With AtGames devices they commonly mention if you go to imuga.com you can download more games for their SD card sites, but if you currently go to it the website just searches for ads. A few months back the domain expired and some other company did the hostile take over the expired domain.
So now you can't download the games any more, so now you must use the waybackmachine to even view the website.
The website dates back to 2013, which tells you to go to another website which now links to a trap site that trys to tell you have a virus and to call a number and give money to them to remove the non-existant virus adware spyware. What this trap site use to be is trailware site, you had to have a subscription membership to download more games.
The trail games were panic lift, logic dial, flash memory, sparkling truffle, and mirror mirror.
As far as I know these games are commonly included with units such as the Sega Genesis Ultimate Portable Game Player and the retrogen handheld.
As for the rest of Imuga.com there really isn't much to talk about other than a dozen legal disclaimers, with atgames owning the oem rights to distrobute sega products not only from the genesis but all the way from the master system to the dreamcast aswell as non-platform products, in other words arcade games. But AtGames hasn't done that at all really, a portable saturn would be nice.
They also had a guestbook, which amounted to 10 comments to April 2016. Currently I have not found any where to download these .bin files. Most of the games are really not worth a download.
