I've found "TKO Boxing (VS)" writes to $8001. See code below. It looks kind of strange? I can't find any document behaviour for this. Mapper 151 docs has vanished from NESDEV Wiki aswell (or if not, it's very well hidden)..
Code: Select all
LDA $06F2 = #$00
STA $8000 = #$0F
LDA $06F4 = #$00
STA $8001 = #$09
LDA $06F3 = #$00
STA $8000 = #$0F
LDA $06F5 = #$00
STA $8001 = #$09

Sure looks like it's there to me:
http://wiki.nesdev.com/w/index.php/INES_Mapper_151
That said, where did you expect to find it? It's already linked to by the Mappers page and the Vs. System page.
Anway, that mapper write sequence is definitely not VRC1. TKO Boxing is one of the Vs System games that uses Namco's 108. It should be mapper 206.

If you see most mapper port writes going to $8000 and $8001, it's one of
these.

Also the first hit from Google for "mapper 151".

I expected some kind of memorymap for mapper 151 on the wiki..

All I saw was "This mapper is a duplicate of mapper 75. See the page about VRC1" where there's a
memory map.

Doing another port, orbit?
Honestly, having to buy NES Open Golf cartridges over and over just so I can make personal copies of all of your hacks is going to make me poor! lol
Oh I noticed you have a "VIP" section. I want some of that action.

Good way to support oRBIT2002 work. I like having an early preview of what he's doing.

TKO Boxing (ported to mapper 4) is already available on my website, now for everyone.

Did you use any of the features of the MMC3, or is it still compatible with the Namco 108?
