Hacking Emulation RetroArch/Libretro Thread: PS Vita Edition! Nightlies Included

[SonicFan26]

First off I want to thank all the hard work everybody has been doing with Vita Homebrews and Emulators, being able to play classic Sonic games on the go is amazing.

Now about Sonic the Hedgehog 2, there's a little thing that bugs me about Green Hill Zone, that line at the bottom of the screen of misaligned pixels. I find it distracting and annoying, so I did a little tinkering in the video settings and thought I would share with everyone. I'm sure there are people who can probably figure this out on their own, but for all the people who are new to retroarch (including myself) this could be helpful if your uncomfortable messing around with different settings.

What you do is bring up the quick menu within the game and back out to the main menu, then go to settings and video. In the video settings I set aspect ratio index to "custom" and change my custom viewport width to "960" or "640" (if you want the ratio 4:3) and custom viewport height to "550". This will just barely hide that line at the bottom without ruining the HUD and it looks great. Now if you have the viewport width set to "640" you might have to adjust the custom viewport X to center up the screen. Also turn on Integer Scale when adjusting the width and height which will move it up quicker to 960 x 448 and then turn off Integer Scale to manually bring 448 up to 550. I've got some pictures of the settings and results to show you.

One more thing when you beat Green Hill Zone you can set the height to 543 for the rest of the game to give you the whole image, only the first Zone has that line at the bottom, enjoy!

Does theFl0w's PS1 bubble trick still work on 3.60? If so, we only actually need an ePSP kernel exploit, not a PS1 exploit as well.

*Shaft head tilt*

...Er, PS1 bubble trick?

*Goes off for learning*

Oh! Um, since all that the bubble injection involves FTPing into the system, then it SHOULD work!
In fact, since I have my modded PSP 3k... hmm.
Whelp, since there's no new nightly once more, I'll give this a quick swing. No harm in doing so, right?

*Boop*

Yeah, that's always been a thing with Sanic 2. Haha. But that's one way of going about things~

The PS1 bubble trick by thefl0w requires an ePSP kernel exploit however, which is why it doesn't work straight away on 3.60.

However, if the actual PS1 bubble trick itself is still unpatched on 3.60 (I believe this to be the case) and we're simply waiting for somebody to release an ePSP kernel exploit for 3.60, then great - it means we don't need another PS1 exploit in addition to the ePSP exploit.

Then good news: The Bubble cloning does work (Tested with Klonoa - Door to Phantomile if it wasn't obvious enough).
(I'm so original with the icon)

...Aaaand of course the game itself doesn't work.

...O-oh please, you flatter me. (^^;;
It's not like it's much, really.

NEW NIGHTLY:
We lost a whole 0.1mb on the latest upload.

That is all.

*Five minutes later*
Yep, no differences. Carry on.

Sega CD save loading doesn't seem to be working with Genesis Plus GX, at least using the preexisting SNATCHER files I have.

Also cool to see you Seong, haven't seen ya in a long time.

As stated, current in-game saving is sporadic when it chooses to work. Recommended to use Save-States as a backup.

Also cool to see you Seong, haven't seen ya in a long time.

Aww... (^^;; It's super neat to see you as well! Been literally forever...

 

[SeongGino]

So apparently the latest nightly was uploaded with more than a 2mb size difference in the ZIP, but currently the download is bugged.

Things are happening...?

EDIT: New Core!(?)

DeSMuME has been added to the latest nightly (Apparently).

 

[jon2491]

Desmume gives me C1-2569-2 error.

 

[laharl22]

Desmume gives me C1-2569-2 error.

For me too

 

[Niko_of_Death]

Aww... (^^;; It's super neat to see you as well! Been literally forever...

Yeah my 64GB memcard completely died on me in like October (and my hard drive that had all my backups) so I hadn't used my vita until henkaku came out.

 

[SeongGino]

For me too

Which probably means like all the other recently published cores, it's not functioning.
Hrmm...

Well, good to know! (Obviously not GOOD but... y'know)

 

[SeongGino]

First off, new Nightly, new cores!

DeSMuME and TyrQuake have been added!
...Buuuuuuuuuuuuuuuuuuuut...

Quake doesn't load levels...

(Crashes at initializing Network it seems...)

...And DeSMuME itself crashes, but in this case, via a standard Vita System error.

So basically, by Vita standards, the core doesn't even function and doesn't even boot the application.

Is there any way to make the retroarch gpsp and picodrive emulators work. They crash everytime I load any roms.

The newest nightly from mGBA works good with alot of games.

 

[Reconzero51]

In order for sram saves to work, make sure to close the emulator by using the menu, quit retroarch. If you hard close it the sram will NOT save

Actually, no, I've done this multiple times (Please see: FCEUmm save testing), and it STILL only saves about... half the time.

Aaaand, again, no, as far as I'm concerned these are core bugs that cannot be circumvented until they are actually fixed.

 

[sj33]

People shouldn't panic. The 3DS version went through the same teething problems of cores not working, cores sharing the same titleID etc. It all got fixed eventually.

Exactly we should remember that RetroArch not even was released yet, as VPK.
All we have are developer snapshots and nothing more.
Developing something such complex needs time even when its mostly "just" porting.
