Most games are fine...HOWEVER. Some of my absolute FAVORITE games (Penguin Brothers and Daisu Kiss for example) don't work. For the sake of this post I'm just going to talk about Penguin Brothers and Daisu Kiss.

Daisu Kiss: So, it loads perfectly, that's for sure. However, when I get to the ROM check (It says Ver: JAA in the corner) it does nothing. The ROM check clears away so I only have a black screen with Ver: JAA in the corner. I watched four episodes of Gravity Falls waiting for it to work (That's two hours!) and I check back,  nothing. It still says Emulator Loaded, even with the clearing of the ROM check. Does this happen to anyone else?

Penguin Brothers: It loads fine, still says Emulator Loaded, I insert nine credits in, hit one player and go for stage one. And that's when everything goes downhill. In the background of level one, a whale jumps out about twelve seconds in. When it does that, the game completely freezes up, the second of music repeating itself over and over again until I close it.

You might need to re-download them.
They worked fine for me.

Try inserting 1 coin and start. See if there is some kinda glitch caused by putting multiple coins...

How do I redownload them?

I haven't played those yet but I have noticed some glitches here and there with the 64 games. Sometimes most of them load but some I cant play and I don't know why. But I usually just close it out and reload it and it works fine with most games I have tried. But it could be my cpu as well.

And to those that say that I don't have enough space in my hard drive, I freed up about 100 GB last week.

AwesomeTrinket : I've tested both games just not to see if I could re-create your problems.

Both games seemed to load fine for me and function correctly with no issues.

Are these the only two games you are having problems with?

Do you have a slow internet connection or older computer? What are the specs of the computer you are using?

You could possibly try re-downloading the games by deleting the rom files from your vizzed directory on your hard drive and try playing them again, which will re-download the rom file to your computer.

I could write a book on the problems with my favorite games (Ghoul Panic, Magical Date, Super Pang...) but I just spared your eyes by writing two of them. As I type this, the router of the internet I'm using is in the next room, so that's not a problem. 

I'm not too good with computers, but I know I'm using a 32bit Windows 7 Toshiba laptop, which got factory wiped twice since I got it three years ago.

AwesomeTrinket : Well both of the games you wrote about in this thread are functioning correctly.

Also, I wasn't referring to the distance between your computer and the router so much as the actual speed of your internet connection. If you aren't quite sure what it might be, you can test your speed using a free testing tool online like this one - http://www.speedtest.net/

To me, just based on the limited info available to me, your problem most likely is due to the computer you are using and it having a hard time rendering the game at a frame rate that doesn't lag your computer like crazy.

What happens when you try a smaller type game, like this one? https://www.vizzed.com/play/super-mario-bros-3-nes-online-nintendo-nes-684-game

So, this is what I came up with on that test:
ping : 15ms
Download speed: 15.21 mbps
Upload speed: 6.02 mbps
I've actually managed to play some absolutely huge games before (Don't ask their names, I can't remember) perfectly before. Those games are smaller.

Jordanv78 : I think I'm in the Vizzed folder, but how do I know which ROM is the right one that I need to delete? I just get a bunch of jumbled letters for names, not stuff like "daisu-kiss" or "ghoul-panic"

AwesomeTrinket : It sounds like the issue was most likely lag from your computer having a hard time rendering the game properly. Did you try loading the game I linked in my previous reply to you? If so, what happened? If you didn't, please do.

Your internet should be fast enough, depending on the other activity on your network while trying to play as well as the reliability of your wireless connection. Just for testing sake though, you could try plugging directly into the router for faster speed and see if that helps.

The File names should be pretty self-explanatory. For example, they should resemble the name of the game itself. For example, Penguin Brothers file is penbros.zip . Sounds like you are not in the right folder.

Jordanv78 : I can't plug into router (Dad won't let me) and yeah, the game worked absolutely fine.

I think I'm in the right folder, but I can't find the right files. I'm in the Vizzed folder on my computer, so it should be right, but I see a bunch of other folders.

AwesomeTrinket : IF you don't see the file names similar to what I listed above, then you are not in the correct downloads folder within the vizzed directory.

If you are using Windows Vista or above, the directory you should be in is C:ProgramDataVizzedVizzedRgrPluginRoms
You can also remove the file from the download directory as well.

Jordanv78 : All my computer has is Program Files and Program Files(x86) I haven't tried looking in the latter yet.

AwesomeTrinket : I thought you said you were running Windows 7? If so, just type this directory into your file explorer and it will pop right up where you need to go.

C:ProgramDataVizzedVizzedRgrPluginRoms

If you are using Windows XP, then that's an entirely different directory.

Jordanv78 : I am using Windows 7. Again, my laptop got factory wiped two times and everytime we installed Windows 7.

AwesomeTrinket : That's what I figured based on your original posts. So unless you changed the directory when you installed the plugin, they should be located at the location I listed.

C:ProgramDataVizzedVizzedRgrPluginRoms - also will be found in the downloads folder if the download was originally successful.

Jordanv78 : Yep, I found it! P.S. you were right about the Penguin Brothers, it really WAS called penbros XD Are you a wizard or something?

AwesomeTrinket : lol I've been around long enough to know where to look as far as "best guesses" since I can't actually be there to see what's happening on the users end. Glad I could help!

Hopefully deleting those files both in the roms and the download folders, then trying to re-play them helps. If not, then I would assume the problem is lack of hardware power to properly render the games in a way that you can play them with.

Feel free to let me know if you have any other questions/concerns about this particular issue.

Jordanv78 : So far, I've only played Daisu Kiss and Ghoul Panic. Ghoul Panic forcefully closed again, and Daisu Kiss now says "Starting emulator" and I get to the ROM check and everything disappears.
