Uh dang, I need to make some retractions here.

I went back to re-examine the joystick circuitry and stuff and it looks like the thumbstick works fine at any voltage. (I felt my logic was odd when lying in bed the other day). The "lopsided-ness" I was talking about is actually caused by setting the range incorrectly. Ignore what I said for #1 in the previous post. The thumbstick appears to behave the same with 1.8V as with 5V (from a design standpoint, you'll probably save a little power by driving it at 1.8V).

Most modern joysticks expect something in the range of -32767 to +32767 with the center/neutral point (when the joystick is not being touched) being 0. Why? Because this is the min and max values you can represent with a signed 16 bit integer. To be extremely pedantic, you can actually go to -32768, but we pretend it's -32767 to make it symmetric.

When I did the mapping function, I take an input range of values going from ~70 to ~325 to 0 <-> 16384. I think this is where the "lopsided-ness" comes in. I'm using a built in function from the Arduino library called map() so I don't exactly know what is going on, but it places the center point somewhere around 4000 instead of ~8150 as you would expect. This isn't a problem if the output range is -32767 to 32767 for some reason.

@dankcushions

ok i did that, i hope it fixes it

@crossmr Turns out I had the wrong image, after hours of slow downloads, I managed to get the same pi zero w image that I had before. it looks like the rom in question was being run on lr-fbalpha, not fbalpha2012. This was a retropie 4.2 image. The performance on lrfbalpha seems slightly better than the alpha2012 that is available on 4.6 retropie but still not as good as pifba.

@crossmr I managed to get the controls reconfigured, however the graphics option"MaintainAspectRatio=1" doesn't seem to work in the config file. Right now the image is stretched to the sides, instead of maintaining the proper aspect ratio.

@mitu
I do have 4 usb joysticks modules attached. Maybe I have a hot key setup by mistake.

Thank you, gives me a whole bunch of new stuff to try tomorrow morning, see if I can get it working.

@redfirebrooks said in Cant set resolution.. Really it is that easy ?:

i'd like to find a working out of box retrogaming system !

Well, RetroPie isn't meant to be one in every case and aspect. It's an community-driven, freely given DIY project.

That said, RP works ootb in many if not most cases. But if you happen to be one of the unlucky exceptions, you'll have to either put some time and effort into it, or move on to another system in the hope that that one won't have the same problems with your setup.

You're free to choose whatever suits your needs best, but complaining about it in every of your posts in this thread so far distracts you and everyone else who are willing to invest their spare time for your problems from actually working on a solution.

Just to note I have just improved the Kodi module as it failed on Ubuntu 20.10 - it should help with other Ubuntu versions (Basically it checks which kodi packages are available due to packaging differences between PPAs/versions)

@mitu said in Joysticks not detected after upde:

it's your device - did you purchase it with RetroPie ?

Not really, it's not my device. My sister gave it to me because they were not using it and after updating it the joysticks stopped working.
I will try to reinstall mk_arcade_joystick_rpi and if not, I will have to reinstall it from 0.

Thanks!

@quicksilver Awesome job on the fairly grueling calibration of Hard Drivin. Can you, by chance..please share your nvram for this or any other similarly minded games! That would be absolutely awesome! I am hoping to do as many of the more complicated Racing Game calibrations, as feasibly possible. And, these calibrations, we can make permanent, code wise, too! That way, noone will have to calibrate them in future revisions of our MAME code base:) Already have many done, such as Carnevil, Terminator 2, Revolution X, etc, etc.

@dankcushions I cannot do that now but may you please look at my other post

Thank You!

Hey @mitu thanks for getting back to me. It turns out the issue was not the wifi connection. I'll explain for anyone who might run into this stupid problem as well:

I'm working on a Mac (booooo) and when I opened the wifikeyfile.txt it opened by default in TextEdit.app. When I opened it and entered my credentials it looked a bit like this:

ssid="wifinetworkname"
psk="mypassword"

Unbeknownst to me, a non coder, it turns out there are two different types of quotation marks. WTF, right? See if you notice the difference between the two below.

Yeah, unsurprisingly if you have quotation marks like those on the left like I did, when you try to <import wifi credentials boot/wifikeyfile.txt> it won't be able to read the text correctly.

The fix?
Go to the toolbar under edit > substitutions > smart quotes. Uncheck that option and you'll be able to type no nonsense vertical quotation marks that RetroPie will recognize.

Alternatively, if you open your wifikeyfile.txt in Sublime 2 instead you shouldn't have this bs problem. Seriously, I don't need fancy quotation marks here! I'm not writing a novel and if I was I wouldn't be using TextEdit.

Make sure you don't have a return below your second line. It'll be invisible if you don't have your text cursor on it so delete space until you only have two lines.

Sorry for the text dump but I figured this may save newbie like me a headache if they try making their own Gameboy Null 2 and run into the same issues.

To answer your question about the old version of RetroPie, it was part of a pre-made image that was recommended for the project, likely to save me the trouble of button config etc.

@stefano-sudati said in can't find Steven Selph's Scraper and with Lars Muldjord's Skyscraper no video:

Reading the forums I saw that the videos need to be converted to make them work but I still don't understand how.

There are at least two scripts to convert incompatible videos:

mine (simple, but does its job) hiulit's (has more options)

@xxalphawolf420xx From the 2nd screenshot, I see that the WLAN Country hasn't been set. It shows as DFS-UNSET, while on a working system it should show:

root@pie4:/home/pi# iw reg get global country UK: DFS-ETSI (5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS, AUTO-BW (5490 - 5710 @ 160), (N/A, 27), (0 ms), DFS (57000 - 66000 @ 2160), (N/A, 40), (N/A)

The other command screenshot looks like the command's been miss-typed (wlan instead of wlan0).
Check again your wpa_supplicant.conf and make sure it's correct - no extraneous characters, proper newlines, no funny quotes, un-balanced parantheses {/}. Post it here to take a look.

@tpr Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

Please start a new topic providing details of set up and which emulator you are using - there are multiple scummvm packages in RetroPie.

@mitu Yeah, I am sorry... I did something that required it, and then neglected to change it back. Poor form.

@magikarp1232 today i get the third badge(im playing the yellow version in my raspberry),i like the game,the moves effect and i considerer the game a little hard...the moves don't hit much and pokemons don't give you much exp neither,you can get TMs random drop from trainers or wilds pokemons(i really enjoy that,they have low chance )...for now i enjoy the game
