Open RinMaru opened 8 years ago
There is no longer a stable method to test and / or release. Sony did away with the open development support and the new generation of CFW is more or less a bunch of low-level hack support.
Is this possible in the future when the vita is hacked again. It cant be completely out of the question.
Would the Vita even be capable?
I think the hardware should suffice to run reicast.
So just gotta wait till we can get inside it?
Or call the Sony customer support and tell them how angry you are that you can't run custom software anymore. Maybe they give in and bring open development support back, I'm not really optimistic though.
Lol well some hacker is bound to open it up in time until then i'm just glad it possibly could be done.
https://bitbucket.org/cirne/vita-toolchain/ https://github.com/vitasdk Dont really now much but perhaps this would be somthing to keep an eye on.
Heres the official sdk https://psm.playstation.net/static/general/all/en/psm_sdk.html
The various methods they are currently using to launch custom software either require you have an older version and exploit the unpublished Unity development tools or security holes that allow a simulated crash to run unsigned code. It would infer that any variation not using the official method of registering with Sony as a software development company is a hack. Usually that means they will target the software to prevent it.
With sony slowly killing off the Vita it's not going to be long before we can all have our way with it. At the moment a vita port is not a priority I guess but it doesn't mean it can't happen since the Vita is more than capable of running Riecast?
They're not killing it off, though. It's actually a requirement that all PS4 games support remote play and many see releases of a title alongside a PS4 version. It will never be as simple as a port.
is it possible though would Vita handle it? thats all im asking at the moment.
That depends on how much of the hardware is available to the method used to deploy it
The full power of the Vita should handle it though correct?
Until some method for actual tests, the only answer you will get is speculation. Maybe it can, but specs on paper may not reflect specs available per app. Regardless of how the question is worded, the answer remains "uncertain"
The ps vita is now fully hacked (you can run homebrew on 3.60/3.65/3.67/3.68 firmware with henkaku http://henkaku.xyz/). OpenGL has been port (https://github.com/Rinnegatamante/vitaGL/). The cpu is a ARM Cortex-A9 MPCore clocked at 333 MHz that can be overclock to 444Hz. The gpu is a PowerVR SGX543MP4+ clocked at 166 MHz (up to 222MHz)
Intruiging, thanks

Note: You need 3.65 or lower to make it a permanent CFW.
@LoungeKatt on newer firmware you have to reapply the hack after every boot
@frstrikerman That is correct.
This would be amazing, h-encore will allow us to play it
I posted this issue in the vitasdk chat and its seams that vitagl is lacking features we will need like shaders
Has there been any process on this? Is there a need for funding this effort?
PSVita doesn't have the hardware specs to run this emulator.
it actually does, just barely, but it’s too much of an exotic platform to be important atm

think this can be closed at this point hard to believe i was requesting this back then lol

I'm actually working on vitaGL for new features for some projects i have in mind (final target would be to make sure that vitaGL is ready for a DS emulator port). I think this will make vitaGL more suitable for a reicast port too. As for shaders, frangarcj (the main dev for the Retroarch Vita port) has a working prototype for SceShacccg module usage on Vita (SceShacccg is a runtime shader compiler made by Sony and bundled inside PSM Runtime app. Users will need to run a dumper to extract said module from the DRM Free PSM Runtime pkg and then they'll be able to use said runtime shader compiler with vitaGL (i plan to integrate sceShacccg into the lib as soon as frangarcj releases his working prototype publicly).
@skmp not at @ ~400mhz it doesn't, and it doesn't have a real opengl solution. Gxm is ...
Not to mention using a wrapper gl lib like was used on ps4 port is just not going to cut it. Which is what vitagl is ( partial gl -> gxm ).
Whoever is backing this madness, I'd do it but it wouldn't run fullspeed even if vita can be 'overclocked' to it's real theoretical cortex-a9 speed or at least close > 1.5ghz.
I do not however have a vita || pstv and the bounty wouldn't be enough to even recoup the $ one would cost.
This time I'll agree. The 'lets do all crazy ports' era is over :p

People who are saying that Vita's hardware is not enough are wrong.
I have tested reicast on my old Galaxy S2 Plus, which has dual core Cortex-A9 (Broadcom BC28155CPU). The most recent Reicast build works on it, even if I underclock it to 600mhz.
From my testings it is not like there is that much of difference between 600mhz vs. 1,6 ghz overclock on that Cortex A9 core. Yes on 1,6 Ghz its faster, but its not night and day difference. Even on 1,6 Ghz it cannot get 60FPS on SoulCalibur, maybe I was GPU bound? But on 600 mhz you can get 30-40 fps in that game. On Ikaruga it is also not full speed, but playable at 30fps
GPU on that SOC is Broadcom BC28155, Vita's PowerVR SGX543MP4+ seems to be more powerful than that, in some tests it gets more than 30% performance increase and in others double performance and in others its pretty much on par.
https://www.notebookcheck.net/Broadcom-VideoCore-IV.116484.0.html https://www.notebookcheck.net/PowerVR-SGX543MP4.115852.0.html
Vita has 4 core CPU while phone I have tested has 2 core CPU. Phone runs Android 5.1 (CM 12.1 ROM) and it eats a lot of resources on that old hardware.
I do not know how much of a difference we could get on Vita's game OS with 4 CPU cores and 30% stronger GPU, but I think some games would be playable for sure (maybe not at full speed, but still). Also we do not know how performance would drop without fully utilizing Vita's GPU and relying on VitaGL, but its not like its impossible, it is possible, just need to port this thing and try it out, maybe this emu would make some games playable on our beloved Vita's.
With recent Deadalus X64 VitaGL port, and seeing that Super Mario 64, Mario Kart 64, Wave Race 64 and some other games run pretty good at Vita's resolution with 4X MSAA, I have hopes that some DC games could possibly run on Vita, we just need some love, its not like crazy ports era is over. Think about it, we can even run N64 on Vita now, even without using its GPU to its full potential. Why not try to port reicast?
The major problem for vitaGL usage is that vitaGL is basically GL1 (there are some features from GL2.x subsets like precompiled shaders support but it's mostly GL1) whilst reicast renderer requires at least GL3 if i'm not mistaken (except for the soft renderer but i'm not even considering it due to the fact it would be a slideshow fiesta on Vita's CPU). I would be more than interested in helping working on a Vita port however if someone's willing to pick the task.
Being able to play RE:CV on Vita would be indeed dope.
i am willing its just i cant find any one to help with this port.
so any one wants to help on the reicast port on psvita?
Would the Vita be capable of Dreamcast Emulation? Is the Vita in the cards for Porting?
