Assuming that the upgrade process won't take more space than the size of the base installation itself (e.g. if the base install is 3GB, the compressed packages for upgrading won't be 3GB themselves), and assuming that the increase in the size (post upgrade process) wouldn't be nearly that much... I'd say 4+ GB free is a nice safe amount (and probably overkill).

Given the price of USB flash and microSD cards, I'd whole-heartedly recommend paying some $10 in exchange for quintuple the space and not having to worry about this. I'm particularly partial to Sandisk Ultra Fit drives, solely because they're the size of a wireless keyboard dongle and cheap.

Boosted the signal to 8 and I got an image but it was very fuzzy and looked like it was using less colours. So I then tried to boost it to 5,6,7 and got no image

Will buy a new HDMI cable when I am on my travels today but find it unlikely to be the cable itself as once upon a time the cable I am using now did provide an image via the AV receiver.

I removed all the duplicates and still this does not work.

The odd thing is that I seem to have a retroarch.cfg file appear in the libretro-Mame folder which does not look like my setup, its like a bunch of random keys. I will paste this in this evening when I am back at home.

First search hit man. https://retropie.org.uk/forum/topic/3510/dreamcast-rom-folder-missing

AHA! Think I've fixed it.

Find the gamelist .xml file for psx, delete it, then rescrape the game data.

Hi @xxghostbusterxx

In my previous experience, a WSOD (white screen of death) in Emulation Station is caused by too low a GPU Memory. You didn't specify which guide you followed, is there a chance that you changed this when trying to overclock the pi?

If you exit to the prompt by pressing F4 (even in a WSOD) and run:

sudo nano /boot/config.txt

modify the gpu_mem line to:

gpu_mem= 256

Then press Ctrl+X, Y (to save the file)

then type:

sudo shutdown -r -t 0 now

This should reboot the pie. If you still get a White Screen of Death, try changing to a different theme in emulationstation (press start on the controller, the menu will still appear).

@omev2

Here's a thread we talked about the PS3 controller and Reicast
https://retropie.org.uk/forum/topic/3120/problems-with-dreamcast-and-ps3-wired-controller

@Ristul Could you post your retroarch.cfg file here?

@MrChilliBeer I'd try this one:
https://github.com/retropie/retropie-setup/wiki/scraper

That worked for the Genesis/Megadrive, thing is I can't exit a game from the gamepad I have to use the Esc key, any ideas?

Thanks

Do you bother with any of these?

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

Just a quick follow up on this issue, I successfully ran puyo puyo with mame2003 and the right romset.
Thank you for your help Floob.

@Floob Thanks. I'll check it out.

@suprjami said in Installed 4.0 retropie...now no shutdown..:

@chippettone The X360 L2R2 configuration problem you describe is resolved in 4.0 with an xpad module option that changes the analog triggers into buttons.

If you need to add the module option, this should do it: echo "options xpad triggers_to_buttons=1" >> /etc/modprobe.d/xpad.conf and you'll need to reboot then reconfigure controllers after that.

This is set up by the xpad driver in RetroPie-Setup, but it will have no effect unless that driver is installed (the option may exist for the shipped kernel xpad driver, but it will only apply to unknown joypads. I patched the updated xpad driver to make this apply for any joypads).

If the user has updated from 4.0rc to 4.0 final, they will need to install the new driver from Manage Packages -> Drivers -> Updated Xpad Driver

I'll get back to my forum break again now :) - just wanted to clarify this in case the OP hasn't installed the updated driver (which it looks like).
