@kouen922 looks like SD card corruption. Might be worth testing out another micro SD card just to be sure.

Also we can't read minds, if you want to narrow down your issue you need to explicitly detail your setup steps etc detailed in https://retropie.org.uk/forum/topic/3/read-this-first

Easiest way I've found is to just take it one step at a time documenting each step to narrow down where exactly things go wrong

I'm a big fan of the arcade folder. I like keeping everything in one area

@obsidianspider well if you think about it you're using a computer... To emulate a computer... To emulate another computer ;) emulatorception! lots of overhead processing there. But glad it's at least functional :)

Sorry to drag up an old thread but is the fixed N64 rendering resolution of 320x240 the reason the games look terrible?

I posted this over on Reddit, but basically I have a new Raspberry Pi B 3, I've done a fresh download & install of Retropie 4.1, placed the ROM's in the N64 directory and if I use the gles2rice or GLideN64 video plugins it's VERY block & low resolution.

Interestingly if I use the glesN64 video plugin for Mario Kart or Super Mario 64 they both look incredible, very crisp as if they're being rendered at 1080p. Unfortunately these are the only games this works for, Zelda OoT for example looks as bad on this plugin as it does the others.

Sorry if I've missed an obvious setting? Here's the thread over at Reddit if it helps. How can I render some games at a higher resolution? I don't expect to run OoT at 1080p but if I could wind it up a little that'd be nice, on my 75" TV it's a mess.

i would use our guide instead (which is pretty similar, but has some crucial extras) - https://github.com/RetroPie/RetroPie-Setup/wiki/Running-ROMs-from-a-USB-drive

@SlowSL You can try creating a .bat (batch) file using the following command, and then editing it with notepad and replacing all instaces of .zip with .mp4 or any other extension.

for /f "usebackq delims=|" %f in (`dir /b "c:\MY_1000_HANDPICKED_ROMS"`) do echo copy "c:\NEW_FULL_NONMERGED_SET\%f" "c:\NEW_1000_NONMERGED_ROMS" >> C:\EXAMPLE.BAT

That's a bit hokey, but I'm not as familiar with DOS scripting. If you were doing something in the linux environment, you can use string substitution in bash fairly easily. For example;

cd /home/pi/RetroPie/roms/mame-libretro for f in *.zip; do cp /path/to/mp4s/"${f%.*}".mp4 /somewhere/else; done

In the above, the .zip would be stripped from the file name, and it would be replaced with .mp4

@overlord73978 Your romset (game zip file) is not compatible with the emulator you are using. Most commonly this is because the the romset version does not match that required by the emulator. More details on what to do on your other thread but it's basically:
https://retropie.org.uk/forum/topic/2859/how-to-use-mame-with-retropie-help-guide

@overlord73978 You should have downloaded a complete set of roms that is labelled accordingly. For Mame4All you need roms from the 0.37b5 set. I am guessing that because you don't know, you just downloaded a few random roms and tried to launch them in a mame emulator? A common mistake and the path to great frustration. MAME requires patience and an accurate set of roms that match the emulator of your choice. You can verify the roms you have using clrmamepro. The best way to use MAME in an "enjoyable" way currently is to first choose an emulator - lr-mame2003 - then find a set of roms that is compatible with it, i.e. the 0.78 romset. Before proceeding, you should read this very carefully as it will demolish any confusion you may have......
