Opinions Follow, Tread Lightly:
Relevance is key with a scoreboard; I personally would prefer a shorter list of Verified "cheat proof" scores over a longer list of potentially "in-comparable" scores. The fact that this list isn't the TG list doesn't imply that our level of scrutiny be any lower. I see the valid issues with modern versions of mame or other Xin1 emulators; The potential to cheat with modern mame versions and the gameplay differences of various emulators has been discussed thoroughly, both Dean and Hank have given their opinions on the matter.
We must realize that scores such as Svavars' and Robbies' were "grandfathered" into the list due to general community acceptance, previous proven performance (in accepted venues WCR2), and during the developmental phase of the rules that govern this scoreboard. The acceptance of these scores are not a precedence for further "bending of the rules" they were exceptions, and should only be viewed as such. Both Robbie and Svavar understand the rules that govern the HSL of DKF and neither had issues with the potential DQ of their scores from the list; Svavar even went so far as tho ask that it be removed, to prevent controversy.
My opinions would vary if access to the REQUIRED version of wolfmame cost money, but anyone with a computer can get the right version of wolf and the correct us set 1 roms; NO ONE is IN ANY WAY prevented or limited in their access to a potentially valid score.
That last sentence sums everything up; We have agreed upon a "cheat proof" version of mame, that is READILY available for anyone to download, FOR FREE. If you feel the need to go above and beyond and buy a cab for your personal arcade, then by all means do so, Just know that you need a TKG4 boardset for your submissions to be valid. I totally understand the appeal of Xin1 emulators for space, price, etc.
Bottom Line: If you want to play on an Xin1 or have reasons to play DK on other versions of mame, by all means go ahead and do it, just know those scores aren't not valid on the DKF HSL, for reasons that have been beaten to death by the TOP players in this game. If you want a score on the scoreboard, then either download wolfmame FOR FREE, or buy a TKG4 boardset.
If you can afford a cab, then that is a personal luxury that you choose to acquire; simply spending X-hundred dollars on a cab doesn't mean its' scores should be valid. That is like giving special privilege to those who can afford any type of MAME or Multi Cab and that's bat shit crazy.
The required versions of mame are free, allowing any input type you want, on any screen you want, how much more flexibility do we need? Just download it and put up a score or play on a TKG4 boardset, and forget about the grandfathered scores, they have no relevance for future submissions.
