Yes, more info on AK LE would be great. I do not know what sort of serial number system was used on those. It is possible they started at -00300 or -00301 and went up from there, since regular AK serials only go up to -90209 or -00300. So -30308 would indicate PCB number 38.

BTW, on a somewhat related note I have seen Mushi Matsuri 1.5 serial MHN-20005, so we know at least 25 were made.

There's also this: http://collectedit.com/collectors/shou-time-213/arcade-pcbs-281/mushihime-sama-cave-festival-ver-1-5-japan-by-cave-31982

It appears to be a Mushi Matsuri V1.5 with serial 3970 (or 3920, hard to tell), indicating a Matsuri version converted from a regular Mushi.  So apparently there are more than just the MHN- serial numbered boards.

I've noticed something interesting about Akai Katana PCBs. The first 100 or so appear to be freshly made PCBs. See, for example, this PCB from tops (serial AK-20002, which means it was the 22nd one made):

https://www.tops-game.jp/products/detail.php?product_id=5499

Only one date stamp on the back, and the date stamp is from August 2010.

However, mine and two others I've seen with the RUN number 2 (e.g. AK-XX2XX), including this one currently on YAJ, are clearly reprogrammed DDP DFK PCBs, because there is a date stamp from May 2008 and another from August 2010. Anyone have one with a RUN number of 1? Basically, I wonder when they started reprogramming older PCBs to fill in the AK production.

EDIT: I see forum member Monouchi's PCB has a RUN number of 1! Hopefully he will let us know how many date stamps are on his PCB.

I hadnt notice. Yeah my pcb is AK-70105.
I will check for stamps tonight and grab some pics.  :)

My Akai pcb has two stamps on the same white sticker:
08.5.09 and 10/08/09

Thanks for checking! So, it is just like mine. And now we know they started reprogramming DFK PCBs beginning at least at the 175th Akai Katana PCB.

Mine is AKU-20303

Thanks for the info! Looks like you have PCB #23, and they made at least 38. My current hypothesis based on these data is they actually made 350 Akai Katana PCBs (same as SDOJ!), but didn't sell the last 50, so converted them into AK LE (and added new serial code stickers, but interestingly retained the AK serial code numbering system). This would mean there are no more than 50 AK LEs out there.

What kind of date stamps are on the bottom of an AK LE PCB?

I think you are right about that, although it is kind of weird they would print new serial stickers and start at 300 instead of 1.  Is it possible that they weren't converted and always intended to be sold as limited versions, any idea on the time-frame when the LV was released relative to the normal version?

August 2010 for Akai Katana
November 2010 for AK LV

Good idea that the serial number system for both games was planned from the start, and thus the last 50 were always planned to be AK LV.

The "U" in AKU probably stands for "User" (home user ver).

Tops added a DFK BL PCB to their stock today. It is serial number DDB-00200 = (200th PCB out of 200 made). This is significant, because I believe it is the first time we have found the 200th PCB from a postulated run of 200 PCBs. If we ever find a higher serial, however, we will have to adjust our estimate upward.

I just want to pipe in that I read that and thought it was really effing cool. I know that this whole thing is a niche within a niche within a niche... but as a numbers guy, it is deeply satisfying to see. It's like all of the data has accurately made its predictions, and that makes this PCB kind of special. It's probably the last DFKBL ever printed!

Yeah, I thought it was pretty cool too.  :righton: I had been wondering if they went up to -90109 for the Black Labels or if they rolled over to -00200. So this solves that mystery.

Update on the production estimates -- I moved DFK 1.5 from the "common" category to the "somewhat common" category and revised its extant production to 500 ~ 550, due to good evidence that 200 of the original production were reprogrammed to Akai Katana by CAVE.
