That being this.
Sure, Sony has an official one that says (at time of thread creation) 304 titles, but its really not that many. They count a game with a Physical, Digital, and Collectors Edition release as 3 titles...
You can see where a consolidated list comes in handy.
Anyways, hopefully this is helpful, and I'll try to keep it updated as new games get added.
To anyone with a good understanding of Japanese: I know, I know, alot is juumblish. Feel free to note title corrections that are needed.
Any titles followed by (aka [something]) are temporary placeholders, where [something] is the original unjuumbled name.
Also, if anyone finds they've got a Non-JP/HK cartridge on this list that works (or doesn't work) on your VitaTV, please drop a line in this thread, and I'll update it.
