As I attempt to play all the Sonic games, some are difficult to play or lost to time. I will be filing information on these here.
1. Sonic Kart 3DX
- Platform: Mobile (Java)
- Status: No ROMs leaked to public, copy known to exist
The above video shows someone from Japan playing this mobile game. It appears to be a 3D kart racer, but with no items. Players would be able to compete each other online, or post their times to leaderboards.
This is one of the mobile games that was part of he Sonic Cafe service – a bunch of mobile games (with network connectivity), available only in Japan. Due to the limited Japanese-only release, many of these games were not backed up by fans.
This person has the game on the original device, so hopefully they are willing to share the ROM so that this game isn’t lost to time.
2. Sonic Athletics
- Platform: Arcade
- Status: No ROMs, not much interest in backing up.
Available only in Sega’s Tokyo Joypolis, this arcade game looks to be a collection of three events based on Mario & Sonic at the London 2012 Olympics, but without Mario & Co. There are eight cabinets in a line, all with a treadmill and a button.
As this is only available in one location (and I’m not sure if it’s still there or if the 2016 and 2020 versions replaced it), along with it being built for unique inputs, it’s not an easy game to preserve – even if someone wanted to do so.
As the 2016 and 2020 arcades are based on the Mario & Sonic series, I won’t be including them here. Athletics is only here due to it’s unique branding.
