One thing I just noticed with me test setups - MAME .122 is set to not rotate, but appears to be rotated 180 degrees.  If you look at my arcade captures, the high score is on the right of the screen.  This is also true for the videos we see of the rotated tv's that are used to display the playback.  However, MAME .122 produces gameplay with the high score on the left of the screen.  This is true whether it's the arcade CRT (VGA out from an ArcadeVGA card) or on my LED, VCR etc (composite out from ArcadeVGA).  It's unlikely the AVGA card is doing something with the signal, because the windows desktop and everything else displays properly oriented.  Just something I noted, not sure what bearing it has.  At a minimum, possibly something that needs to be considered when comparing all of my MAME video to the Billy videos.

At any rate, here are pics of the CV-04.  I think that gets a clear picture of all the chips on the board.

thanks for the closeups, sadly i cant see the markings on the chip. Is there anything written on it?
tbh though looking at it, it seems very very similar to how the twobits is designed, and wouldnt suprise me if one was made off the back of the other, either that or its just a standard technique.

apologies, id only clicked the first one and saw the flash had erased the number.
heres the link to the chip http://datasheetz.com/data/Integrated%20Circuits%20(ICs)/Video%20Processing/BH7236AF-E2-datasheetz.html
It seems it has a built in delay that i cannot find any info on, but tbh id expect it to be no greater than 20us (0.2ms).
im pretty sure this is the one the jrok uses https://console5.com/techwiki/images/f/fb/CXA1145PM.pdf which is very similar and possibly an alternative chip to the BH7236. It operates with a 10us delay (0.1ms).

interesting enough theres a diagram here on howto connect the two bits device to a cga monitor.
https://web.archive.org/web/20170618044418/http://www.twobits.com/RGB/cga.gif

and here explains howto invert the positive signalof your board to a negative one
https://web.archive.org/web/20160422221734/http://www.twobits.com/RGB/sync.html
You may notice this conflicts with what mr childs says in his long post! He states the signal needed to be converted to positive instead of feeding from the boards negative signal. However the converter wants a negative signal,and even if it did need positive then this could of been taken directly from the nintendo on board inverter. There would of been no need to build a seperate adaptor, and even if they did it wouldnt of worked anyway as theyd of been feeding it positive where it wants negative.

after watching the 1.06dk video for the 7 millionth time it finally dawned on me that its been recorded to vhs sideways. You can tell because the static lines are vertical and not horizontal. The two bits device outputs to a standard size screen and will fill the screen the best it can. There would be no reason why it would record sideways.

If i may add my own personal opinion, then at this time, it seems its possible that the game footage was recorded via pc, the screen was flipped, and then transferred to vhs. Maybe at the time TG wouldnt accept a digital recording? so this passed off as a direct feed to vhs.

Theres a few other things ive spotted with the 1.062 recording but its just speculation as of yet so i will do more research and report back if im confident its not just a conspiracy to add to the pile!

apologies if this is superfluous/has already been done, but i've compiled animated gifs from the recently-uploaded "Big Bang 2010 - Billy Mitchell DK & DK Jr Record Announcement" clip published by GDLarcade which provides footage from a different camera. the clip's video is inferior to xelnia's upload of the same scene, but it shows the transition screens. exposure/shadow (?) issues occasionally obscure parts of the GDLarcade footage, making it difficult to discern, but maybe it can still be used to refine conclusions. xelnia's is cropped but much easier to analyse.

the structure of the gifs is as follows, Frame #:
  • second-last frame of screen wipe
  • last frame of screen wipe
  • first frame donkey kong stack
  • second frame of donkey kong stack (followed by several excised frames of the donkey kong stack)
  • second-last frame of donkey kong stack
  • last frame of donkey kong stack
  • fourth-last frame of screen build
  • third-last frame of screen build
  • second-last frame of screen build
  • final frame of screen build

i've included the frame number in all gifs at the top-left, except for xelnia's which is at the bottom-left. all frames are one second long except the last (#10), which is three seconds long. the bottom-right gif is cropped from xelnia's upload.

As dk is a vertical game, yes it will appear to be on its side if displayed on a monitor that is horizontally oriented.

thanks for confirming, that was the last post before bedtime so hadnt looked it up!

another thing to note that would goin billys defence is that the jrok board apparently is known for pushing the displayed image slightly to the right. I cant find where i saw the post but here or tg someone mentioned the vhs recodings are off centre to the screen. This issue could also be present with the twobits device?

^That would just mean that whatever was coming out of the cabinet was going through the two bits device, or something causing an offset, but not evidence of whether the signal was MAME, VCR, arcade or anything else.

SHLONKY, it would be best not to make speculations or guesses.  This is what the Billy team is doing and that's why their statements can be torn apart so readily.

Yes DK's video is sideways.  MAME can also output the video sideways with the -norotate option.   The first two Billy tapes are sideways but in the opposite orientation of actual DK video because MAME's -norotate option rotates the video the wrong way.  By Billy's third videotape the game is rotated the correct orientation because they probably realized they screwed up the first two times, but the dimensions of the playfield and the size of the borders are completely incorrect for DK PCB video.

The Two Bit device could not do any such thing as "fill the screen the best it can".  It does not modify, recompose, resize or rotate the video.  It simply combines the R,G,B and SYNC signals and multiplexes them into an NTSC composite signal.  No brains, no framebuffer, no processing in the device whatsoever.  It's a 2$ chip on there, it can't perform all these things people are attributing to it.

hi, i put my personal opinion aside from my findings, please dont think i combine the both together! I understand you can rotate the screen in mame, but my point here on dkf is to just put forward my findings that the DK footage was NOT originally recorded on VHS. If anything this goes towards the mame theory, but because i do not know exactly how mame draws to a screen then i wont pretend to be able to help in that area. But where i can help...i will!

when i said "fill the screen" i didnt mean it was altering the image size, i just meant it will not window the output as seen in the dk 1.062 video. If you read my original post on page 9 youl understand what i mean. The vhs viewable area is way different to the original recorded area.

thanks :)

Ah.  My guess (and just a guess so I never brought it up before) is that maybe for the 1.062 recording MAME was simply set to higher resolution screen mode and scaling turned off, making the gameplay slightly smaller relative to the screen area.    Someone could probably do some math to figure out what resolution it might be.   DK is 256X224.  If the PC was set to 320X240, lets say, there'd be a black border all around.

 Joel asked me to post this regarding the situation. While I personally do not agree or in concert with Joel on many matters that have nothing to do with this dispute, I feel there are some points addressed in this message and questions that have yet to be answered that everyone should take a look at.... Thank you...

It is important to look at two areas of salient points from Robert Childs’ Video Analysis:

Relating to using a RGB to NTSC Converter to a camera:
1. The visual Billy saw on his monitor was the same as Steve Wiebe saw on his monitor.
2. Billy could not see the feed going to the saved tape while playing.
3. Billy had no advantage by using a video converter.
4. The only advantage to using a video converter was to the camera owner. A camera could not be knocked over standing on a tripod behind the player.

Relating to the legal and common-sense aspects:
1. Looking like MAME is not MAME, nor a violation that even approaches “cheating”.
2. The accusation of using MAME doesn’t make sense. It would be too much work.
* The risk would not present enough gain over the possibility of being discovered.
* Any player who could get 1 Million nearly 8 years ago on MAME would be able to probably get more on arcade than a mere 1,062,800 points. This is speculative but a highly possible speculation.
* If Billy was so well versed on MAME, when arcade scores became beyond his current reach, why did he not “retire from arcades” and go onto mastering “another platform”? Cheaters love attention … that is WHY they cheat. No one was close to 1M in MAME at that time. Why did he not do this? Fear of discovery? No. If he had put a computer inside an arcade cabinet, he would be brazen enough to switch platforms … because he craved the attention. Cheating is like an addiction … once you “get away with it’ the next time is easy, and oft times bigger. Billy has submitted nothing since 2010.
* If I remember correctly, MAME had a certain amount of lag on some games at that time. That would have been a negative for using MAME if it applied to DK.
3. Even IF …
* the prescribed method of verification at that time was put aside (which would be “changing the rules after the acceptance of proof”), changing the standard of proof after acceptance is an unfair standard.
Even IF …
* multiple eyewitness testimony is discounted (which it should not be) … when a dispute is involved and the tape is missing from TG “archives”, as it is in this case, when representatives present of TG at that time are not consulted or even “trusted” to comment their remembrance … then other standards that HAVE been used in the past (eye witness testimony, etc.) MUST be used.
This situation is NOT to certify a NEW record/score, but to confirm an OLD, ALREADY EXISTING score. Therefore, TG would NOT be violating their current standard of accepting video only to verify a record because this is NOT a new record.
The goal is to establish the validity of THIS record/score, already once certified by older standards.
Using the standards of the past when current standards cannot be met, mainly because TG cannot find the tape in their “archives”, that is NOT the fault of the player.
4. Even If ...
TG would dismiss the effort to find the video footage that was in their possession WHICH IS TG’s RESPONSIBILITY to produce since they initially certified the record … if they dismiss THIS record because they can’t “find the tape” then how many THOUSANDS of OTHER records/scores MUST they AUTOMATICALLY dismiss upon any challenge?. That act alone could start an avalanche of revenge seekers seeking to remove whatever they can because the rules “allow it”.
HIRE MORE STAFF, cut into the profits, the floodgates are about to open!
* TG has a responsibility to honor tapes that were once in their custody, regardless of ownership changes, especially if they cannot “find” a tape that was in their charge to protect. Once in their “archives”, whether they deny this duty, real or implied, it is their legal fiduciary duty.

SIMPLY PUT: NO SCORES involving once submitted tapes should ever be removed should TG not be able to put their hands on the tape they once certified as a legitimate score. Once they have it, it’s their responsibility. NO EXCEPTIONS. This is an ALL or NONE precedent.

If TG allows “challenges” without reasonable proof, they essentially are allowing accusations of innuendo and/or suspicion. That is NOT what the Dispute System should become … a grudge system to punish those whom one is jealous of and does not like.

I propose discussions to change this system. While one may agree or disagree with the Todd Rogers decision, the challenge issued to his situation involved a standing world record. Billy Mitchell’s score was no longer even in the Top 10. This leads to strong belief that this served no purpose other than to harm Billy and TG allowed it.
I propose that TG ONLY allows challenges:
1. On standing World Records
2. Require reasonable proof, not speculation, suspicion, or innuendo.
3. Examine the motives of the one submitting the challenge … search social media for harassment, threats, or promises of “getting even”. This is preliminary work that TG should do to prevent the misuse of the Dispute System, a “due diligence” to prevent “frivolous” challenges and to PROTECT ITS MEMBERS.

Example: one World Record that was thought “a fake” was the former (now #2) world record on Q-Bert. George Leutz struggled mightily but overcame that score after 84 hours and 48 of play. Even tho EVERYONE thought the previous record was fake.

Billy found out about this challenge as when most people did who do not frequent the forums by a TG Facebook post on Friday, February 2, 2018. Billy isn’t on Facebook, so someone had to alert him about it via email.

As it stands now TG does not notify the owner of the disputed record. It is up to the challenger to “prove his case”, and then the record is removed. It would seem that TG should have the interest of both the challenger and the challenged member at heart. Now, if a member is not on the TG forums and/or Facebook … they essentially could have their record removed without knowing about the challenge or having a chance to defend themselves before removal.
How FAIR is that?

The challenge of Billy Mitchell’s old DK world record, not currently even in the Top 10 is a prime candidate of jealousy and vindictiveness. Oh, Billy DID THE SCORE, but there is wide-spread jealousy because of the movies, personal appearances, the persona, fame and attention. Current Top DK scorers will NEVER achieve the fame the Pioneer did, no matter how high they score. TG should take challenge disputes rooted in emotion and personal attack into account and not allow them.

I propose these ideas as the basis for an improvement in the Dispute System. We all know how things will work out if Billy is proven guilty. How will Billy recover from the personal attacks, the embarrassment, the loss of respect, the loss of business and the toll on him and his family when he is proven innocent? Will TG or the froth-filled forum members even apologize? If they did, what would it be worth? Remember, video games are supposed to be fun, not blood sport that harms your personal life..

Legal aspects?


Legal in what sense? This isn't a law court.


This is bluster from the off, trying to appeal that this could be a quasi-legal case when it is not. In the US you can be sued for anything instantly.


Looking like MAME isn't MAME?


So, looking like Arcade isn't Arcade if you use the same thought process


It would be too much work?


What does that mean? Define too much. An afternoon, a day, a week, months?


The risk would not present enough gain over the possibility of being discovered.

Only if you thought you might get caught

MAME had a certain amount of lag on some games at that time. That would have been a negative for using MAME if it applied to DK.

Not a problem if you save state. If you encounter lag, just retry. This could have been done over and over.

I thought dwayne did the score? It's hard to keep up with the nut-swingers.

Jealous of Billy's persona?

Jees-oh.
