First : legal reasons, sorry forget about TxK
but .. second, even more crippling reason .. I don't think there's any manufacturer left in EU/USA of PS Vita cartridges, I did try to ask "a bit there and there" the answer been like "they all shut down".
Unless someone created some hack that allows you to put stuff on a SD card I'd have not a clue how you'd do a physical release, rumors are there could be someone left in China/Asia still making those but probably "in the realm of thousands of pieces" and we don't really know who/where/how much would that cost.
I think it's a pity as I think the Vita still is a really lovely machine, certainly the original one had the most gorgeous screen ever seen in a portable device.
But yeah "making physical copies" .. HOW ?? .. that's the problem ..
Also don't even know legally how that thing would pan out, I did ask for curiosity, still waiting for answers.
But yeah "we may be a bit too late for that"
