Just thought I'd post this up. I apologize if this is common knowledge, but it took a bit of digging for me to get all info, so I thought I would share my findings here. To be short and sweet. It can be done and it works perfectly. The only drawback I have found is screensaver cannot be set to run_game as Mamewah doesn't seem to know how to close the game before beginning the next one. I set mine to movie which is almost as cool.
Here are the basic steps. I need to give credit as others have paved the way. This is not my discovery I am just sharing. Info pulled from:
http://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Number=298226&page=0&view=expanded&sb=5&o=&fpart=1&vc=11. Copy all mamewah system files to Windows 7 syswow64 folder. Do not replace any that are already found.
2. You will also need to find the following files and copy them to the syswow64 folder
dx7vb.dll
dx8vb.dll
3. Now open the command prompt using administrator privileges and navigate your way to the syswow64 folder.
4. now each file needs to be registered. Type each of the following commands:
regsvr32 COMDLG32.OCX
regsvr32 MSCOMCTL.OCX
regsvr32 MSCOMM32.OCX
regsvr32 dx7vb.dll
regsvr32 dx8vb.dll
regsvr32 MSVBVM60.DLL
regsvr32 PaintX.dll
5. Set MameWah.exe to always run with admin privileges.
Couple of other things that I have done to help MameWah run more smoothly at least visually. (I had noticed each time it loaded you would briefly see the task bar. Not an issue just not very polished looking. To fix this do the following:
1. Set desktop appearance and personalization settings to Windows Classic. Set Task bar to use small icons.
2. Remove any not needed folders from the taskbar.
3. Set the MameWah compatibility to disable visual themes. Also, disable desktop composition.
That's about it. MameWah is now running flawlessly on my Win 7 Pro 64 with no issues. I also set MameWah to always run at startup, but that is a personal preference.
