Nibbler-take 2...

LN2 · Post by **LN2** » Thu Nov 07, 2002 1:51 pm

I did some investigating after trying to play Nibbler at a difficulty setting of "hard" to match the TG settings for this game and to start trying to beat the 100 million score posted here at MARP for nibbler. It's the same score submitted to TG.

[rest deleted cuz it's moot now]

Issue with Nibbler in mame.

I have done more testing and have posted results at

http://www.permafrostsys.com/nibbler2.html

check that out. Any suggestions or discussion appreciated.
If someone else can test a PC version of mame and take that same screenshot for wave 25 at "easy" and "hard" it would be greatly appreciated.

When you start wave 25, just hold "up" and when you reach the top take your screenshot. Try it with dip switch setting at "easy" and "hard".

It's been explained to me that the dip switch settings are stored within the inp file....so even though I have the dip switch set to "hard", the inp was recorded at "easy" so the game plays at "easy".

I assumed the person played at TG settings which is "hard" given he had submitted this score to TG.

I found playing it at "hard" there are several waves that are impossible to complete on 1 man. There are enough of those that the length of game is limited where the high score could only be around 1 million at the most if a player didn't lose any men on any other waves except those that are impossible to clear on 1 man.

Oddly that is the first inp I have come across to override whatever dip switch setting I had. For many others I have had to alter my dip switch settings for the inp to playback correctly so it must only be for some games.

INPs are just logs of a game's input ports, of which the DIP switches are a part. MAME will always show whatever your settings are in the DIP switches menu, not what they are in the INP during playback, the simplest reason being, that they can change at any time, although most games only check DIP switches upon startup. So the DIP switches for any game will be stored in the INP. Of course, not all games have DIP switches either.

I wonder how he is able to get 25 million per hour on average.

even Tim McVeigh's 1 billion game took something like 50-52 hours.

so he was averaging about 20 million an hour. with scoring in mind that is about what I score also when in top shape...cuz then you build up men but then can sacrifice some leaving 1 gem to eat quickly with next man to finish the wave and get big bonus vs finishing it with little bonus. this manages extra men so you don't go over to reset back to zero, and results in faster scoring rate.

didn't time it...just about an hour I guess or a bit beyond it...It is only 20 million score...which isn't bad for the first hour cuz you don't score squat the first 15 minutes...but I wasn't building up men at all...too many stupid deaths.

more like my brain just doesn't want to do a certain move sometimes...

think with a bit more play I will be there...

playing the nibblero again now...had a 600k game before work today....won't submit again on that one until I top that 2 million score...whether it gets zeroed or not. I noticed that upload didn't include the wlf file....but recorded speed seems ok and the play seems fine so personally the missing wlf doesn't bother me.

I like the nibblero set better...more challenging...half the #men...not likely to marathon...

my findings report
.
rick carters' recording
.inp file size : 51,056kb
most snakes in reserve : 9
in emulation frames processed : 420,000
.
nibbler 69's recording
.inp file size : 36,074kb
most snakes in reserve : 21
in emulation frames processed : 297,000
.
my observation
i paid attention in nibbler 69's game
as to number of waves at 3,000,000 score,
99 waves.
multiply that by 10
and you guys did 'bout 1,000 boards each.

tar, interestingly I did something similar before seeing your posts.... hehe

his play on waves like # 80 are impressive...he gets through those much faster. he is faster on type "19" as well...but I am still improving there.

oddly though...would need someone to compare the dip settings in our inps...his snake seems to not get as long as mine.

his play seems legit...but cheats are enabled on his submissions. Please advise him to have cheats off.

Here are the stats I gathered...after finish of wave 99 before it goes back to wave 80:

Code: Select all

                  nibbler_69           ln2
#frames      83,463             107,676
#men            7                       5
score         5,302,580          4,708,800

I was only on wave 77 when I hit the 83,463 frame mark.

nibbler_69 has cleared 22 more waves than I have at that point of the game.

more interesting though...is that is about a 23% difference...same for # frames after wave 99...

yet the score difference is only about 12-13%. odd ehh? 200k of that can simplbe in a few waves where nibbler_69 dies with 1 gem left and quickly gets that for a near 100k bonus while I am only getting a 10k bonus on a couple waves....so the scoring difference might be a matter of timely deaths....instead of stupid deaths which I was still having. hehe

I remember when I was in shape(look at my 200 million one or 100 mil for the secnd set) that I was at 5-5.2 million after 99.

I always remember using 5 million as a mark to reach after 99...so I am definitely short of that.

this is mostly from 2 wave types that I mostly survive on but get very little bonus points on than once I get them down a bit more.

hmm, that would be a very interesting track!!!
score after wave 99!!

maybe we should use this for 1 of the 3 rom sets that are basically the same game.

nibblero is different and more challenging already.

perhaps nibblerb would be good for that wave 99 thing.

removes marathoning...and focuses on strategy as well as skill to max score after wave 99.

If he use cheats for record then when you playback game you must enable the same cheats for watch 'cheat game'. If you don't have enabled the same cheats as he -> game will not playback properly.

I just confirmed the score i didn't check for blatant cheating... I would welcome a non marothoning option if there isn't a clone that already exhibits this behavior.
