What was that home system you could plug old arcade boards into?
Was it the Neo Geo?
I seem to remember that it was like a home console,but instead of buying cartridges,or CDs,you bought the arcade board (like what was mentioned above) & plugged it in,just like an arcade machine!
There was even a company produced a games station that looked like an arcade machine,and you could put a tv & console in it,for a more authentic experience!
