Descrizione Ninja Gaiden MMC1 to MMC3 Hack

Don’t think this is gonna be a 100% Gold Remake, it’ll have its differences. Extra battles (some’ll be optionals, tough but rewarding), Hoenn Pokemon (in every area, and hard to find) New areas, Remapped some dungeons (so your old guides wont work) , Extra recurring characters (some’ll hate you, some’ll help you)

Note that the hack is incomplete but feel free to enjoy the hack as-is.

Converting Ninja Gaiden from MMC1 to MMC3

RED BOLD INDICATES START OF MY ACTUAL FINALIZED PASTES. FOR NOW THESE ARE JUST MY RANDOM NOTES/TESTS.

MMC1 Bankswap for Ninja Gaiden is at $1C03A

MMC3 Bankswap at $1FFC8 = 0A48A9068D0080688D0180090148A9078D0080688D018060
20B8FF is new jsr bankswap routine

decyphering the rom, trickier than i predicted

$1F9A8 = A556 8DFFBF
$1F9BD = A559 8DFFDF
$1F9F9 = A201 8EFFFF

$1002F looks to be 1E into the $9FFF
chr mode = 4kb
prg mode = 16kb
$8000 swappable
vertical mirror

$56 = Change Entire Left PPU (deals with portion of hud, looks to be the Sprite 0)
$57 = PPU Page For Sprites
$58 = ???
$59 = Change Entire Right PPU (deals with all of hud)
$5A = PPU Page For Background 

hmm, put 60 at $101F9, and it will do the flash Act intro.

i might need to have the CHR routine located at $1FA2F, it needs to be constant.

sound engine initiation is located at $1F9F9, i need to put A903, then jsr to bankswap, and now the game has sound.

so this is what i have..............

$1FFC8 = 0A48A9068D0080688D0180090148A9078D0080688D018060
$1C03A = 20B8FF 60
$1C03E = 00000000000000000000000000000000
$1C05E = CA8E15404C62C000000000000000000000000000
$1F9A8 = left alone, this is the original ppu setup
$1F9F9 = A90320B8FF4CFBF900000000000000000000(enable sound engine)
$1FA10 = 20B8FF4C13FA00000000000000000000000000
$101F9 = 60000000000000000000000000000000000000(this enables the fly-by act sequence, and it also plays the cutscenes, like after the title screen)

At this point it's semi playable, but garbage looking, and no way to setup the chr

$1F5BC = A55A this is the ppu chr setup for ; $5A = PPU Page For Background 
$1F5D1 = A557 this is the ppu chr setup for ; $57 = PPU Page For Sprites
$1F9A8 = A556 this is the ppu chr setup for ; $56 = Change Entire Left PPU (deals with portion of hud)
$1F9BD = A559 this is the ppu chr setup for ; $59 = Change Entire Right PPU (and major portion of hud)

Need to create a new ppu engine since the old chr-rom is obsolete. tiles 00-FF represent 1 full page. There are total of 1F pages within Ninja Gaiden.

For the mmc3 ppu, 00-01 represents 00-7F tiles. 02-03 represents 80-FF tiles.

I have created a custom chr routine for Ninja Gaiden. Right now here is a bare setup for just the 2 registers $56 & $59

$1F9A8 = 2020FA 4CC2F9 000000000000000000000000000000000000000000000000000000000000000000000000
$1FA30 = A456 B9B0FB 8DFA07 B9D0FB 8DFB07 A459 B9B0FB 8DFC07 38 6901 8DFE07 B9D0FB 38 E901 8DFD07 38 6901 8DFF07 A205 8E0080 BDFA07 8D0180 CA 10F4 60
$1FBC0 (new mmc3 chr table) = 0004080C1014181C2024282C3034383C4044484C5054585C6064686C7074787C
$1FBE0 (new mmc3 chr table) = 02060A0E12161A1E22262A2E32363A3E42464A4E52565A5E62666A6E72767A7E
$1C062 = A900 8D00A0 4C62C0 (set boot up mirroring and $8000)
$1C06A = A980 8D01A0 EAEAEA (set wram)
$1FFBC = A900 8D00A0 60 (vertical mirroring)
$1FFC2 = A901 8D00A0 60 (horizontal mirroring)

With that going, the story mode shows all the right gfx, but i need to figure out where the text is being read from, cause that is not being read correctly, the text comes up as sprite pieces....

OK, $38A deals with the dialog chr. Cant do nothing with it though, idk how to make 2 separate chr routines go on without an irq engine...

Trying to find where the original mirroring is...
$1C controls the current nametable
$1C08B sets $1C as B0
$1F9D7 reads $1C and stores it into $2000

But what controls the mirroring...
A91E 851D 20E981(to 8DFF9F) soooo
CHR Size = 4kb mode
PRG Size = 16kb mode
$8000 swappable
Mirroring Vertical

idk, it looks like the A9 1E 20E981 is the culprit, but when i try to change it to 1F, i don't get the desired nametable change....I have to add it after it, like inserting a custom jsr...

$10032 is the first 20E981
$10456 is the second 20E981

ok, i found a table that has certain values in it, and some of them contain 1E & 1F, and if i change certain ones, it does change the mirroring!

Mirroring
-----------
$10F0F = Title Screen (1E)
$10F97 = Story (1F)
$127A5 = Ninja Gaiden Act - #
$10179 = (within asm) Start Level (1E)
So i'm doing more research, $10EF0 - $10F0B loads a 1C byte table, with 2 bytes each, low/high addresses, and from the starting address, it looks to be the 4th byte as the mirroring/$8000-$9FFF value, but that's from the title screen so it may be different for other things....

The asm from $1068F-$1069C is what is loading the indirect address values from $0A, that is getting the mirroring byte within all that other data, so maybe when this string of asm is finished, i should setup some kind of special mirroring table? or, do some checks of 1E/1F, and have it branch to the appropiate mmc3 $A000 mirroring setup?....And most likely do the sae for the 20E981 parts as well.

$1002E = A91E 851D 20E981
$10453 = 8C8503 20E981
$10178 = A91E 20E981

Again, from MMC1, here is 1E/1F being stored into $9FFF	
CHR Size = 4kb mode		;mmc1 $9FFF	;mmc3 $8000
PRG Size = 16kb mode		;mmc1 $9FFF	;mmc3 $8000
$8000 swappable		;mmc1 $9FFF	;mmc3 $8000
Mirroring Vertical		;mmc1 $9FFF	;mmc3 $A000

add maybe A980 8D01A0

20ACFF = vertical mirroring
20B2FF = horizontal mirroring

OK SO HERE IS THE FIXED MIRRORING
$10032 = 20E981
$101F9 = A900 20ACFF 60
$10178 = A900 20ACFF
$10456 = 20E0BE
$13EF0 = C91E F004 C91F F006 A901 20ACFF 60 A900 20B2FF 60

So with these changes so far, the title screen, story, ninja gaiden act - #, all work and appear correctly. 

NOW, it is the in-game play that is horrifficly screwed up.
