Unbelievable! THIS is how it should have been done from the start!

I've moved ALL configs over to the usb drive now and it easily shaves 8 secs off of boot time. The 4 raspberries screen used to sit longer. Now they are gone within 4-5 secs before loading my custom animation movie (which is still on the microsd). But everything else is on the usb drive now

I mounted dev/sda1 to /media/usb0 as I only plan on having a single usb flash drive in the system. I replaced the following directories with symlinks: /opt/retropie/configs to /home/pi/RetroPie/configs /etc/emulationstation to /home/pi/RetroPie/etc/emulationstation /home/pi/RetroPie to /media/usb0

As there are some symlinks within those folders, I simply renamed to the one I use. So for example in the download_images folder, "genesis" was symlinked to "megadrive", So I just removed genesis as all my roms use megadrive folder structures.

Now I can edit config files by simply inserting the usb drive into my windows computer and editing them, then simply pop the usb back in to see the changes. Plus I have all the theme settings, scraped images, etc all on the faster drive (usb much faster than microsd) so things like all the game images load much faster.

This leaves the microsd all but isolated to do just the core system work. I used to load my custom startup movie from USB too, but found that during startup, a lot of times the usb drive isn't ready yet so the video only played 30% of the time. Moving it to the microsd allowed it to be ready to go and plays everytime now.

I would definitely recommend doing this for power users but really I would recommend this for new users too as it is much easier to wrap your head around things when the data is all in one location.

I have not yet tried the readonly script, but I was more concerned about this part working first and it works even better than hoped! Long live the symlink!

@Exmix Looks like a waveshare 3.5 tft spi
@obsidianspider did a kind of How-To in this thread so congrats to him for keeping all links in one posting.
Be carefull the 3.2" TFT uses annother resolution (and other overlays??) than your 3.5"

@mat03111984 said in emulation in shops:

such a shame that there not a place where people can relive them for free

Weeelll, when you put it like that, I am reminded of an exception, should you happen to live in the United States. A certain website was granted exemption from the United States Digital Millennium Copyright Act and is allowed to possess and even cache games to be played directly from a browser. You can also download games and even whole collections of games without worry of violating copy protection, so long as you don't redistribute the games, or make them available for public play afterward.

So, as it currently stands, if your business resides in the US and you offered up the ability to play the games via their web-based cache format, I don't believe any laws would be broken at all. This would effectively allow a makeshift internet arcade to exist where people could gather to relive these games for free, legally. What's more is that when Kodi v18 is released with their RetroPlayer media layer, an addon will also be available to stream and scrape these games from the website, allowing an almost unlimited game library to be searched, browsed and played as if they all existed on your system without the need to take up any significant local storage space.

All in all, it really is a great time to be a retro-gamer.

ok, thanks

you don't need to do any tweaks or changes from default to get nes/snes running at fullspeed. in fact, i would revert all as you may have created a problem if you solved your power issues.

audio distortion/sluggishness - we need specific examples. many nes games had audio distortion/sluggishness on the original hardware, which will be the same when it's emulated.

@buzz said in CRT-Pi Shader differs on Pi Zero vs. Pi 3?:

@riverstorm I set render resolution to default (video res) and video res to 720p. So they are both 720p. Looks good to me on my screen.

Thanks Buzz this worked perfect and runs the older games listed above just fine. In either 720 or 1080 with both Udb's overlays on and crt-pi shader enabled. Stock is a bit--bit sluggish at 1080 but is completely playable. Overclocked is no problem. I did not have FPS up but just more going off feel.

I also tried Udb's overlays. The 1080 overlay worked in both 720 and 1080 and fit perfect. I am guessing it's just downscaled in 720. You need to set both the group and mode to get the output set to 720. Just the mode doesn't work.

I also did not know the difference between video and output settings in the quick config as they seem like they should be the same logically thinking but video is the one to choose.

One thing that was off and didn't work correctly was Dank's custom shader configs. I used a stock 4.3 image and updated the script, retroarch core and lr-mame2003. When I ran a game it would just show me the top left corner of the game like it was really zoomed in. I am not sure if it was something as simple as a setting to get them working again.

I did get a modest overclock on the arm but decent on the gpu & sdram. The arm_freq up to 1075 (7% increase), gpu_freq (which includes the core_freq & v3d_freq) up to 525 (24% increase) and the sdram_freq up to 525 (24% increase) also.

The arm_freq is a bit modest. It is the same SoC as the Pi 1 but the manufacturing technique improved in the 4 years between releases and they were able to release it as 1,000 MHz stable whereas the Pi 1 was released as 700 MHz stable at the time. I would guess it's really pushed to it's limits already at 1000 but I see some that are getting good silicone at the top of the bell curve of variance are getting 1.2 GHz.

It's already overvolted to 6 but a simple small heatsink barely protruding through an acrylic case kept mine more than cool enough with nothing special.

A good base starting point is 1000 for arm and 500 for gpu & sdram and I worked up from there.

I did get some annoying static-ish feedback noise in Elevator Action but games like Rastan, old classics, etc. worked great.

For shaders 480 looks muddy (I prefer the solid jaggy graphics over this), 720 is acceptable but at 1080 you can clearly see a difference on a 4k TV and looks great. It might come down to performance when choosing which resolution and if using overlays and shaders.

I do like the zero but it seems like a niche market for handhelds or some special project. It's sluggish in everything from bootup, loading games, etc. compared to the 3. I think if you have room the 3 is the way to go but the zero is nice and incredibly small. Easy to velcro to the back of the TV or something. Using thin HDMI and power cables would make it easy to hide as it's quite a bit smaller then the 3 with a case.

I would recommend renaming the file: I tent to append .bak to the end (so default.cfg.bak). Deleting the config mean a new one will be generated with default settings, but if you made any customer mappings, you may need the current file to reference.

@Wizardling Glad I could help. That 5V fan should keep things nice and stable at 1300 MHz. I do not recommend overclocking the CPU at all without active cooling, but sounds like you have that covered. Best of luck to you in your experimentation friend.

@meleu Tried to replicate the issue one more time and now its working fine.

bangs head against desk

Thanks for the info. Can't wait for my Pi 3 to arrive!

Is the Wii U Pro Controller any good with RetroPie and N64 games?

No measurable performance increase from my testing. If you build from source you will get rpi3 optimised binaries.

@backstander
Oh yes - I answered with a Rom because he askeds for downloading Roms. The games you named are also good examples. I misunderstood something.

@mediamogul
Nice gameplay - thank you
You can download RecalBox and extract the Roms folder there are also some homebrews located

@gazum123 Glad I could help. The High-Resolution mode does incur some minor graphical glitches in some games, but the visual improvement is very obvious and I believe it is a necessity for a high-def TV, especially since the default resolution has this grainy effect which I find distasteful. I believe that all graphical calculations (geometry, texture mapping, etc) for PS1 emulation are done exclusively through software with little to no help from the GPU. As a result PS1 emulation carries a high CPU usage compared to most other emulators (especially in high-res mode) and gamers couldn't enjoy the high res mode in a lot of games until the Pi3. The Pi3 seems to be able to handle it without fully utilizing an ARM core however so I highly recommend it.

I've created stressberry to create standardized temperature signatures; hopefully we'll be able to properly compare all solutions with it. I'm hoping to be able to add a few more graphs in the coming weeks. Perhaps other people would like to run stressberry as well.

@Kristopherson05 Thanks, it worked. Don't know what I was doing before. Didn't need ip address though, just retropie, pi and raspberry.

Thanks

Kev

@agour Have you ruled out the adapter at all? Does it work fine on a PC? Also, are you using a Libretro based emulator, as the retroarch configs only apply to them.

Thanks for the tip. I tried this, but it didn't seem to help.

Could booting to Kodi contribute to this issue?
