Well, finally ! Here are the screenshots. I think I'll give up on imageshack for temporary hosting of images.http://imageshack.com/a/img923/2327/io0SLQ.jpghttp://imageshack.com/a/img921/866/uMKGp5.jpg
For the second screenshot, I tried to equip Lisa with Emp. Kaboom, which Bellamy can equip so I assume it needs heavy weapons. But others are less straightforward, like energy pistols, I can't know if they need light weapons or energy weapons or both.
Also, I checked again to be sure that there were no tooltips with the requirements when tapping on an item.
There were many others problems of convenience like that, but I saw no need to mention them since there probably would not be any fixes for an older game (and most would probably require too much work anyway) and since they seem to already have been identified (as is attested by their absence in the other games I tried). I only mentionned this one because I hoped I missed something.
