Liking the looks of Last Strike there.
Never owned a Jaguar but I've always thought it would be something I'd pick up eventually. Are Jaguars region locked?
There is no region locking and I'm only aware of one title (Jag CD/Space Ace) that does not work in PAL. Some games are "PAL Enhanced" (they fill the screen, eg Raiden), these are denoted with a "P" code on the cart serial.
However, they are trivial to mod for 50/60Hz with a toggle switch. All mine have that done to them
