Dolphin (and pcsx2 as well) doesn't work on windows 98

[CamTron]

Does that SDL.DLL error happen right when you start Dolphin, or when you try to start the game? If it happens right when you start Dolphin, you might try opening it first and then attaching FineSSE to the process. It's possible that FineSSE might be interfering when it tries to load the DLL.

 

As for PCSX2, you're getting the same exact exception, but FineSSE is catching it and shutting down the program rather than Windows. I've never used FineSSE at all, but I'd think there's a way to make it ignore that exception.

 

There's no reason why the developers of both of those applications should be including code that throws those exceptions in a release version that's not meant to be debugged anyway.

I downloaded Dolphin 3.0 from the link in Post #1.

To remove the 406D1388 RaiseException, Patch DOLPHIN.EXE:

16B1E0 55 -> C3

Thanks for your reply. How can I patch it? Do I need to use a hex editor?

Yes.

[junior600]

Yes.

Sorry to bother you, but  have tried to do that with HxD .... I can't find that line...

"Impossible to find 16B1E0 55"

 

 

 

If I search "RaiseException"?

16B1E0 55 -> C3 means go to address 16B1E0 and replace 55 by C3.

Yes.

You need to find 16B1E0 and change the value at this address from 55 to C3.

Did a quick check with the xvi32 resource hacker and it was immediately found.

Does this gamecube emulator (dolphin 3.00) work on windows 98+kernelex 2015? I have tried to run it, but it says me that it is missing a function in "imagehlp.dll" xD You can find the file exe there

http://www.dolphin-emulator.com/download.html?rev=v30&arch=win32

I hope someone can find a solution.

Hardware acceleration needed for D3D 9.0c and OpenGL is not available on Windows 98 with KernelEx. So I think it is impossible to run Dolphin on 98. In fact, Dolphin doesn't work on Windows 2000 if you don't install KEP and other utilities made by BWC. Although gCube 0.3(gCube_nodebug.exe) emulator works on 98, it is too immature and outdated.

 

Old PCSX2 0.94 should work on 98 with KernelEx.

 

Maybe someday old Dolphin 2.0 will run on 98 with KernelEx, but expecting latest Dolphin and PCSX2 to run on 98 is impractical.

I'm sorry to reply after a year xD I have replaced the value from 55 to C3... But now the emulator shows me another different error as soon as I launch a game...

I don't know what does it mean... Is there a guide which explains what I have to edit? For example how did Rleow understand that I had to Patch the value in DOLPHIN.exe in order to remove the 406D1388 RaiseException? How did he know which address it was?


Another thing.... I'm trying to run pcsx2 too (version 0.9.4 or 0.9.5)

The pcsx2.exe showed me this error "The Pcsx2.exe file is linked to missing export KERNEL32.DLL:MapUserPhysicalPages", so I have seen with importpatcher.41 how many functions are missing in kernel32.
MapUserPhysicalPages
AllocateUserPhysicalPages
FreeUserPhysicalPages

I added these functions in stubs.ini (Kstub822) and now the pcsx2.exe file shows me:
"Cannot allocate mem addresses 15000000-5500000, err:8"

I think I'm in the right track to load it. Sorry for my english, I know it is very poor.

I'm pretty sure he used Ollydbg or a similar program to disassemble and debug the code, search for a specific function call, and from there you can change some opcodes and know what offset and bytes to patch.

Oh, I see... I have tried to use Ollydbg and I have found where dolphin.exe calls "raise exception". Now, what should I edit? (this is a old version of dolphin). This is a screen of ollydbg

Spoiler

[rloew]

I used tools I wrote myself to find the location to patch. I have never used Ollydbg.

First I used a binary search program to locate the Exception Code.
Then I used a disassembler to identify the enclosing subroutine.
Analysis showed that no return code was needed and the calling convention.
Dropping a return instruction on the top of the subroutine was the appropriate thing to do.
