Nab the [link|http://www.spiceware.org/downloads/MedievalMayhemNTSC.bin|ROM] off my site then use Stella.
Sadly [link|http://home.houston.rr.com/spiceware/stella.html|my port of Stella] doesn't know how to handle F4 (32K) Atari games - only F4SC (32K + extra RAM) as there weren't any known 32K games w/extra RAM back in 2000 :-(
There's a newer [link|http://smedley.info/os2ports/index.html|SDL port here] that runs my game but has issues that I suspect are because I'm running OS/2 via Parallels on my Macbook. Audio doesn't work correctly and the game speed is inconsistant, speeding up and slowing down. This port of Stella doesn't know about my game so you'll have to change a few settings, especially "use paddles" or Stella will think a joystick is plugged in.
1. start Stella
2. load Medieval Mayhem
3. hit TAB, a menu will pop up
4. select Game Properties
5. on the CARTRIDGE tab set SOUND to STEREO
6. select the CONTROLLER tab
7. change both controllers to PADDLES
8. hit OK
9. hit EXIT MENU
10. restart the emulator for the change to take effect. Under OS X use APPLE R, under Windows and Linux use CONTROL R. You'll get a message "New Console Created" when it restarts.
Once you've done this, Stella will remember the settings if you play the game again later. However, you'll have to do it again if you download a new build.
I also had a problem with the new version Stella were I couldn't control the in-game-menu if I switched it to full screen mode - and after switching it to full screen mode it would always start up in full screen mode. I was able to switch back to windowed by starting it via command line using:
stella -fullscreen 0
