I'm not entirely sure if this is a "problem" per se, but I've just come to realize as screenshots are being taken;

All the NeoGeo games appear to be loading, by default, in Japanese.

NeoGeo ROMs have all their available languages in the same ROM (with only a couple of exceptions to this rule, none of which are mainstream games.). IIRC, the BIOs being used affects which language loads up by default (as well as censorship settings), although this should also be configurable in some option settings.

It might be a good idea to try to adjust this so that English is the default language loaded, considering Vizzed's common audience.

Also a nice "maybe" is to be able to play the games in console/AES mode (again, the exact same ROMs are used with one or two exceptions). Occasionally a NeoGeo game will have a little bonus only available then. It might also be a good excuse to make NeoGeo standalone, in case some features for it in particular could be implemented that wouldn't under normal MAME (I recall many specialized NeoGeo emulators have some features.)

Almost every Pokémon game says Error the Rom seems to be corrupt and my friend who is a trusted member have that problem too and I'm not a trusted member

I don't know why and/or if it's only me, but when I'm playing games, the game screen comes up and it's not centered correctly. It's centered towards the bottom right and it's happened on multiple emulators.

happy_timothy : Could you give an example or two of games that reports that? It's an easy fix, but I wouldn't know why almost all of them report that.

Dolemite : You should be able to fix that by clicking on the game page while the game window is open, then hold down the Ctrl key while pressing the 0 (zero) key, then click back on the game window.

tRIUNE : I've been trying to play Legend of Zelda - Ocarina of Time (N64) like I used to play about 8 years ago, but I can't save, use certain keys on the keyboard, or even access the key menu. I don't know if it's just my graphics card, or something with the game... I would just like to play one of my favorite games again.

Hmmmm...  I wish I had seen this earlier.  I reported  game error here in detail:

Game Error

Can you close that thread for me, and do you want me to copy paste its content here?

darkangel8xt : I can answer some of that question. Mupen64 with the RGR Plugin doesn't support customizing controls - so double clicking for the menu will do nothing. The keys problem unfortunately I don't have an answer, however, it has been a common problem for some people for at least the past year and I have just yesterday included the problem in a bug report to the RGR Plugin Developer, so hopefully it will be fixed shortly.

As for the save, try with the Mupen64 emulator with savestates. 1964 emulator doesn't support savestates but Mupen64 does.

Singelli : I have tried literally 20 different roms to fix that game but they all have the same problem - I do however know that it's fixable, I just don't know how yet. As for the other thread, I'll leave that one open because the other problem involves a broken link on the RGR page which I'll ask David about probably tomorrow.

There is one game in particular that I like to play with my friend, which isn't working.

The game is:
Yar's Revenge.

Whenever I start it, it gives me a weird screen.

RetroGameNinja : Could you post the link? The game isn't showing in search results.

Super smash bros for the n64 Isn't working. Sometimes when I click in the character select button the screen clitches. Also when I beat the first level the screen turns black.

Bug Blitz for the Commodore 64.

I'm not sure what's wrong with it, but every few seconds it glitches and turns into this jumped up tan screen.  Also, the sound is TOTALLY broken and sounds like little bits and pieces of static.

Since the game is about viruses, I did look it up just to make sure the 'glitch' wasn't a part of the story line.  But after watching a video of game play, it's -definitely- our version that's buggy.

EDIT:  There are also errors with Fred's Back

Pokémon Stadium 1 for the Nintendo 64, has sound issues and  slight graphics issues. Sorry if you already know this...

Here is the link for Yar's Revenge:

https://www.vizzed.com/play/yars-revenge-a2600-online-atari-2600-63656-game

It shows the normal glitched VCS screen, which is now used as turning on the TV in cartoons or video games.

I got problem,first two days was ok but now when i click "play game",i get new window that says:"Primary game ROMdownload status: 0%",and it won't move!!! What do i do?Thanx

Pocket Professor has a BIOS error.  I'm not sure if there are different kinds, so this one says: Unsupported BIOS function 1a called from 0800a5a6.  A BIOS file is needed in order to correct the behavior.

I'm not sure if it just me but whenever I try to play a Sega genesis game the screen remains black even when the game has loaded. I'm not sure if having vista may be causing the problem but I'm not sure what is.

Currently, this version of the Mario brothers games does not work:
https://www.vizzed.com/play/classic-nes-series-super-mario-bros-gba-online-game-boy-advance-9645-game

It does not load, just stays on a black screen.

EDIT:

Super Mario World Winter (https://www.vizzed.com/play/super-mario-world-winter-%5Bhack%5D-snes-online-super-nintendo-11519-game) plays fine but when you take screenshots (using RGR plug-in) it says the upload is completed but I am unable to find the screenshots I took when I click "Click Here to Retrieve, Add or Update your Screenshots." I believe it is uploading to a wrong game or somewhere else.

Famicom Mini - Super mario Bros (https://www.vizzed.com/play/famicom-mini-01-super-mario-bros-gba-online-game-boy-advance-9868-game) fails to load at all.

Well ive been trying to playing shining force cd on here for the past 2 weeks n it say =s that they will b ready by the 8th but ive been waiting n its the 9th n the game still hasn't been released to everyone I was just wondering wats going on with that

earthwarrior : If you could look over this thread:
https://www.vizzed.com/boards/thread.php?id=33941 and see if there isn't already this problem posted. I plan to look over that soon and post a list for each game and see if they can be fixed.

Singelli : Noted. It's difficult to find a replacement rom for Commodore 64 that will work, but I'll look into it.

darthyoda : Same as I replied to earthwarrior.

RetroGameNinja : That just means the Java emulator won't load the game, the Plugin works fine though. I've removed the java link from that page.

draskoni : When you installed it did you make sure to restart the web browser? Is the problem still there if you uninstall then re-install the Plugin? Failing that, does it work with a different web browser?

Singelli : That's normal since the external emulator the Plugin is built upon will give the same error to skip the BIOS. The game is playable though after clicking OK on the message, and then click back on the game.

earthblade : The fix is simple, it happens normally with the emulator the Plugin is using, but a prior update to the RGR Plugin was meant to fix problems a lot of users were having. Check this thread for how to fix it:
https://www.vizzed.com/boards/thread.php?id=47212

ruesen : I know how to fix those games, but I'm not able to. I'll have to ask David to change the ini file which the Plugin loads.

LegendKiller09 : There were issues in the coding which are being resolved and it will be available shortly.

Well I'm glad I came to u so I know wat is goin on I would really love to b apart of Ur game testing team cuz I can tell wats wrong with games and everything I know I'm just a newbie but I do have experience with games and know how they r played so I hope sometime I can b part of the testing team
