if (var.test == "0x003CAD") then


should be

You only need to convert it to a string to display it.

By the way, you can call almost any windows DLL functions from GlovePIE, not just GetDC, ReleaseDC, and GetPixel. Even DLL functions you write yourself.

Ha! I see...

Code:
// draw red pixel when left mouse button is down
if (Mouse.LeftButton) then
  var.hdc = USER32.DLL.GetDC(NULL)
  var.pixel = GDI32.DLL.SetPixel(var.hdc, Int(mouse.CursorPosX), Int(mouse.CursorPosY), 0x000000FF)
  USER32.DLL.ReleaseDC(NULL, Int(var.hdc))
  debug = '0x'+IntToHex(var.pixel, 6)
end if
It's too bad I have no Windows programming experience and I can't think of anything cool to do with this stuff. Right now I'm going through some gigantic Windows API reference thing and waiting for something to pop out at me.

Okay, this may be a fool's errand, but I'm looking at this function called ReadProcessMemory that (surprise) allows you to read memory from a specified process. Most emulators I've messed with have had a built in cheat search that allows you to check the rom's memory and see how certain values change, usually giving you the address of the memory.

Now, say I'm doing a cheat search on Street Fighter 2 on ZSNES and I find that a certain piece of memory changes to 3F whenever I do a dragon punch. If I know the value to look for and the address in ZSNES, is there any way to use that information and call that ReadProcessMemory function from within GlovePIE to check to see if that bit of memory has changed? If so it would supplant that GetPixel method you showed me and allow for some very, very crazy things.

Good god, that GetPixel method works wonders! I've been combing through NES games, adding rumble support where possible. So far I have scripts for Excitebike, Mega Man, T&C Surf Design, Dr. Mario, and Little Nemo. The only problem is they'd require the user to be using VirtuaNES at a resolution of 1024x768. Other emulators running at the same resolution could still work, but I haven't tried it. Still pretty awesome though.

Thanks for letting me know about this program! I've been messing around with it for about 2 and a half hours now Embarassed

It took me that long to get my wiimote to rumble when Zone Alarm's "traffic" bar goes to the top. Using that program is hard for me Sad

The problem with ReadProcessMemory is that you are accessing the emulator's memory rather than the ROM's.
Basically using ReadProcessMemory would be like doing a cheat search on the emulator itself.
But you would need the exact same version of the emulator, and ReadProcessMemory will only really work for global variables that the emulator stores. The ROM's memory, and anything else that is loaded dynamically, would be loaded into a different memory address each time, so you wouldn't be able to find it.
I don't think it is worth the effort.
