Rom types

[sajr89]

I have found different that there are multiple ROMs for certain games. Like, let's say for instance, Army Man - Sarges Heroes:

There are -
Army Men - Sarge's Heroes (E) (M3)
Army Men - Sarge's Heroes (U)
Army Men - Sarge's Heroes (U) [b1]
Army Men - Sarge's Heroes (U) [f1]
Army Men - Sarge's Heroes (U) [t1]

Sometimes I find something like - Army Men - Sarge's Heroes (J).

What do the E, U and J mean? And also the M3, b1, f1, t1?

Does it matter? If there's any experts at this, then please answer me. I usually try to use the one that says U (I think that stands for US, J stands for Japan, and E stands for Europe - that's my guess).

Thanks in advance
