I recently acquired a lot of Atari 2600 games. One of them in the lot was Great Escape. I know that the NTSC version is quite rare, but no one really helped indicated how to tell the copy is an NTSC version. I looked all over. Anytime something does show it, its the boxart only not the cart itself. I tested the game on an Atari 2600 using RF and an Atari 7800 using composite. I used two different TVs. On both of them, the picture didn't roll and the colors looked pretty faithful to those of the screenshots online. This game comes in a special Bomb cartridge in which Bomb is inprinted on the backside and both sides have ridges. On the back of the cart, it says Hong Kong in tiny letter near the top. I heard games made by Bomb were made using Eproms. The cart is still working so nothing has deteriorated yet.
Here are the details of my copy that's different from the PAL copy that usually comes up
- There is a black sticker on the back which states Q.C. PASSED N not Q.C. PASSED P
- Underneath "Copyright by Onbase CO. LTD" it doesn't say "Printed in Hong Kong CA282"
- The label looks a bit glossy and saturated.
I attached some pictures.
