Problem loading games - error #2747

Closed jaw9170 closed 3 years ago

jaw9170 commented 3 years ago

Hello,

When using the most recent GIT version of BizHawkm whenever I load a game I get the following:

This happens with any ROM I try to load. This was working at one point. Where am I going wrong?

System.NotSupportedException: The given path's format is not supported.
   at System.Security.Permissions.FileIOPermission.EmulateFileIOPermissionChecks(String fullPath)
   at System.Security.Permissions.FileIOPermission.QuickDemand(FileIOPermissionAccess access, String fullPath, Boolean checkForDuplicates, Boolean needFullPath)
   at System.IO.FileInfo.Init(String fileName, Boolean checkHost)
   at BizHawk.Common.PathExtensions.PathExtensions.MakeAbsolute(String path, String cwd)
   at BizHawk.Client.EmuHawk.MainForm..ctor(Config config, IGL gl, Action`1 updateGlobalSound, String[] args, IMovieSession& movieSession)
   at BizHawk.Client.EmuHawk.Program.SubMain(String[] args)

Thank you, Jason

What's the command you're running? Double-check which characters need to be escaped, it's likely that the shell is eating backslashes.

Thank you Yoshi,

Here is an example of the command being run:

EmuHawk.exe "D:\emu\snes\Champions World Class Soccer.sfc"

All of my SNES roms are in d:\emu\snes directory Trying to run game named Champions World Class Soccer.sfc

If I remove the quotes EmuHawk will run but will nut load the ROM.

Any help will be appreciated.

Jason

So this is from the Command Prompt? And the rom can be loaded from within EmuHawk? I also keep my roms on a different drive to BizHawk but I haven't seen this error before. Try opening the Command Prompt in D:\emu\snes and running C:\wherever\EmuHawk.exe "Champions World Class Soccer.sfc".

Has the loading of ROMs changed? I ask because up until recently, I never had a problem using EmuHawk. The games always loaded.

Yes, this is from command prompt. The ROM can be loaded directly from within EmuHawk, yes

I tried a different game and tried what you suggested. The game loaded fine both in command line and within EmuHawk

Command used:

D:\Emu\GEN>d:\emuhawk\emuhawk.exe "championship Bowling.7z"

game loads fine

If I go back to EmuHawk's directory and try to run the game I get an error:

D:\EmuHawk>emuhawk.exe "d:\emu\gen\championship bowling.gen"

error:

System.NotSupportedException: The given path's format is not supported. at System.Security.Permissions.FileIOPermission.EmulateFileIOPermissionChecks(String fullPath) at System.Security.Permissions.FileIOPermission.QuickDemand(FileIOPermissionAccess access, String fullPath, Boolean checkForDuplicates, Boolean needFullPath) at System.IO.FileInfo.Init(String fileName, Boolean checkHost) at BizHawk.Common.PathExtensions.PathExtensions.MakeAbsolute(String path, String cwd) at BizHawk.Client.EmuHawk.MainForm..ctor(Config config, IGL gl, Action`1 updateGlobalSound, String[] args, IMovieSession& movieSession) at BizHawk.Client.EmuHawk.Program.SubMain(String[] args)

Has the loading of ROMs changed?

The method MakeAbsolute listed in that stacktrace is new, it was added in 7a7522f28.

Unfortunately I wasn't able to reproduce the error. I tried these:

F:\BizHawk\BizHawk-2.6.1>.\EmuHawk.exe F:\BizHawk\Conker.n64
F:\BizHawk\BizHawk-2.6.1>.\EmuHawk.exe C:\users\groom\Downloads\Conker.n64
F:\BizHawk\BizHawk-2.6.1>.\EmuHawk.exe \\192.168.0.16\public\roms\N64\Conker.n64

...and all worked.

jaw9170 commented 3 years ago

Well, that settles that - if you cannot reproduce the error, then the issue is on my end.

I do appreciate your time and effort.

Have a great night!

jaw9170 commented 3 years ago

To further confirm that the issue is indeed on my end, I deleted EmuHawk and deleted all registries entries (had to do this). I downloaded a fresh EmuHawk and now everything is working.

Thank you again and sorry for the red herring.

emuhawk doesn't do anything in the registry. I too want to know what registry keys you found for emuhawk. Maybe you security software marked some executables or directories as banned somehow.

jaw9170 commented 3 years ago

well, it was working. I just updated to 2.6.2 and now I'm getting those errors again. Something changed in EmuHawk that's causing these exceptions.

jaw9170 commented 3 years ago

Reopening issues as multiple users are reporting it.

zeromus commented 3 years ago

Pay attention to what youre deleting in the registry this time when you delete registry data to fix it

jaw9170 commented 3 years ago

It's not with the registry. Not sure what the deal was last time. To be honest, I tried so many things I forget half of what I did. To err on the side of caution, let's leave the registry alone for now.

Nicholas-Steel commented 2 years ago

I can confirm this is fixed after updating from 2.6.2 to 2.7.0 (I also had the issue).
