We've had threads on this emulator on the past but it has not received an update since 2014, so I would like to "update" it with this little tutorial.
For this tutorial, you will need the emulator linked above and DxWnd.
- Extract both the compressed emulator and DxWin to whatever directory you would like.
- In the extracted emulator folder, edit "EMULATOR.INI" with Notepad or the text editor of your choice.
- Under "[RomDirs]", put the location of your zipped ROM files, eg "Dir1=c:\Model2\roms".
- Edit "FullScreenWidth" and "FullScreenHeight" to your desired 4:3 resolution but 16:9 resolution sizes will also work but are not recommended.
- Save and exit EMULATOR.ini.
- Navigate to and run "DxWnd.exe" from the extracted DxWnd folder.
- Click "Edit" and "Add"
- Name the shortcut to the ROM you wish to load, EG "Fighting Vipers"
- For both "Path" and "Launch" navigate to your emulator's exe (32-bit or multicpu 64-bit) and type the ROM name after the exe, EG "C:\m2emulator\emulator_multicpu.exe fvipers"
- Click the "Try" button and your game should launch, if you get errors, exit out try going back to step 2 and changing your ROM directory.
- In the emulator, set the video resolution to "custom", then click "Switch to Fullscreen".
- You should now have a high definition, windowed version of the emulator, ready for video capture (directx/game capture does not work, you must capture the window itself) or streaming!
It changes this:

To this:

This is the only known method to play The House of the Dead in fullscreen and windowed resolutions without recalibrating the gun for each resolution. The results are super crisp and I imagine you can tweak some of DxWnd's settings to crank a few more graphics enhancements for some of the other games but leaving as-is is recommended.
I have been creating cheat codes for Model2 games, so if there are any requests, please let me know below and I will tell you if they can be done or not.
