+
+ Konami JE 502/JE 503 Hyper Shot emulation
+
+ Very simple controller with two buttons. RUN is connected to
+ both right and down, and JUMP is connected to TL. Symmetrical
+ case allows use with either button to the left.
+
+ Known versions:
+ * JE 502 original Japanese version, metal case
+ * JE 503 cost-reduced Japanese version, plastic case
+ * JE 503-X02 cost-reduced export version, plastic case
