I have these 3 games working on the SEGA Mega Drive/Genesis, but all 3 games suffer from the same issues.
Issue 1 - The game emulation speed is slow. Running the games in Overclocked Gens R57Shell Mod 150Mhz emulator seems to run the games at a normal speed.
Issue 2 - The games' audio/sound effects do not play. The games are effectively silent.
Issue 3 - You cannot select other options the main menu. You can only select the first option (which is fine in the cases of these games).
I do not think I am allowed to share the roms, but I CAN tell you exactly how I made the roms.
How to make the roms:
Step 1: Download NeMul here: https://web.archive.org/web/20171017104107/http://pscd.ru/uploads/files/games/smd/N/NeMul.7z
Step 2: Download the NES roms for Donkey Kong, Mario Bros and Popeye (I know you will be tempted to try out other games, which you can feel free to do so but these are the only games besides Duck Hunt that I could find that ran almost flawlessly without glitches or visual issues).
Step 3: Create a folder, and place the NeMul BIN file into the folder as well as the NES roms.
Step 4: Hold shift and right click on the folder, and choose the option "Open command window here". (If you're a Windows 10 user you will have to follow this guide to add this option back onto your PC: https://www.windowscentral.com/add-open-command-window-here-back-context-menu-windows-10
Step 5: Use this code on the command prompt, making sure that the first name is of the NeMul BIN file, the second name is the NES rom file, and the last name be the output filename.
copy /b emulator.bin + nesrom.nes convertednesrom.bin
Step 6: You can use a checksum fixer on the output ROM which should now load on Mega Drive emulators.
If anyone is able to make a fix for these issues then we should have 3 classic games running smoothly on the Mega Drive/Genesis!
