Re: RetroArch Emulator Frontend

I recompiled with the retropie script today and noticed that the SNES emulator is showing odd coloring. It seems like blacks are green. I'm running a 512mb pi with a 128mb split, with the hdmi_group=2, hdmi_mode=4 boot options set. Overclock set to 700. Is the odd coloring due to the new default GL...

Re: Best Emulators for Pi

abishur Thank you for the reply I have tried Retroarch and although it is an extraordinary piece of coding and interesting concept, not wishing to criticize (I am trying to be diplomatic here! One thing I HATE is people being disrespectful of other coders work and complaining!) ,it’s a complicated ...

Re: RetroArch Emulator Frontend

Just an update: A recent change was pushed to RetroArch, which makes the GL core the default core. If everything goes to plan, you shouldn't notice any difference, but if you notice bugs or degraded performance from this change, please report it.

Re: RetroArch Emulator Frontend

Recently, I get error when I try to compile the libretro PCSX core from git://github.com/libretro/pcsx_rearmed.git with the commands ./configure --platform=libretro make. This is the console output: Output: gcc -Wall -ggdb -Ifrontend -ffast-math -O2 -DNDEBUG -mfpu=vfp -fPIC -Wno-unused-result -DNO_...

Re: RetroPie Setup - Auto-installer/updater for RetroArch ga

If DGen works better than Genesis-Plus-GX, I might see what would need to be done to make a libretro port. Could be fun :) Me and the other devs are always looking for more ports. If you want to take a crack at it, check out libretro.h , it describes the API pretty well. There was a more in-depth P...

Re: Big open news!

It seems like they are complaining that there still isn't a register/bit twiddling level interface for them to build their own drivers on . The fact that the video core has a higher level interface that makes people like them who write drivers obsolete is upsetting them :roll: PeterO You know, I th...

Re: RetroArch Emulator Frontend

Presently the ESC key exits the Emulator, is it possible to set a key combination on a joystick to equal the escape key? I tied setting input_exit_emulator = input_player1_l_btn but it doesn't seem to like that (and input_player1_l_btn is defined ;-) ) Beyond that is there a way to assign a key com...

Re: RetroArch Emulator Frontend

Just for the record, recompiling them has fixed the color pallet problem :-D also, I successfully setup my controller, but how would I go about setting up a player 2 controller? If you look in retroarch.cfg, you'll find the options for input buttons. Just copy it and replace "player1" with "player2...

Re: Using dispmanx resources with EGLImage?

While looking through EGL again, I found this interesting BRCM extension:

Code: Select all

/* Multimedia target - created by gralloc */
#define EGL_IMAGE_BRCM_MULTIMEDIA 0x99930B2
Is it possible to take advantage of this yet? I know gralloc is an Android thing, but can it be used now?

Re: RetroArch Emulator Frontend

Shaders using the BSNES XML format should work, and you can find some here: http://gitorious.org/bsnes/xml-shaders Note that some shaders are more performance heavy than others, and at higher resolutions, they can slow down your game. How do you get them to work? I recompiled the latest retroarch a...

Re: Using dispmanx resources with EGLImage?

Well, it's not what I planned, but I found out if you need to update a texture often (like every frame), if you make a seperate EGL context for OpenVG, and instead upload the texture to a VG Image and use an EGL Image to bind it to a GL texture, it's actually much faster than updating it with glTex...

Thanks! One last question, I've seen a couple different links to the github site to use, is there a good link for building RetroArch for the Pi and how to edit it's various config options?

The NES color palette is a surprisingly difficult thing to get just right, and a lot of emulators do it different from each other: http://forums.nesdev.com/viewtopic.php?t=9027 Interesting, if this is the case, is it possible to (easily) tweak the color pallet to fit my TV?

Re: RetroArch Emulator Frontend

A quick post about two things: 1. Due to an update in RetroArch's pixel formats, you will have to recompile all your cores or get degraded performance. Newer versions will still work, but don't be surprised if things are slower until you recompile the cores as well. Is RetroPi using the emulationst...

You should definitely switch from my repo to the official one, since my personal one isn't updated anymore and the official one has a lot more new features, like OpenGL ES/Shader support (too slow to be playable at the moment, but it's being worked on) https://github.com/Themaister/RetroArch Will d...
