hi everybody,
Is there a simulator similar to Eask68k with a graphical window available to the programmer for the 6502? Preferably a desktop application.

I'm sorry if this question seems silly, but there's quite a few 6502 simulators that I don't know which one(s) have something like what I'm looking for.

Welcome! Have a look at http://6502.org/tools/emu/ - I'm not sure there's anything which quite fits the bill. A couple of the in-browser tools offer a GUI, but I'm not sure about applications. I think Kowalski's simulator lacks a model of video memory (I'm assuming that's what you're after.)

It sounds as if you want a simulator that simulates a computer system capable of graphics. There are apple ][ and Commodore Simulators that provide color graphics. The apple used a direct memory map with some soft switches to control modes. Commodore 64's use the 6570/6571 display controller. Beyond that, many Simulators only simulate the CPU operation, not that of an entire system. The Kowalski Simulator is such a simulator. It does have some simple terminal IO (text only) to support console IO. In order to provide a color graphics display, you would have to first define how the display would interact with the memory and CPU. Then, you could add support for graphics. The source code for the Kowalski Simulator is available to build on. Keep in mind, if there is no actual hardware design for the display, your code would only work in the simulator's environment.
