Update on Jaguar core: Audio Driver edits add maybe 1 fps. Not worth it at this point

Here is the error whenever you compile a mednafen-based core (at least the virtual boy core that is):

Also, Here is o2em: https://www.dropbox.com/s/eae4zv5qrp4eczo/o2em_libretro.so?dl=0 I don't know if it works or not as I don't know where to put the BIOS rom

It should work though.

I figured out how to get cores that require a BIOS to work

To get those cores to work, just change the system_directory in the retroarch.cfg to where you want your bios files to be placed. You can just use the one I edited too

Just make sure to delete any files in the top folder before adding the new cfg file. Also, make sure to add a folder called BIOS in the same folder that holds your retroarch.cfg

Here is the edited retroarch.cfg: https://www.dropbox.com/s/yqy9ozbi9u1ozxl/retroarch.cfg?dl=0

The so file I attached above works fine

I'm working on getting the 4do core working. Should be up soon.

@zhongtiao1 Can you post the makefile you are using to build the mednafen core? Some makefiles need different variables to be set. I usually use the Linux or Linux-portable platforms as basis.

Using oprofile will tell you a lot of information about what functions are causing bad performance of some cores.

Here is a little guide by pcercuei: http://boards.dingoonity.org/gcw-development/(question)-how-to-profile-application/

For example, this is the result I get from catsfc_libretro.so:

It seems most of the cpu time is spent in egl_gallium driver. And, maybe, optimizing WRITE_4PIXELS16 can improve performance.

Here is the 4DO Core: https://www.dropbox.com/s/483ldwx2p21ey0z/4do_libretro.so?dl=0

Animations are actually pretty smooth, I would say they are about 10-15 fps. When you actually play the games though, lots of screen tearing occurs. Lots of lag also happens at user movement on screen. Game play is at about 1 to 3 fps

Here is the pcsx1 core: https://www.dropbox.com/s/oqnoud2hlujpm5v/pcsx1_libretro.so?dl=0
It's has the same problems as the 4DO core, so I believe they both have the same problem. No screen tearing in this core though.

It seems most of the cpu time is spent in egl_gallium driver. And, maybe, optimizing WRITE_4PIXELS16 can improve performance.

@the_gama How do I do the opcontrol over telnet correctly? I've started profiling, but whenever I try to run the retroarch executable I made on my computer, it won't read any Atari jaguar rom I through at it. I am using the virtualjaguar_libretro.so. What am I doing wrong?

Makefile from mednafen-based cores: https://www.dropbox.com/s/trct6f2pe6295q7/Makefile?dl=0

the_gama · « **Reply #25 on:** February 19, 2016, 03:33:26 am »

Ok, here is what I do:

1) Build the core library with DEBUG flags enabled, you can try:

Code: [Select]

make DEBUG=1 platform=gcw0

Or put those CFLAGS manually in the Makefile.

2) Create a folder called 'retroarch' inside the SD Card, using an ftp client or the OPK Manager.

3) Copy the retroarch executable (not the OPK), and the libretro core there.

4) Connect through telnet to the gcw0

Code: [Select]

telnet 10.1.1.2

5) Browse to the retroarch folder and init the profiler with the following commands:

Code: [Select]

opcontrol --deinit
opcontrol --no-vmlinux
opcontrol --separate=kernel
opcontrol --init
opcontrol --reset
opcontrol --start

6) Then, also from telnet, start retroarch:

Code: [Select]

./retroarch -L catsfc_libretro.so "roms/Mega Man X (Version 1.0).sfc"

I like to load a rom directly to skip the rgui menu.

7) Then let the game run for a couple of minutes, and then exit retroarch by pressing Select.

8 ) Finally stop the profiler and check the results:

Code: [Select]

opcontrol --stop
opreport -l ./retroarch
opcontrol --deinit

About the Makefile, I think you are missing the CXX compiler.

Code: [Select]

else ifeq ($(platform), gcw0)
   TARGET := $(TARGET_NAME)_libretro.so
   CC = /opt/gcw0-toolchain/usr/bin/mipsel-linux-gcc
   CXX = /opt/gcw0-toolchain/usr/bin/mipsel-linux-g++
   AR = /opt/gcw0-toolchain/usr/bin/mipsel-linux-ar
   fpic := -fPIC
   SHARED := -shared -Wl,--no-undefined -Wl,--version-script=link.T
   LDFLAGS += $(PTHREAD_FLAGS) -lrt
   FLAGS += $(PTHREAD_FLAGS) -DHAVE_MKDIR
   FLAGS += -march=mips32 -mtune=mips32r2 -mhard-float

It will be interesting to see the profiler report from the pcsx1 and the jaguar cores.

I can't get Jaguar Roms to work over telnet for some reason, sorry.

the_gama · « **Reply #28 on:** February 19, 2016, 02:08:45 pm »

I think pcsx1 core (pscx_rearmed) would need a MIPS Recompiler to work decently. If I am not wrong, I remember they used Ari's mupen64plus recompiler with some modifications. It may be posible to do something similar with Nebuleon's dynarec but this is a huge task.

By the way, it seems a Frameskip option was implemented to pcsx_rearmed core some time ago. Maybe that option can be implemented in other cores too.

Would you be willing to test the jaguar core @the_gama ? Also, I believe the 4DO core has the same problem as pcsx1 does. It stutters in the same places.

I also saw some references to frameskip in the jaguar code though I haven't delved further to see if they are legacy or if they actually do anything at all.

I searched in a couple of cores for FrameSkip option. I found some references, but the actual implementation was completely removed from the sources.

@zhongtiao1, I will try to, I don't have time this weekend but I'll give it a try next week.

If you haven't done already, you can try:

Code: [Select]

./retroarch --verbose -L virtualjaguar_libretro.so "roms/some_jaguar_rom"

The --verbose option will make retroarch display lots of information.

By the way, I have successfully built mednafen_pce_fast_libretro. It runs Akumajou Dracula at full speed

Some games (according to the virtual jaguar compatibility list) don't require DSP. If we remove DSP, we would gain a large jump in performance, but it would severely hurt the game compatibility. Also, egl_gallium is still up there.

Congrats gama on getting pce-fast to work

I still can't get any of the mednafen cores to work even after adding the CXX compiler.

the_gama · « **Reply #33 on:** February 23, 2016, 01:29:09 am »

@zhongtiao1 It seems, the Jaguar core would need lots of optimizations to run well on the zero.

Currently I am testing other cores to find which ones run well on the zero. I cannot work on this project for longer, so I will try to post all the patches for the cores I have built this week.

I think the main focus should be to find which cores fullspeed and maybe contact a libretro dev to send them the patches. Maybe they can tell a hint on how to optimize retroarch on the zero

.

the_gama · « **Reply #34 on:** February 23, 2016, 07:51:13 pm »

I have uploaded RetroArch_v0.1.opk to Dropbox, you can get it from first post.

The more important changes are that no additional files should be needed, only the RetroArch_v0.1.opk. And that I added some new cores: fceumm, pocketsnes, prboom, pce_fast and ngp.

As I stated before I cannot work on the port for now so I hope someone want to continue working on it.
Cheers.

I played around with this and it's quite nice. GLUI scales well to the Zero's screen. For me it's replaced stand alone Gambatte and Temper for GB/C and PC Engine. If the Neopop and FCEUmm cores ran full speed for everything I'd replace Race and FCEU too. I wonder how well mGBA would run; it's supposed to be a balance between speed and accuracy, but I bet it'd be too slow on the Zero.

Anyways, good work the_gama!

Hi, i am SpikeSpiegel from the Open-Consoles community (www.open-consoles.com). We are specialized on emulation and handheld consoles.
First thanks for all of your works, it's great! I am following retroarch since many years now, this multi-platform emulator is amazing, it's a good thing that now it can run on Zero.

Here i have compiled some cores by following instructions from the first post.

I don't have the device so i can test it. For information, DavidKnight has created a thread on our board: http://www.open-consoles.com/t9579-gcw0-retroarch-development-progress

Thanks guys!

zhongtiao1 · « **Reply #37 on:** February 24, 2016, 03:33:08 pm »

Guys, i'll be working on cores later today. Hopefully I can get the PCFX core working as well as optimising the 4DO and Jaguar cores.

I tried the PicoDrive, SNES9x, Gambatte, gpSP, Mednafen, and PRBoom cores so far.
PicoDrive runs at around 55 FPS, SNES9x ran at 30 FPS, Gambatte ran fine, while the other two crashed back to the desktop.

SpikeSpiegel · « **Reply #39 on:** February 27, 2016, 09:28:03 am »

Hi @Durrsly thanks for feedbacks, for prboom_libretro.so you need to place prboom.wad into your rom folder (available into Makefiles.zip). For gpsp you need a gba bios. Hope this could help you.
