ROMs problems

Hi guys
I load to my GBZ some ROMs and I stayed very upset. I have not found even one a game that would not go without problems. The games either do not start or is graphically "broken".
Can you help me in what could be the problem? Something has to be set up?
All games I tried the Raspberry Pi 2 and go without problems.
For demo I recorded this video:

I also have problems uploading ROMs via wifi. WiFi running, but I regularly happens that during the transfer roms throws error and have to restart the entire GBZ to restore the connection. I was wondering if it can not be mistakes in this, that it was wrong for the transmission of copies.
Thanks for any advice, because my GBZ I had already pieced together, but without games...

it's normal to see some games not working . but not like this ..
It looks like Bios problem or you changed the emulator settings ?
did you install gba Bios ?
when the game boot up
It shows you a gray box

Sorry I'm out, otherwise I will give you my GBZ settings
The folks here will help you.
And for transferring roms i prefer to use USB
it's better and faster then wifi

Thanks ABH.
I installed gba_bios.bin and gbc_bios.bin and not help. GBA ROMs is already loaded, but have the same problem as everyone else. So either show only the white / black screen or is broken graphics in the game
Any other idea to solve the problem?

I've found that some ROMs (especially GBA ROMs) have issues with the default emulators in RetroPie. For those ROMs I usually test some of the other emulators (a lot of 'consoles' in RetroPie have multiple emulators preloaded in to the OS) to see which works best and set that as the default for those specific ROMs.
With regards to the GBC ROMs try renaming one to a standard GB extension and placing it in the standard GB folder in RetroPie this fixed an issue for a couple of mine, sometimes you also have to do this if the Scrapers don't pick up the GBC info.

I've just double checked my RetroPie Tablet and can see that I changed most of my GBA ROMs to the 'lr-mgba' Emulator if you want to maybe try that?

Thank you for your advice. In this I am but an amateur and do not know how I get there "LR-mgba" emulator.
When starting the game and subsequently entering the setup menu I have to choose just one emulator for all ROMs lr-gambatte (GB and GBC), lr-gpsp (GBA).
You're doing all right without any problems after installation? On Raspberry Pi2 I did not have to set anything and almost all ROMs triggered me. Here, on the contrary, almost all of me does not start or starts with errors

When you select a ROM a grey box appears on the screen similar to this one, press any button.
Another box will then appear similar to this one.
You can either select to change the default emulator for that 'console' or the default emulator for that ROM. For GBA you will be given the options of;
lr-gpsp
lr-vba-next
lr-mgba
gpsp
You can then either exit this menu or launch the ROM from this menu.

If you have any trouble doing this I'll try arrange some time to record a video showing you this.
