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

[deathblade200]

god I really want to bitch slap the people that keep saying to get a grip for the vita...grips suck giant donkeys balls, uncomfortable as hell, and just look hideous how about they just not ruin a good emulator with annoying backtouch...hell don't even try to play prboom with the backtouch enabled or you are in for a world of hurt and anger

Ok I will do that.

But consider the change to the RETR0 folder idea. The other icon set uses this and you can copy the whole lot over using vitshell mark all and copy easily.

Great icon set you've made well done and thanks again.

do you know how annoying as hell it is to go through and try to figure out which emulator uses which id? and worst part is the ids are always changing which fucks up the whole process so its better and faster to just learn how to edit a vpk

If you can shut off backtouch and it doesn't come back the next time you run the emulator, it shouldn't be a big issue. I personally dislike the back touchpad- it strikes me as mindless oneupsmanship on the part of Sony's hardware designers- but it shouldn't be a dealbreaker if it can be disabled.

1. Make your own vpk for each emu (replace params.sfo, and icons to your taste, repack to vpk)
2. Install.
3 to update just unpack the nightly vpk and replace the eboot.bin for each emu in ux:/app/

4. Profit ?
Anyway it save a lot of time


For the rear touch, you can build your own RA with front instead of rear touch support. I did it. No more twisted fingers.

Any chance of instructions of what to change?

Hi folks! Per-Core Config is working on latest builds? I'm trying to configure input keys for each core, but applies for all cores L1 and R1 for Save/Load State (just for SNES/GENESIS emulators, but not for PSX Core) Any workaround?

Hi guys, @frangarcj just got dynarec working for gpSP! So GBA emulation should be getting much faster on that core soon-ish.

Hoping for full speed Megaman Zero. Great news.

Ok, I'll try to explain some steps

1. Take Snes9x2005.vpk and unzip it.
2. Search and Replace the icons in the folder just extracted (be careful, not all format compatible, let's google for it).
3. Replace the param.sfo (download vitasdk, inside bin folder, there is vita-mksfoex[.exe].
4. In a terminal execute vita-mksfoex -s TITLE_ID="SNES00001" "Snes9X 2005" param.sfo
5. Copy the param.sfo you just created over the param.sfo in the vpk you extracted.
6. Re zip the vpk (I can't tell if compression level is still needed to be set to 0) and install. Take care of the file structure, that must be the same as before it was unpacked.

Next time, just extract Snes9x2005.vpk from a nightly, then copie eboot.bin in ux0:/app/SNES00001/.

For front touch support, you need to set up the sdk but i'll not explain those step. just look for input/drivers_joypad/psp_joypad.c in the retroarch source tree. Then replace SCE_TOUCH_PORT_BACK by SCE_TOUCH_PORT_FRONT all over the file. then compile.

Of course you need to setup the vitasdk, vita2d and maybe some other dependencies. I'll not explain those step because of space and time needed. sorry.

Ok overlays are working again in the latest build. Is there a way to add scanlines if your already using a border?

You can't combine overlays from the menu.

One way of doing it would be making an overlay that combines the two. The overlay is just a couple of PNG files plus one textfile, it should be easy to understand and edit.

Ohh - let us know on that, I'd be delighted.

i got it working with 1 game thus far: Skyroads. slow as hell but works.
any apogee titles i'm trying are not responding to controls most of the time with JOYKEYS.

Hmmmm cool thanks =] That would be a neat feature though

Was going to see what the current state of gpSP is so I have something to compare it to when the build using dynarec is published, but it seems gpSP is still not loading roms. Thought maybe the emulator needs a BIOS, I have it in ux0:/data/retroarch/system but no dice. Does the name need to be anything in particular(filename or extension, upper/lowercase, etc)? Or is the emulator still broken?

So now that gpSP for RetroArch Vita is getting Dynarec tonight, is it going to be better than mgba?

gpsp needs a bios yes.

gpsp needs a bios yes.

I have a bios, is there a particular naming convention it needs? I am putting it in the bios directory that RetroArch says it is looking for a bios(ux0:/data/retroarch/system). It keeps looping back to the UI where I load the roms.
