Hacking The dark days of Vita homebrew are over – GPU usage in homebrew!

[Deleted member 42501]

Hi, you know me as replicashooter and I didn't write this article below:

http://wololo.net/2017/01/22/dark-days-vita-homebrew-gpu-usage-homebrew/

I <gasp> pirated it by virtue of copying and pasting it here (complete with a linkback) as I thought it was so awesome that I peed my pants a little bit and simply couldn't wait to share the good news.

Speaking of pants it appears that certain folks got their knickers in a twist as they only ever keep things legit and love it when others conform to their rules so let's give a warm round of applause for the original authors of all of your warez, I mean the article linked above.

Hugs and kisses - replicashooter

Niiiiiiiice. And just after libretro started working on the N64 emulator, nearly perfect timing

Great work @xerpi! Hope everything goes smoothly!

 

[SuperDan]

Having a N64 & a Dreamcast emulator at full speed would be amazingly cool

Agreed this will be a huge boost to the vita emulator scene as it opens the door to accessing and using one of the most important components of the machine that will turn this into the ultimate portable retro console.

Are you Aurora from wololo or did you just copy&paste her article here?

Very good. My goal is a playable saturn emulator but is good to see some advance with 64 and dream.

 

[GuyInDogSuit]

This is excellent news!

All Vita fans rejoice! Developer ‘xerpi’ who is probably most well-known for libVita2D has started dabbling around with libgxm! Libgxm is the Vita’s 3D graphics API




What does this mean?
In layman’s terms, it means that now, homebrew will be able to access the GPU thus we can expect to see ports of beefier software someday. This means that the days of having everything rendered by software may finally come to an end. Hardware acceleration could bring the Vita various emulators (such as the N64 and maybe Dreamcast) and more demanding homebrew ports/titles. libGXM is quite a complex API according to ‘Xerpi’ so it’s important that everyone does their best at being patient.

Xerpi has said, on Reddit, that he plans to help libretro which means that we could eventually see an N64 emulator up and running.

Awesome! Can I see what libGXM can do?
Actually, you can! Xerpi has kindly provided a demo VPK to show what libGXM can actually do! This makes it the 2nd Vita 3D homebrew after Yifan’s cube demo. The demo isn’t anything special but you can move around, rotate a cube and look in awe at the few lighting effects. Keep in mind, that right now, libGXM is not known well by any developers so development will be slow. You can install Xerpi’s demo right now on your HENkaku/taiHEN-enabled Vita to have fun messing around.



N.B: Please don’t bug Xerpi. He’s doing us a big favour by trying to work with a very complicated library.

This is absolutely awesome news, look forward to this being unleashed on the scene as it will mean emulators come on in leaps and bounds, all aboard the Dreamcast/Vita hype train, choo choo mofos.

I'm afraid that they simply copied my article without even bothering to mention it's copied. Quite amazing how they didn't even change my writing style to at least look like they did something..

 

[Tom Bombadildo]

Yeeah that's sort of a big no no, I didn't realize this was an exact copy-paste as I didn't read the Wololo article.

I've put the entire thing in quotes, and have shamed the user.

Really? You want to get pedantic over copying and pasting such great info from one site to another like some kind of info gestapo even though I linked back to the original article for anyone who wishes to know more? Really?

Well at least it got you to sign up here, welcome, relax, kick off your shoes, relax and wind your neck in, I'm sure you'll have fun here

Yes it seems some people are too lazy to use quote tags.

Please summarize in your own words, the essence of the news you are reporting. Please read the stickies in this forum for a guide. Simply copying the entire source article verbatim is lazy, and tantamount to plagiarism.

Thank you Urza for bringing this to my attention.

 

[Deleted member 42501]

There we go, I've edited the OP now.

Hopefully everyone should be happy.

And about talk about plagiarism on a forum that is chock full of more pirates that a bootleg copy of Monkey Island on a galleon full of stolen treasure.

You people, phew, you certainly are amusing.

Thank you Aurora for the news and tbank you the topic owner for understend the error.

Back to topic: Does this really potentionally improve emulators? Isn't the CPU more important for emulators?

Depends on the emulator, but anything that can be offloaded to the GPU should be. Some things I can think of right off the top of my head are 3d effects and 2d transparency effects in GBA games. For 3D intensive systems like PS1, this is going to be pretty big once devs figure out the Vita 3D lib.

I'm a girl that's liked technology from day 1. Mostly interested in the PSVita/PSP scene but I've always modded my stuff when it's possible, that is

So this is you, I was wondering if that person was a member here, now I know. Nice to meet you.

Still I think is a good thing, I hope to see some nice homebrew games. But I really hope to see better increase in Emulation. Especially ones that isn't RetroArch.

That Genesis plus emulator for Vita can play List Solar ROM, any emulator that can do that is good to me, but the sound quality is bad, and has no save state, or turbo, or anything a common emulator has. Where is the updates on that emulator?

 

[Tom Bombadildo]

Back to topic: Does this really potentionally improve emulators? Isn't the CPU more important for emulators?

Generally, for things like SNES and lower, virtually no GPU hardware acceleration is needed (as the systems are so lightweight compared to today's hardware) so having access to the GPU is not necessarily important for those which is why generally those emulators run pretty well on just about anything.

The GBA uses some 3D effects in some games which is why that's still "iffy" at times, so having GPU access would give a small boost to those more "demanding" GBA games.

But when we start getting into 3D emulation, like the PS1 or the N64, having access to the GPU will give a fairly high "boost" to performance since we can offload most of the GPU work from the CPU to the GPU. It's probably what will make N64 emulation playable on the Vita, and would likely make native PS1 emulation run a lot smoother on those demanding 3D games as well.
