Miscellaneous: Sneak/Hide messages (timeline changes)

[Rygar]

I searched but didn't find anything on this.

Here is how I believe sneak messages should work on P99 (these are Rogue only obviously):
<[July 1999] no sneak messages exist
[July 1999] to [June 2001] sneak messages implemented as follows:
Sneak Success:

You are as quiet as a cat stalking its prey.

Sneak Failure (note the grammatical error... missing the " a "):

You are as quiet as herd of running elephants.

[July 2001]+ sneak failure message fixed:

You are as quiet as a herd of running elephants.

Here is how I believe Hide messages should work on P99 (I found source saying these are rogue only, not sure if implemented on P99 or not):
<[July 1999] no hide messages exist
[July 1999]+ hide messages implemented
Hide Success:

You have hidden yourself from view.

Hide Failure:

You failed to hide yourself.

This site mentions a July 27, 1999 patch implementing sneak/hide messages just for the rogue class:

In the update on the night of July 27, 1999 (Japan time), a message (success/failure) when running Sneak was added. It's a nice change to be able to see success or failure without actually walking. However, it seems that this message only appears for Rogues, not other classes.
　Message when the skill succeeds: ``You are as quiet as a cat stalking its prey.''
　Message when the skill fails: ``You are as quiet as herd of running elephants.''

Initially, Hide did not know whether the skill was successful or not, but with the update on July 27, 1999 (Japan time), a message was added when Hide was executed, making it possible to judge whether it was successful or not. . This is a very welcome change for Rogue. However, this message appears to only appear in Rogue.
　Message when the skill is successful: ``You have hidden yourself from view.''
　Message when the skill is failed: ``You failed to hide yourself.''

6/27/2001 patch mentions lots of spelling/grammatical fixes, where the rogue sneak failure message was updated

Pasketti parser V 0.8 was posted on 7/13/2001 where his change log mentions the updated sneak message

Understands new corrected sneak failure message.

Note he made a parser for the actual log, he sent me the code so very confident on the timeline verbiage change:

  {"You are as quiet as a cat stalking its prey.", TrackCounter, (long) &CurrRD.SneakSuccess, 0, 0, 0},
  {"You are as quiet as a herd of running elephants.", TrackCounter, (long) &CurrRD.SneakFailure, 0, 0, 0},
  {"You are as quiet as herd of running elephants.", TrackCounter, (long) &CurrRD.SneakFailure, 0, 0, 0},

Thanks for your time!
