What does it mean when it says Region free for a PS2 mod chip?

Question

I was looking to modify my PS2 and it said "DVD region Free with RCE support:
Watch all region DVD movies on your PS2." Does that mean it'll play imported games or it will just play imported DVDs?

The mod chip i was looking at buying was the DMS4 E.Z.I. S.E. Lite

Answer 1

DVD and PS1/2 games (as well as VHS, TVs, etc.) have different regions. Most common: PAL/SECAM, NTSC. For Playstation systems there are three regions:
1). PAL - Europe, India, Australia, etc.
2). NTSC U/C - America, Canada, etc.
3). NTSC J - Japan. etc.
(For movies it's a bit different)
That modchip will allow you to play movies from all regions and zones.
Games from all three zones will work too.
