I've been mulling this post for quite a while now, not in a where do you get teh romz as there isn't any, but more like a simple how would it work. If you're out of the loop then you will know that Sony has all but disowned the Vita as a dead medium and as such there's not much of a first party support at all now. Sure there are a number of Japanese only games but seeing as Japan has all but moved lock stock and barrel to Smartphone usage then even this won't be able to save it.
We were going to say some stuff about Steins Gate last week in our round up of woe, but ran out of room. I thought it would be a rare game but I've seen it in a number of towns now which is more than can be said for Ultimate Marvel Vs Capcom 3 or Disgaea 3, which I'm currently looking for. I know you can buy online but with piracy you could download it and put it on vita without hassle. I know Sony would lose money that way but its not as if they aren't already, you actively have to hunt out the Vita section as its literally shoe box sized area (and nearly all the games will be either football or Minecraft) often hidden away in the guts of the PS3 or PS4 area. Anyway here is a few ideas about how "piracy" may help.
Or as I like to call it ISO. support. One of the biggest bugbears with Vita now is that apart from Txk everything requires a card present in the actual slot to load, sometimes it doesn't register and you have to take it out and re insert it. I know its the pinnacle of first world problems but taking my PSP as an example, I can keep my discs safe, knowing that it will load up from the memory card and play all my games without losing them or switching games all the time.
Yifan Lu is currently working on a Vita SDK which could open it up to much more fun such as homebrew support and bring emulators to the system. Currently this works only on specific firmware with an exploit game from the PSN. Even then it uses the PSP emulator mode to run custom firmware, in other words it works but its not ideal. If this SDK comes through we could see the first true native CFW for Vita allowing more use of the hardware to run stuff we couldn't on PSP.
Flash cards and the like.
This is the main thing that got me thinking about piracy and that. The memory card used in the PS Vita is a custom chip not much bigger than a SD card but much fatter. Its not unprecedented the PSP used Memory card Duo and we had an adapter from Amazon that allowed us to use SD cards in it, its what all my ISO.s run from. With the Vita though they're almost the same size and its not going to work, I've thought about this and you could put a flash card of sorts in the game slot and run stuff from there.
One its bigger and you could easily get an SD card in it.
Two it leaves the memory card slot free to add stuff as well maybe have CFW run from there and have everything else run from the flash card.
There are a few PSP games for downloading at a price from PSN, making use of the PSP emulator to run them on Vita. Much better would be allowing you to add your own ISO.s via card and have them play. Its not as if that old PSP is going to be used much now.
Finally Fan Translations.
We have Criminal Girls Invite Only as part of a lucky trawl through one of the Game's up town. Its originally a PSP game, I don't know what changed between iterations but I do know that its in English now where the original is JP only. Its not the first time this has happened, Makai Kingdom got a fan translation using the PS2 translation as a base, of course you would need a Vita emulator for this to work and at the moment its largely uncharted territory. When that happens expect to see this being more of a reality.
