+      Sim65 is a 65c02 simulator and debugger for Linux/GTK systems.
+      You can load binary images or S-record files containing 65c02 code and execute it.
+      Sim65 allows you to see and alter registers and memory, set breakpoints, single step, and a few other things.
+      The program is immature: there are no peripherals, for example, but it suffices for simple simulation purposes.
