PS Vita破解新停顿：已可经由过程HBL运转MD摹拟器

　　前几天，破解PSP破解达人wololo公布了PS Vita的新停HBL正正在开辟的动静。来日诰日他又公布了PS Vita运转HBL的顿已视频！并且肯定最新的可经1.51体系也出有启堵之前阿谁缝隙！

　　如前里所述，由过运转最新固件更新并出有启堵掉降PSV的摹拟缝隙！几天前日本开辟玩家Teck4公布了一张图片：正在PSP摹拟器上运转了“hello world”，破解我当即联络了他并且获得了Mamosuke的新停帮闲。没有暂后我便确启认以操纵那个缝隙使HBL运转！顿已(传闻Teck4也操纵那个缝隙正在做进一步的可经开辟，但没有晓得他已到甚么程度)。由过运转

　　上里那个视频便是摹拟PS Vita正在运转PSP的Megadrive摹拟器，履止的破解是名为《Sonic & Knuckles》的游戏！

　　Update: one important clarification: this video shows HBL running on the latest firmware 1.510. The firmware update that happened today does not patch the exploit, unlike what some sites are saying.A few days ago Japanese developer Teck4 posted a picture of a “hello world” running on the PS Vita through the PSP emulator. I contacted him immediately with some help from Mamosuke, and I soon got enough information to start working on porting Half Byte Loader to this exploit (note that Teck4 is also working on exploiting this vulnerability further, but I don’t know how far he’s been)。

　　What you see in the video below is the game “Sonic & Knuckles” running in picodrive, a Megadrive emulator for the PSP。

　　1. THE GOOD

　　Yes, I’m running an emulator inside a hacked emulator on the Vita, that’s kind of cool. There’s lots to say about this ongoing work, but first let me state that, for once, this HBL port is entirely my work, except for the underlying PSP exploit which is initially from Teck4. I’ve been testing other people’s work for a while, so it was about time I got back to coding myself

　　Now that my ego is satisfied, let’s move on to the details of the video below. I have good news, bad news, and ugly news. But first check the video below, the first usable hack on the PS vita, 10 days after the console is released

　　This is technically HBL rising from the deads, running on the PS Vita, and loading the picodrive emulator. Usually I would show you the entire loading process, but you’ll understand that some of the things I do (in particular the exploit used) need to be kept under wraps until the whole thing is made public (if it is ever made public, read more below). I hope however that given my reputation on the PSP scene this won’t be categorized as a fake, please understand that I can’t show much this time. Picodrive is one of the easiest homebrews to run on HBL for some reason, that’s why I’m using it in my test. People who’ve used HBL a lot in its early days will recognize the sound glitch, this is some 22kHz sound being played at 44kHz, or the other way around, I can never remember. That’s because the PSP emulator is using PSP’s firmware 6.60, for which HBL’s syscall estimation code seems to be a bit useless. (I am still pending some reply from Teck4 to see if it would make sense to “officially” involve more hackers on this port, and see if we can fix those syscalls problems. For now, as far as I know I’m the only one who made it that far on the Vita, and I feel kind of lonely on this new hacking scene ^^)。

　　Another good piece of news for me is that before HBL could run Homebrews so “smoothly” on the PSP, it took us several months (I can’t remember exactly, 3 month maybe before we got it running “ok-ish” ?)， while here it took me 3 days to get it to a usable state. Clearly, we didn’t lie when we said HBL would be portable to new game exploits

　　So, that’s the good, I’ve proven to myself that it is possible to run HBL and actual homebrews on the Vita. With little effort, HBL could probably be improved to some extent on that exploit, and run a few useful homebrews。

　　1：好动静

　　PSV能运转HBL，战便宜法度，并且操纵缝隙能够没有竭改进HBL，从而运转更多的便宜法度。

　　2. The bad

　　There are slightly bad news too. One is the syscall estimation algorithm being busted, as I explained above. I discussed a bit with JJS, and it is probable that if a function is not imported by the game itself, we might not be able to use it at all. I’ll have a closer look (if I decide to dig further on this) to see if this can be improved, but that could greatly limit the amount of homebrews that can be played on this。

　　Another issue is that the time currently needed to load/run homebrews for the “end user” is a bit too long to my taste. In its current state, for now I don’t think this is (or will be, even if improved) very useful for the end user. Basically, if I want to run PSP homebrews for now, it’s way easier and cheaper to do so on a PSP, even on an unhacked one, through HBL. So, the overall uselessness of this makes me wonder if it should be kept secret in order for other hackers to do some research on it, or if it should really be released. I wouldn’t like people to point fingers at me if Sony patches some  security flaws after this exploit goes public… I won’t take that decision alone (since I’m not the only one knowing the exploit)， obviously, and there’s still time until the US/EU release, but I’m seriously considering the options here。

　　I have also yet to find a “good” way to install and run homebrews. I thought I had found a convenient way, but it didn’t work as expected. I’ll dig more on that, but it seems the PSP filesystem, as seen through the emulator on the vita, is a bit tricky and sneaky…
