Neon Enhanced plugin for PSX

Twitch0815

I have not found it requires the speed hack, but I do have my gpu_freq at 525 and just general overclocking but I have not found any problems outside a few glitches in the obscure game or too.

Sorry for my noob question. But WHERE is that option really? I cant find it anywhere.

@Tao it's linked and stated several times in this thread: https://github.com/RetroPie/RetroPie-Setup/wiki/Playstation-1#enhanced-graphics

I tried with Jacky chan stuntmaster, the gfx are considerably better. But even the pi 3 overclocked seems to crash and theres a lot of freezing.
I have not tried disabling the neon mod yet to see if that's the issue but Im guessing it is, as i have a pi 2 which runs the game perfect without the neon mod.

pitty, it really was better.

@Twitch0815 Hi. What exactly does the Neon Enhancement do? Does it get rid of that full screen dithering effect? If so count me in.

@drake999 explained here: https://retropie.org.uk/forum/topic/118/neon-enhanced-plugin-for-psx/7 - not to do with dithering.

I tried with Jacky chan stuntmaster, the gfx are considerably better. But even the pi 3 overclocked seems to crash and theres a lot of freezing.

you must have some other issue, probably either not enough power, or an aggressive overclock. this shouldn't cause crashes or freezes or anything like that.

ok so i got a new power source it did not solve the problem.
But I have worked out why It has been freezing. It was the SD card !! **
So basically I took a different type of sd card from san disk and there you go.

Now the weird thing is, when i go into the retroarch.cfg settings to put the neon enhancements on theres nothing in the cfg file. only this

Settings made here will only override settings in the global retroarch.cfg if$

input_remapping_directory = "/opt/retropie/configs/psx/"

#include "/opt/retropie/configs/all/retroarch.cfg"

that's the wrong file. see the original post or docs. https://github.com/retropie/retropie-setup/wiki/Playstation-1#enhanced-graphics

Ok so really strange situation,
Reinstalled retropie, did not put the bios in. PS1 game works fine. no freezes.
As soon as i copy over the SCHP001.bin into bios and enhance the gfx it starts freezing and crashing.

pcsx_rearmed_neon_enhancement_enable = "disabled"
pcsx_rearmed_neon_enhancement_no_main = "enabled"

If I have them like this, I have no crashes anymore or freezes, but the quality has dropped.

I tried overclocking the gfx, that didint help. I can actually hear the sound struggling when I put the enhancement on, as if the cpu isnt good enough.

sorry, misread. trying again:

bios should be in uppercase, and be called SCPH1001.BIN. crashes are probably due to the issues i mentioned previously: https://retropie.org.uk/forum/post/68747

pcsx_rearmed_neon_enhancement_enable = "disabled"
pcsx_rearmed_neon_enhancement_no_main = "enabled"

that's a pointless setting as you've disabled the enhancement, but enabled the speed hack for the enhancement. i don't even know what that would do.. probably nothing.

overclocking GPU is pointless as pcsx is done purely on the the CPU. you're just adding more instability. i think your CPU is downclocking due to overheating, overclock or power - the same things that likely causing pi to crash it to crash.

I have heatsinks on every chip and a fan blowing on them plus an LCD display with temp monitor.
running between 36 and 46 degrees max. So its not that.

the bios upper case? when i go into the \RETROPIE folder the bios file is like this SCPH1001.bin isnt that uppercase?

I will now try and only overclock the cpu... cannot understand this is not working for me and working for others.

PSU ?

no - .bin is lowercase

isn't what? an overclock doesn't have to be hot to be unstable. it just has to be overclocked. remove all overclocks if you have any instability.

ok so the psu is the official raspberry pi 3 one. 2.5a with 5.1v.
ordered it before yesterday thought it was that. But it helps anyway with powering controllers the 2.5a 5.0v wasnt good enough i had the bolt from time to time.

The .BIN is correctly in uppercase.

dre3ed

So I removed the overclock, it plays but then I can hear the sound starting to struggle and slow downs in the games. I will try a cpu overclock now. I'm running out of ideas.

dre3ed

just for info my config.txt looks like this by default without me doing anything. Anybody see anything wrong ?

For more options and information see

Some settings may impact device functionality. See link above for details

uncomment if you get no picture on HDMI for a default "safe" mode

#hdmi_safe=1

uncomment this if your display has a black border of unused pixels visible

and your display can output without overscan

disable_overscan=1

uncomment the following to adjust overscan. Use positive numbers if console

goes off screen, and negative if there is too much border

#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

uncomment to force a console size. By default it will be display's size minus

overscan.

#framebuffer_width=1280
#framebuffer_height=720

uncomment if hdmi display is not detected and composite is being output

#hdmi_force_hotplug=1

uncomment to force a specific HDMI mode (this will force VGA)

#hdmi_group=1
#hdmi_mode=1

uncomment to force a HDMI mode rather than DVI. This can make audio work in

DMT (computer monitor) modes

#hdmi_drive=2

uncomment to increase signal to HDMI, if you have interference, blanking, or

no display

#config_hdmi_boost=4

uncomment for composite PAL

#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

Uncomment some or all of these to enable the optional hardware interfaces

#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

Uncomment this to enable the lirc-rpi module

#dtoverlay=lirc-rpi

Additional overlays and parameters are documented /boot/overlays/README

Enable audio (loads snd_bcm2835)

dtparam=audio=on
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=256
overscan_scale=1
dtparam=i2c_arm=1

@dre3ed please put configs in a code block or use external pastebin site. Click compose button for help in editor.

dre3ed

sorry!
I will in futur do that, my bad!
¨
Ok so I tried overclocking to 1300mghz, a bit faster game play but crash after a bit temps are still 44.., at 1372mghz overclock pretty good game play but still some slow downs then crash

@dre3ed Please can you edit your post and do it, so it's readable.

Have you made sure your lr-pcsx-rearmed is up to date? Please can you post your complete retroarch-core-options.cfg and /opt/retropie/configs/all/retroarch.cfg file.

Please disable all overclocking for testing/debugging of any emulator issues.
