I have an old flash games site running for years, and still getting traffic. I am looking for the best way to save it somehow, I am guessing it will be non-functional after browsers this year stop supporting flash?
Adobe's recommendation remains only: convert to modern technologies instead of using Flash.
Well, I really left it running for ages with little to no maintenance, I guess then its too much work, maybe will analyze what are most popular games and rebuild only those...
Rebuild is not a solution. In case, the games are not mine how could be rebuild?
If you can't rebuild (and certainly only the original author can rebuild, if anyone can), then for almost all web users, all Flash games and all other Flash sites will be useless. A few dedicated hobbyists may be able to make things work, but the chances are, with 99% of their audience gone, the people paying to keep these old sites alive will stop paying and they will go.
