Are there any other documents around that make light of the less common mappers such the ones by Irem, Konami, Taito, Jaleco, Nichibutsu etc? I swore that I found a site last month (may have been Japanese) that listed at least every Konami game and made sense of which games contained what "mapper" and how they were physically connected on a game by game basis, some of the Konami MMCs are apparently mapped differently on different games. I'm trying to be a purist here and it's a little hard when Konami iNES mappers consolidate multiple MMC into one "mapper" or split it into two. Anyways, I haven't been able to find this site again and I'm starting to think I dreamt it. Even so, I still desperately want information regarding which "mappers" which games actually use and an explanation of each MMC's registers. I'm not looking for only ASIC MMC but even ones composed of 74 series IC. Since Kevtris hasn't released his notes on these mappers yet and it's pretty clear I should avoid Firebug's doc, I'm lost. I'd be happy if anyone can point me to any documents regarding mappers not covered by Kevtris actually.
