+
+Yes, you always wanted to have an arcade board at home. First you couldn't get it because your parents somehow did not understand you. Then you grow up and your wife doesn't understand you either. Don't worry, JT cores are here to the rescue.
+
+I hope you will have as much fun with this project as I had while working on it!
+
+# Supported Systems
+
+This FPGA core is compatible with the following arcade PCBs:
+
+- Sunset Riders
+- TMNT Turtles in Time
+- X-Men (not on MiST devices)
+
+Due to limitations in the internal RAM memory of small FPGA devices, X-Men will not run on MiST FPGAs.
+
+# Game Configuration
+
+This game does not use DIP switches but a small EEPROM to save the configuration. Access to the configuration by pressing F2 on your keyboard or pressing button 1 and coin in the Analogue Pocket. Follow the game menu to alter the configuration from that point on.
