Hi,
sorry, I missed your message 🙁 It is very good idea, but there are two troubles
1. Google policy
2. Trademarks and google policy
Each game logo or custom image is potential trade mark problem and can lead to Magic Dosbox ban on google play. You can have custom images, but I can’t create sharing service where these images can be shared. Then there is another problem what google introduced only few weeks/months ago and I don’t want deal with that. They introduced new special rules for apps what shares people’s comments, votes etc. Maybe it is not so bad like I think, I checked these rules only very quickly, but I am not a lawyer. But because mDosbox was suspended 3 times for nothing…I simply don’t want do that..
