Sorry for the "Insidious" , i translated french to english and may be the meaning of the word is not exactly the same...
I want say, more or less , it is an hidden way to force user to donate.
I'm not socialist , in fact i don't care about politics at all. But it is real i don't like the today society where that the only things that count is money and profit.
I have a donate button for Atomic, and users are free (never forced) to click on ads on my website , and that cover more than my needs concerning development of Atomic. I got some donation up to 300 USD!! Generally is around 20USD. Donation and adds give me a average income of 800 USD/year , largely enough to pay my internet hosting with illimited bandwith and huge storage.
Of course all users don't donate , and i don't blame them , i didn't created Atomic with Profit in mind.
I like frankness , If something is a paid software say it is a paid software. IMHO : GameEX, Maximus and Hyperspin are paid software. From the 3 , Only Maximus claimed that since the begining.
and i don't say it does not worth to pay for that software. They are good , and I understand you can pay for them.
But as i already said in the past, Don't give money to FrontEnd Developper , Give your money to Emulator's Developper. The real magicians are these guys , not a Front End Dev.
