Unhandled exception when attempting to run the bot

[unsightedmetal6]

I am trying to run the bot with Bizhawk 2.8, but it throws this exception:

************** Exception Text **************
System.MissingMethodException: Method not found: 'System.Nullable`1<UInt64> BizHawk.Client.EmuHawk.HexTextBox.ToU64()'.
   at GeneticAlgorithmBot.GeneticAlgorithmBot.get_MaximizeAddress()
   at GeneticAlgorithmBot.GeneticAlgorithmBot.get_MaximizeValue()
   at GeneticAlgorithmBot.GeneticAlgorithm.SetOrigin()
   at GeneticAlgorithmBot.GeneticAlgorithm.Initialize()
   at GeneticAlgorithmBot.GeneticAlgorithmBot.StartBot()
   at System.Windows.Forms.Control.OnClick(EventArgs e)
   at System.Windows.Forms.Button.OnClick(EventArgs e)
   at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent)
   at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks)
   at System.Windows.Forms.Control.WndProc(Message& m)
   at System.Windows.Forms.ButtonBase.WndProc(Message& m)
   at System.Windows.Forms.Button.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Steps to reproduce:

• Put the bot's DLL file in /ExternalTools/ folder.
• Launch EmuHawk and load the ROM.
• Open TAStudio
• Go Tools->External Tool->Genetic Algorithm Bot
• Press Yes
• Create a savestate
• Put in a RAM address to measure fitness
• Make sure the slot number in the window is the same as the savestate/branch you want to load.
• Make at least one button to above 0.0%.
• Click "Run"

Then this exception appeared. I have restarted Bizhawk multiple times, but it still happens.

Also, since it may be relevant based on the exception, the RAM address in question is 0x000096.

Edit: I also get two other errors sometimes:

************** Exception Text **************
System.MissingMethodException: Method not found: 'Boolean BizHawk.Client.EmuHawk.IMainFormForTools.LoadQuickSave(Int32, Boolean)'.
   at GeneticAlgorithmBot.GeneticAlgorithmBot.StartBot()
   at System.Windows.Forms.Control.OnClick(EventArgs e)
   at System.Windows.Forms.Button.OnClick(EventArgs e)
   at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent)
   at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks)
   at System.Windows.Forms.Control.WndProc(Message& m)
   at System.Windows.Forms.ButtonBase.WndProc(Message& m)
   at System.Windows.Forms.Button.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

And another one occurs when I rewind a frame while the botting window is open. It's just a generic message that says EmuHawk has thrown a fatal exception and is about to close. A movie has been detected. Would you like to try to save? (Note: Depending on what caused this error, this may or may not succeed.)

I also tried on BizHawk 2.9.

My bot doesn't support v2.8 due to an issue on the Hawk API that's fixed in the latest Bizhawk dev build. You will want to pull down the latest Bizhawk dev build and compile it using their Dist/QuickTestBuildAndPackage.bat. After that, go to the Releases section, and download the pre-release version v1.0.1 of the bot and install the bot into the latest Bizhawk build. After that, follow the instructions for Source Code Installation.

Don't use the Bizhawk v2.9 RC2 builds.

Let me know if you have any issues.

By the way, I updated the Readme file, so that you can watch how the Bizhawk Genetic Algorithm Bot Source Installation is done. I used Windows Sandbox because it's the best place to show how everything is installed from scratch.

That was the problem! I wasn't using the GitHub-cloned version of Bizhawk.

Thanks, the errors are fixed now.
