Had anyone tried these before? The LCD with audio board option on AliExpress?

€ 20,82 13%OFF | 9.7"inch 1024*768 HD screen display 4:3 LCD Controller LP097X02 LTN097XL01 monitor driver board HDMI VGA 2AV for Raspberry Pi

https://s.click.aliexpress.com/e/AjrY3Mz

Would be fairly cheap, good quality and the right aspect ratio (or close at least)

I'm a bit hesitant to buy one so I was wondering if there's some that has experience with this one.

Or maybe someone has better option? I want to build a small arcade system.

Thanks for any help

I've not used that particular board and/or screen before, but I have ordered a similar configuration from aliexpress before (although I bought a much lower priced and lower resolution allwinner screen) and their service was absolutely fantastic. despite it taking nearly 2 weeks to arrive I got full tracking and I'd say in that sense it was better than ordering from the UK since you knew exactly where the item was at all times. It was well packaged and I was up and running within minutes of receiving my parcel (although I did have to make some changes to my config file before it would boot, due to the strange resolution I had to set it to). I'm dubious about it saying HD but then saying VGA in the same description. I didn't know ipad screen resolutions were so low and 4:3? But you know all said and done it's gonna be a great quality screen for what you need as most games run at that aspect ratio and for the price you're normally looking at double that for a decent screen, plus you get the driver board too so it should work straight out of the box.

@mitu It works now. Thanks alot!

@mitu Thank you for such an informative reply! Very much appreciated :)

@BJRetro Yes everything works good! Thanks for the extra info on Naomi/Atomisware!!!
Guilty Gear X 1.5 and Fist of the North Star works great.

@rodney007xx said in Help for new user please, retro pie issues on 3b+:

@simpleethat > My friend said that his interface of retro PI looked nicer, perhps its because he is using a pre-made image with a different skin?

You can install many so-called "themes" for Retropie. See the Docs about how to install them, and for a list of many (all?) of the themes with screenshots.

Welcome to the Retropie community. Have fun. :)

Huh. Now that's weird.

I tried what you described (thank you very much for that!), and while the script works like a charm, for some reason fbi fails to load the 1920x1200 splashscreen. It literally returns a black screen with

/home/pi/RetroPie/splashscreens/retropie-extra/rookervik-pixel-16x10.png: loading FAILED

written at the bottom. The weirdest thing is that if I run

sudo fbi -T 2 -once -t 20 -noverbose -a -l /etc/splashscreen.list >/dev/null 2>&1

after start up, mimicking the syntax in /opt/retropie/supplementary/splashscreen/asplashscreen.sh, the image is shown normally!

So close, yet so far! Any ideas?

EDIT: UN-FREAKING-BELIEVABLE! That was happening because I’m using USB auto-mount for loading roms into the system. For some reason, that option also overwrites the splash screens directory, but the pendrive is only mounted AFTER the splash screen is actually shown on startup. Hence, when I moved the stretched image into the directory, I was actually moving into the pendrive, which is ignored by the Pi on startup! All I had to do was unmount the pendrive, copy the file into the SD card and it worked! 😁 Thank you very much once again for all the help!

@jthomas5150 If you press F4 in emulationstation then you can quickly find out how your keyboard is configured (by trial and error). For example on my big keyboard almost none of the symbols on my keyboard coincide with the symbols that appear on my tv screen when I press them.

@SpudsMcToole @mitu

I was able to run Casio PV-1000 using lr-mess. It took me 36 hours to compile lr-mess on my Raspberry Pi 3b (stretch) with the original power supply, a swap of 2gb and a gpio CPU fan.
After the compilation a hash folder is created in /home/pi/RetroPie/BIOS/mame/hash. The file pv1000.xml contains the description of the roms with the valid sha1 hashes. You can check if your rom has the same hash with "sha1sum <yourrom.bin>". If it's the same, you have to zip it.
The name of the zip file should be the "software name" which is defined in the pv1000.xml. And the bin file name inside should be the "rom name" which is defined in the pv1000.xml

So for your rom the zipfile should be "tutankhm.zip" but the file inside should be "tutnkham.bin"

<software name="tutankhm"> <description>Tutankham</description> <year>1982</year> <publisher>Casio</publisher> <info name="serial" value="GPA-103"/> <info name="alt_title" value="ツターンカーム"/> <part name="cart" interface="pv1000_cart"> <dataarea name="rom" size="8192"> <rom name="tutnkham.bin" size="8192" crc="a0b606d8" sha1="56efa2ab7c4a6db7b44714e46c5bf2ba71983ee8" offset="0000" /> </dataarea> </part> </software>

@mitu Thank you so much. This solved my problem. I never knew there was such trouble just copying files. And thanks again for the advice, copying over wifi and ssh 10.000 small files is really a bad idea.
:)

@jerryfudd It's a raspi-config configuration error. Modify the
/etc/systemd/system/getty@tty1.service.d/autologin.conf
file and replace its contents with

[Service] ExecStart= ExecStart=-/sbin/agetty --autologin pi --noclear %I $TERM

then restart your system.

@The16BitGuy Please post the full error message and the step in the installation where you get it. What version of Ubuntu are you using ?

@ivooc
Yeah I meant threaded video. I've had the same RetroPie build from version 4.4, its hard to remember all the changes and configurations I've made. I'll try to share once I think of them.
Do you have a fan installed? The temp_soft_limit is 60 by default and will throttle the cpu to 1.2ghz
I increased the soft_limit to 70 and it barely reaches 63 during emulation.

Have you updated retroarch, raspbian, and your cores, since you installed the image?
the firmware, I should search to find out for sure, I think it is updated when you go to retropie config >> configure >> raspbian >> update raspbian(next to install pixel desktop)
It could be a psx_bios, some have higher compatibility, I have quite a few in my folder actually, but I think scph_101 is the highest compatibility and it will be chosen over the others, not to be confused with scph_1001.

As I say that Gran Turismo refuses to work.
I don't know why, but I did update the core since I last played it.

Please can you have the crc32 for level2.rom of the trs-80?
In the doc file the link for download is old. Error 404.
If can give me all crc32 for all bios?
Thank you very much.
Sorry for my bad english.

@mitu alright, you can delete this thread, I'm not really sure how. Appreciate the responses

@Efriim It is possible if you feed it some outlandish timings. I am not saying the ones you have posted will do that, they may well work OK, but not knowing the source and what they were intended for it's hard to say. I'm talking about the hdmi_timings ones, these can be dangerous. The config.txt is good, but I would skip the ones from your post starting with hdmi_cvt.

I'm bit busy now but will post my confirmed-working settings (for a CRT TV though) later. In any case OP should try the arcade forge image first, even if just to copy the configs from it to the official Retropie.

EDIT: my old config.tx. You can also try the "AF" and "mohl" settings (just make sure to remove #AF for example)

gpu_mem_256=128 gpu_mem_512=256 gpu_mem_1024=256 disable_overscan=1 disable_audio_dither=1 dtparam=audio=on dtoverlay=vga666 enable_dpi_lcd=1 display_default_lcd=1 dpi_group=2 dpi_mode=87 hdmi_timings=320 1 15 20 49 240 1 6 8 10 0 0 0 60 0 6400000 1 #c64hdmi_timings=336 1 10 18 46 288 1 5 6 6 0 0 0 50 0 6400000 1 #AF hdmi_timings=320 1 16 30 34 240 1 2 3 22 0 0 0 60 0 6400000 1 #mohl hdmi_timings=320 1 10 20 54 240 1 6 8 10 0 0 0 60 0 6400000 1

This should give you a stable picture, I have used these settings on many CRT TV sets, they should work on a monitor too I think (or at least won't damage it).
problem is, this will only work for few emus in 1:1 scale, since they often used different resolutions. To handle this you need to use the high-res trick (read the thread I linked to)

For that you need to change the runcommand and then also adjust the settings in retroarch.cfg (custome aspect ratio and resolutions, or use integer ON/Off option). Unfortunately I'm not near my SCART TV sets and can't remember all these settings exactly so can't help you here. You either use the Arcade Forge image, figure it out from the resources here or post on reddit in /r crtgaming sub.

My runcommand-onstart

fbset -depth 8 && fbset -depth 16 -xres 1920 -yres 240

My runcommand-onend

fbset -depth 8 && fbset -depth 16 -xres 320 -yres 240

You don't seem to run RetroPie, so why post here in the forums ? You can find the list of resolutions you can add in config.txt here.

@fomt No, keep the other steps, just don't run the passwd -d <yourusername> step.

@Littlezero .srm and .state files are not ROMs, as you have discovered.

@marcoabm there is a way to do this so that someone has to press the back button (usually coded as B) to get out of the favorites list. I BELIEVE though I am not in front of my pi right now that if while in emulation station you hit the start key to get to the emulation station menu you have to change two options (btw I have this set up on my bartop this way for the reason you mention). First there is an option for start on system or something similar and you can choose “favorites”. This way when the pi boot it will go right to
Favorites. Then there is another option. It might be called quick system select or quick carousel or something. You can disable that and now someone can not switch systems by moving left and right they have to press the button to physically back out of the favorites menu and back to the top menu. I will try to find the exact name of the option later if you can’t find it.

EDIT: Ah! I found it online. It is in the emulation station menu as UI options, then “quick system select” you want to disable that. Also, if you want to go super extreme and don’t want to leave it as just difficult to go to the other systems but rather make it absolutely impossible to do that; you do the foregoing two steps and then also edit the configuration file that is related to the actual control buttons for emulation station and remove the back button. I am not a big fan of that personally because I still like to be able to back out sometimes but if you really want to do that I have done something similar (switched the button used for menu and back in emulation station) so could walk you through it.
