20 : "RUTHIN"
+  stages 21 to 30 : "GORGAN"
+  stages 31 to 40 : "PEMBAY"
+  stages 41 to 50 : "URMIA"
+  stages 51 to 60 : "VENLO"
+  stages 61 to 70 : "OHRE"
+  stages 71 to 80 : "DESBOM"
+  stages 81 to 90 : "XELUN"
+  stages 91 to 99 : "MURBO"
+
+  After the stage 99, the game jumps to stage 1 (take as 100), where you reach the city.
+  even displaying the wrong text. Cities appear at stage 1, 11, 21, etc...
+  Once you reach again the stage 99, you'll get the stage 1 again,
+  but the city will displace to the stage 2, 12, 22, etc... Always with wrong text on screen.
+
+  Indeed it's a bug of the game.
