If you use a Euro (PAL) rom on a US (NTSC) machine, the game will run fast.
If you use a US (NTSC) rom on a Euro (PAL) machine, it will run slow.

So, if you are in the US running RetroPie on a US TV, you should not use a European rom. You can switch the Pi into PAL mode (if you have a TV that can tolerate it) and it will run at normal speed, but I wouldn't recommend it if you can just get the US version instead.

hdmi_safe will set the resolution to 640x480, if your monitor supports a higher resolution, you can set it by using hdmi_group=2 and hdmi_mode set to one of the values detailed in https://www.raspberrypi.org/documentation/configuration/config-txt/video.md. You'll probably have to add hdmi_ignore_edid=0xa5000080, my guess is that your monitor supplies a wrong EDID and the Pi tries to set the video resolution to an unsupported value.

This issue is now fixed as of 8-24-2020. Update from source if you experience this issue.

@jbsapp Unfortunately, no. I stopped searching for a solution after awhile, since it doesn't bother me that much. Actually, I came to appreciate that the beautiful Comic Book Theme is shown from time to time this way.

A friend of mine who is an electrician suggested to short-circuit the port in question by sticking a piece of wire in both sockets. I never got around to do this unbelievably complicated operation, though. 😇

@VictimRLSH

Thank you .. Glad to know a 2gb is what i need for gaming since i have no use for the desktop feature at the moment

@BuZz Thanks Buzz! I have now set it up to boot directly into Retropie. No issues so far.

Hey, thanks all. I changed this around as suggested and it worked.

Button 5 is real block and 6 is "quick block".

@amurphy9495 probably similar to https://retropie.org.uk/forum/topic/27559/. Please add some info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

You press Start to open the EmulationStation menu. How exactly did you de-activated the on-screen help or switched themes ?

@muppets4 said in MAME: how to prevent vertical games from going vertical?:

CRTPi-RGBv30

sorry, but we do not support third party images.

Yes

From less than 1 kilobyte to over 1 Gigabytes

I started with a 32GB which is plenty for Arcade Games ... as soon as you add consoles, well, i got a 64GB card which lasted a month before i got a RPI4 and was able to add even More Consoles .. picked up a 128GB card. Will see how long that lasts ;) ... prob end up using a hard drive for game next and just use a smaller SD Card for the Retropie OS

TLDR: SD Card Size will Depend on what systems/consoles you intend on playing.

Oh, and if you compress you roms/images (ie. i have compressed all my PS1 games to PBP format and Dreamcast/3DO/Sega Saturn games to CHD format ... saves a TON of space !)

Yeah, should be fine .. all my cards a Sandisk

SUCCESS - it looks like I've fixed it. The problem was that I hadn't commented out the unused buttons in the "Input device" buttons section of retroarch.cfg. Before I updated RetroArch didn't care, now it obviously does.

So I rolled back, updated and then only made that change to the retroarch.cfg. Everything else still works as before, because I didn't need to reset EmulationStation or MAME cfg files.

In the end it was a simple fix, thanks to everyone for all their feedback which helped me find the solution. Hopefully this thread helps someone else down the track.

@mitu I see... thanks for the info!

Truth be told, I prefer the old text notifications anyway, so I'll be turning off the widgets posthaste.

@mitu ok. thanks.
i guess i will have to start from the scratch.

@Geneintheuk It was a spam bot.

Thanks everyone.

MK2 indeed worked better in lr-mame2010. Not quite as smooth as 2003 or 2016 with sound sync off (only noticable on the scrolling "tree" fighter lineup and the "insert coin to continue" slide-in... actual gameplay is great).

NBA Jam TE worked perfect in 2010.

@gmesmer no it's not.
