1 is Kangaroo, 2 Arkanoid
If you want to make identifying simple, buy a cheap eprom reader and use Romident.

compare with images on google, yes it is very similar...

Is there a method to connect a pcb when you don't know the model?

You'll have to start to ID The +5V and ground connections. Sometimes you can visiually see which track runs to a test point labelde GND or +5V. The GND and +5v are usually thick tracks near the edge connector and run across the board. Usually they are on the far edged of the connector.

If not, find a chip which you know the pin out off for the +5V and GND and use a multimeter to see to which pins on the enge connector they are connected.

Next power up board and probe all the other pins with a scope to ID the audio and video signals. Needs some experience to know what they look like.

If you found out the video signals hook it up to a monitor so you can see if it is OK.

The rest are usually inputs so you should USUALLY short them to ground one by one with a piece of wire to see the responses on the game. Some rare boards inputs are switched to +5V  though like Asterock so be very caredful with this....but these are really exceptions.

Béla's suggestion to ID the board is much easier and safer though. With the info you find you usually can find PIN outs on the net.

Hi, number 5 is for sure a Hammering Harry bootleg pcb.
