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 ROMs is a
corrupted upload to a release.
[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!
