I don't know why this came to mind, but anyways, I was under the impression that this cart used a rather unique PCB, if this is so, how the hell have there been repro's made?

From the photo I saw of the original PCB (cant find it now) the mapper looked very simple. It was just a 74161 chip which means it could be standard a*rom, b*rom, cnrom, u*rom. I may be able to pick the exact one if I can find the picts again. If anyone has the rom they could also easily tell by just looking at the ines number.

Wow. Bunnboy finally made it over to the site. Glad to have you hear man, you should start posting more often and be friendly

afaik the Airball Rom's are not released and there are only like 3-4 known copies of it to exist in proto form. Then we have seen a handful of repros, 2-3 I think.

Ive been reading these forums for a while but apparently never registered... Havent been buying too much recently, mostly just looking for perfect black box games and gray nwc.

Was there a site with the Airball pcb picts? I just remember the board looked somewhat transparent. Only reference I have found to it being a complicated board is the nesworld interview ( http://www.nesworld.com/hindorff.htm ) It isnt really clear what part was custom, could have just meant it was a generic mapper but one Tengen hadn't used before. Or the protos do not use the final hardware and are just incomplete. Easy way would be to have one of the repro buyers open up the cart. I would bet inside it is just a plain Tengen or Nintendo production board with eproms wired up.

I have pics of the board somewhere. I actually had one of them for a few months selling it for one of the owners. They might be in the NA database, I haven't looked to be honest.

I know you haven't been buying much, cause I havent seen you outbid me in a while You were a buying machine there for a while.

BTW-- I bought one of your retroUSB ports and man that baby works great. Well worth the cash IMO. I use it everday to take screenshots for this site.

Duh, check the database! Yes there are two pcb pictures in there. It is clear the two mapper chips are a 74161 and a 7432 and it uses 8KB sram. Those chips are the same as the Nintendo UNROM, a very common mapper. The 27C010 eprom chip is also a common 128KB which is the max the UNROM board supports. Now someone just needs to make the rom publically available...

Interesting stuff That is a unique Tengen pcb, none of their other games use that one. It would be cool to know the PCB name, which should be on the back of it, most likely something like 8000xx

Looks like it would be possible to use an UNROM pcb as a base, might need some rewiring to the 161/32 unless Tengen used it exactly the same way.

Yes, where is that ROM dammit!

the board type is 800049 01 Rev A I scanned it all when I had it in my hands
