The European/PAL version, which did receive a physical release, runs at 50 FPS, slower than the intended frame rate.The Sega Genesis Mini and Nintendo Switch Online ports thankfully have proper emulation. and, by proxy, means you have to beat each game in one sitting and makes it impossible to unlock the Wily Tower mode as a result. The Ultimate Portable Player version theoretically shouldn't have this issue because the game is being emulated, but doesn't replicate EEPROM saving for some reason. The initial Sega Channel release in North America and the later Sega Genesis Ultimate Portable Player re-release don't allow for saving note Saving games back in the day required battery backups in game cartridges, and the Sega Channel version was just a temporary online download that would be wiped when the console was turned off.
