Has anyone seen any of the following?
  • Namco(t) 106
  • Namco(t) 175 not as epoxy blob
  • Namco(t) 340 not as epoxy blob
If so, might you provide a picture? It's weird that the family seems to be named after a parent IC that I've found no direct evidence for.

I did find http://nesdev.com/bbs/viewtopic.php?t=7727 already, where naruko has RE'd a pinout for n175 and n340, and a picture of n129. Also his blog at http://d.hatena.ne.jp/na6ko/. Unfortunately, I'm having trouble parsing what's being said through a computer translation.

Perhaps you could browse bootgod's database for pictures? There are some blob free namco chips there.

I could have sworn I looked through that and didn't see them. Oh well. The question about the N106 stands.

N106 does not exist as "N106".

The part number is C163. (Custom 163)

on this thread http://nesdev.com/bbs/viewtopic.php?t=8570 I documented the pinout for the chip, even.

Interesting, I've never seen a packaged 129 yet. Must be pin compatible with the 163 at least. Still have yet to see one labeled a 106, which all m19 games used to be referred as... Would be great to see those docs translated to english.

Regarding your PM about mapper 19/210 and mirroring, may as well post it here:

Games that use the 175 or 340 used to be marked as mapper 210 in DB. I recall Marty/Nestopia suggesting that the 175/340 were stripped down versions of the 163. Unfortunately a lot of the misc. registers in question reside in the same space part of the copynes BIOS gets mapped into, so I cannot test them. Though from what I can tell from naruko's docs, this might actually be the case.

Anyways, Marty later said they could all be emulated as m19 and he dumped m210 from Nestopia and I followed suit. All the 163 carts I've run into use software mirroring and all 175/340 carts use hard-wired mirroring. Probably wouldn't be any harm in changing them back to 210.

BTW here is a result set showing all m19 games in DB right now (w/ hardware info / pcb pic).
