N64 markup legend - [!] [b1] (M4) [h1]?

Question

After downloading a ZIP archive of a Nintendo 64 game (ROM), I noticed that it contained every version of the game. I would only like to keep the version of the game that is the best and delete the others to save disk space. Each ROM has a different markup or tagging system. Could someone please tell me how to understand these tags so that I know which ROM is the final and best version?

Example:
Army Men - Sarge's Heroes (E) (M3) [!].z64
Army Men - Sarge's Heroes (U) [!].z64
Army Men - Sarge's Heroes (U) [b1].z64
Army Men - Sarge's Heroes (U) [f1] (PAL).z64
Army Men - Sarge's Heroes (U) [t1].z64
Army Men - Sarge's Heroes (U) [t2].z64
Army Men - Sarge's Heroes (U) [t3].z64

So basically, I would like to keep only ONE.

Thanks!

Answer 1

[!] means verified good dump - someone played it all the way through and found no glitches.
[bx] means it is a bad dump. Toss it.
[hx] means it is a hacked version. Someone bastardized the game by changing something in it. Toss it, unless it is interesting.
[tx] means it is a trainer. It has been hacked to make it easier to play.

The Letters in parenthesis indicate the language or region the ROM is from. choose (U) if you want USA. (E) is europe (J) is japan, etc.

The (M3) Means it has 3 different languages on it.

From your list I would keep the second one.

BTW - each file works independantly and you do NOT need to keep them all.

STANDARD CODE NOTES
[a] This is simply an alternate version of a
ROM. Many games have been re-released to
fix bugs or even to eliminate Game Genie
codes (Yes, Nintendo hates that device).

[b] A bad dump often occurs with an older
game or a faulty dumper (bad connection).
Another common source of [b] ROMs is a
corrupted upload to a release FTP.

[f] A fixed game has been altered in some way
so that it will run better on a copier
or emulator.

[h] Something in this ROM is not quite as it
should be. Often a hacked ROM simply has
a changed header or has been enabled to
run in different regions. Other times it
could be a release group intro, or just
some kind of cheating or funny hack.

[o] An overdumped ROM image has more data
than is actually in the cart. The extra
information means nothing and is removed
from the true image.

[t] A trainer is special code which executes
before the game is begun. It allows you
to access cheats from a menu.

[!] Verified good dump. Thank God for these!

Answer 2

Umm... You might be more proficient than me in this field, but I wouldn't mess with that stuff.

When an emulator plays a ROM, it uses the entire .zip file, not individual parts of it. Deleting some of them might make it not work correctly. Besides, .zip files don't take up much HD space (in fact, they're specifically designed to take up as little space as possible.)

But hey, if it's that important to you then go for it. If you screw something up, you can always just download it again.

it is what we call actual sportsman spirit and actual gents. they have great mutual appreciate for the different and we would desire to be proud to have them in cricket. yet i comprehend somebody will come right here and submit a commentary which may be anti Indian or anti paki or anti lankan pretending to be the only from those international locations and the section would be crammed with hatred back. and that i admit that i'll be the 1st one to abuse if there is any undesirable mouthing approximately indians. while our gamers play with great appreciate with one yet another and have no longer something against one yet another then why the hell are we struggling with right here? can no longer we make this section a organic expertise sharing one without racial abuse and hatred? in any case, hats off to u that u have been attempting to ask honest questions and attempting to do away with hatred. a minimum of somebody cares.
