RE: Sukura wars 1&2 (Sakura Taisen 1 and 2)
Tested this for a while and I would say it can be moved to playable, special attacks aren't really crashing, however I can understand the reason of potential crash for people with older/weaker hardware... by running out of memory:].

Unfortunately this game uses tiled textures(it's a port of an old game), and for one effect it does something very weird that our texture cache doesn't and likely can't handle well.
Basically it uses 512x512 textures to do some colorful lights and instead of advancing prim, it advances texture address to match following tile as can be seen:
       
~not hard to guess this translates to a lot of 512x512 textures being cached per frame and that's a serious performance problem especially when those textures change every frame and game runs it at 40fps.

In the end it's not exactly game breaking issue, even less thanks to a feature of the game itself which allows to instantly skip those animations at any moment by just pressing "start". Auto frameskip also helps since every frame skipped = lots of textures less to cache.
