They were a big step up from the original nintendo cartridges we blew in and wiped with alcohol to keep Tyson winking, but I went the Sega route as Genesis was a better system at the time, but that of course is debatable. Happy people still are interested in the archaic gaming systems.

The softer curved design of the PAL versions of these cartridges casings always appealed to me more than the chunky ones sold in the US.

I never understood why they were different though.

On the S-RTC, it was used in that specific game to control time ruin events. When you start the game you're asked to input date and time, and from there the game tracks time to enable certain events.
