Here are Disch's original notes:
========================
= Mapper 096 =
========================
Example Games:
--------------------------
Oeka Kids - Anpanman no Hiragana Daisuki
Oeka Kids - Anpanman to Oekaki Shiyou!!
Notes:
---------------------------
These games use the Oeka Kids tablet -- so you'll need to add support for that if you really want to test
these.
These games use 32k of CHR-RAM, which is swappable in a very unique fashion. Be sure to read the CHR Setup
section in detail.
Registers:
---------------------------
I'm unsure whether or not this mapper suffers from bus conflicts. Use caution!
$8000-FFFF: [.... .CPP]
C = CHR Block select (see CHR Setup)
P = PRG Page select (32k @ $8000)
CHR Setup:
---------------------------
This mapper is tricky!!!
Firstly, this mapper divides the 32k CHR-RAM into two 16k blocks (above 'C' bit selects which block is used).
The selected pages (including the fixed page) are taken from only the currently selected 16k block.
$0000 $0400 $0800 $0C00 $1000 $1400 $1800 $1C00
+-------------------------------+-------------------------------+
| **See below** | { 3 } |
+-------------------------------+-------------------------------+
But that's the easy part. This mapper does a very, very cool trick which watches the PPU address lines to
effectively "split" the nametable into 4 smaller sections -- thereby assigning a different CHR-RAM page to
each section. This allows **every single tile in the NT** to have a unique tile graphic!
Long story short:
A nametable spans from $2000-$23BF ($23C0-$23FF are the attribute table).
The mapper breaks the NT up like so:
$2000-20FF = use CHR page 0
$2100-21FF = use CHR page 1
$2200-22FF = use CHR page 2
$2300-23BF = use CHR page 3
the other nametables at $2400, $2800, $2C00 are broken up in the same fashion.
Long story long:
PPU Address lines are modified as the PPU fetches tiles, and also when the game manually changes the PPU
address (via the second write to $2006 --- or by the increment after read/writing $2007). The mapper
monitors every change to the PPU Address lines, and when it lies within a certain range, it swaps the
appropriate CHR page in.
It will only swap CHR when the address falls between $2000-2FFF (or mirrored regions like $6000-6FFF,
$A000-AFFF, $E000-EFFF). $3xxx will not trigger a swap.
When in that range, it checks to make sure the address is not attribute tables ((Addr AND $03FF) < $03C0).
Note I'm not 100% sure if the mapper really does this or not. It's very possible that attribute fetches will
also swap CHR... this would not really disrupt anything other than making the game be more careful about its
PPU writes.
When all that checks out, bits 8 and 9 (Addr AND $0300) select the 4k CHR page to swap in to $0000.
Note that the mapper does not distinguish between PPU driven line changes and game driven line changes.
This means that games can manually swap the CHR page by doing specific writes to $2006:
LDA #$20
STA $2006
STA $2006 ; Addr set to $20xx -- CHR page 0 selected
LDA #$21
STA $2006
STA $2006 ; Addr set to $21xx -- CHR page 1 selected
And in fact, games would HAVE to do that to select CHR, since that's the only way to fill CHR RAM with the
desired data. So make sure your emu supports this.

Notes:
---------------------------
Swapping is really simple -- the thing that is funky is the register range/mask. $5000 and $D000 will access
the register, however $5100, $5200, etc will not.

Example Game:
--------------------------
Reset Based 4-in-1
Notes:
---------------------------
This mapper is very, very unique.
It's a multicart that consists of four NROM games, each with 16k PRG (put at $8000 and $C000) and 8k CHR.
The current block that is selected is determined by an internal register that can only be incremented by a
soft reset!
I would assume the register is 2 bits wide? Don't know for sure.
