On a personal note, I want to thank Carlos for the time and effort he volunteered on this. I have gotten to know Carlos over the last month and a half or so by virtue of living in the same area, and it's amazing how a friendship can be stemmed through unique circumstances. And here it is.............



"By the time I saw the dispute, it was over 150 pages long, jam filled with information and allegations, beginning from what I read with the swipe vs. pop graphic, which was caused by the shutter effect.



Next was the converter and it’s operation. The converter produced a duplicate or lagged image was the claim. I demonstrated that it’s not so on a CRT, where the spare screen was ahead of the actual Arcade screen.



Next we had that the converter would not have been used because it doesn’t record color. This issue was cracked using a specific brand of VCR that was around before the creation of the tape.



Next we moved to the issue where the dispute claimed that after a lot of testing, Mame’s Version 0.116 through 0.121 mimic the stage transitions on Billy’s Tapes & previous versions didn’t. What I found was based from Mame development that those versions came out about 2 years after the creation of the 1.047 Billy Tape.



Next came that previous mame versions with modifications and tweaking on the settings, plus refresh rate modification, would mean that you can produce an image which looks close to the stage transitions.



With so many changes and modifications, plus page after page of suggestions, I turned my focus on testing the broad functions of the Genuine Nintendo DK Arcade PCB. This includes the way it was recorded using the devices in hand and what was available at the time of the creation of the tapes.

2 Genuine DK boards were used for testing, and 1 DK Double modified board, a 60 in 1 board, 16 in 1 board and 2 versions of Mame on a home PC Laptop. Most of these tests when performed were recorded and captured to share among the others which were also running tests. Most of these tests were not released publicly but are stored. Recording Mame from a computer, moving to a DVD, playing to a VCR recording, and recording from a capture was done to find differences and similarities.



Though the famous finger(Tail some call it) on the girder was a long focus in the research, after so many boards and finding many video plays from other DK players on YouTube... The patterns began to become much more clear. Similarities that could be seen on one type of DK vs a DK played on an alternative board.

After MANY hours and looking at frame by frame of the test recordings, others play and the recordings I produced in my personal testings for evaluations were taken into account.....



My Conclusion on the 1.047 & 1.050 game tapes is that they were NOT generated from a Genuine Nintendo Donkey Kong PCB. The signatures which are normally produced by those PCB's are NOT on the recordings.



Repeated testing and viewing of the game on those tapes do not demonstrate the signatures found on recordings coming out of Genuine Nintendo Donkey Kong Arcade boards." End Quote.



Again in closing I applaud Carlos for his unbiased and independent research, study and testing on this matter, and I hope regardless of which side of the dispute you are on, that from a technical standpoint, you can respect and appreciate the work put in just like both of us do for Jace and the TG Staff. Cheers
