Here's the pinout to a 4Mbit/*Mbit mask Rom used in SNES carts as I've
|
||||
deduced from various specs and actual testing.
|
||||
|
||||
1 A17 ------\__/------ +5v 32
|
||||
2 A18 | | *OE 31
|
||||
3 A15 A19 30
|

|

5 A7 A13 28

|

7 A5 A9 26
|
||||
8 A4 A11 25
|
||||
9 A3 A16 24
|

10 A2 A10 23
|
||||
11 A1 *CE 22
|
||||
12 A0 D7 21
|
||||
13 D0 D6 20
|
||||
14 D1 D5 19
|
||||
15 D2 D4 18
|
||||
16 GND |---------------| D3 17
|
||||
|
||||
The design approximates std EPROM/SRAM pinouts except for the upper address
|
||||
lines (A16-A19), and OE which sits where VPP or PRGM usually is for an EPROM.
|
||||
This pinout approximates Fujitsu's tentative mask ROM pinouts (a package
|
||||
called GAMEMEDC.ZIP seems to base itself on this and is consequently wrong).
|
||||
Nintendo uses Fujitsu chips in some carts, but from my testing and card-edge
|
||||
pinouts provided by other users, I conclude that Fujitsu must have modified
|
||||
the designs.
|
||||
|
||||
NOTE!: Card-edge pin #40, address line 15 (A15) is not used by any cart I've
|
||||
seen. And ROM pin #3 (see above) that I've determined to be A15 is connected
|
||||
to card-edge pin#41, labeled on many pinouts schems as A16..not A15!!!
|
||||
Would some one please verify this inconsistency.
|
||||
|
||||
PS: How many Megabits can the Snes address?

the rom to death and help from Norm/Yoshi/chp.

* As of this documentation 32MBit ROMs are the largest that

Nintendo currently uses. Rumors of a 40+ kart are around,

but cannot be verified.
|

|

* 8MBit ROMs are the most common in the entire library of
|
||||
SNES karts
|
||||
|
||||
* ROMs are always multiples 2, thus 2MBit ROMs are the smallest
|
||||
Space Invaders (c) Taito is a 2MBit ROM (Japan only)
|
||||
|
||||
* Easy way to calc rom size without a lookup table
|

CHECKSUM - 2 bytes Checksum of the bin
|

* Anyone know how the checksum is calculated for the ROM?
|

|

NMI/VBL Vector - 2 bytes - OFFSET 81FAh (lowrom)

OFFSET 101FAh (hirom)
|

|
||||
RESET Vector - 2 bytes where to start our code at - OFFSET 81FCh (lowrom)
|
||||
- OFFSET 101FAh (hirom)
|
||||
* 8000h is common for Low Roms
|
||||
|
||||
=[READING THE CORRECT BIN INFORMATION]==================================
|
||||
|
||||
The bin information can be found in 2 possible places,
|
||||
|
||||
a) End of the 1st 32K bank (Low ROM) (81c0h/w 512 byte header)
|
||||
b) End of the 1st 64K bank (HiROM) (101c0h/w 512 byte header)
|
||||
|
||||
You could use UCON's method (author chp).
|
||||
|
||||
The method is as followed:
|
||||
|
||||
UCON's method is to OR the Checksum and the Complement. If the
|
||||
resulting value is FFFFh, then we found the correct location of
|
||||
to extract rest of the data out. HOWEVER! This fails on several
|
||||
karts, such as Castle Wolfenstien 3D and Super Tetris 3 for example.
|
||||
|
||||
Reason being is that not all developers put the correct complement
|
||||
or bother even to implement it. I would suspect! That this maybe
|
||||
a ploy to keep other developers out of the bin, for if they can't
|
||||
find the reset vector, disassembling becomes a bit difficult.

BASELINE 2091 Presents The First Guide To Coding The SNES
|
||||
Guide and Source Code by -Pan-
|
||||
Released on 4/20/93
|
||||
|
||||
|
||||
Welcome to the first installment of "How to code SNES"
|
||||
This first volume will show you how to make a simple text intro. It uses
|
||||
mode 0 graphics with no DMAs (Horizontal or General) and is the simplest
|
||||
type of intro you can make. We're starting small so you can easily understand
|
||||
what to do. Other future volumes will contain other graphic modes,
|
||||
Horizontal DMA (HDMA, the SNES version of an amiga copperlist), General DMA,
|
||||
Interrupts, and a brief section on Sound. Originally we were going to release
|
||||
the full Super Famicom Programmer's Manual but believe it or not, this manual
|
||||
a pile of garbage. Contrary to the popular belief that we always had the
|
||||
manual, this is NOT true. The White Knight happened to meet a very cool
|
||||
guy at the CEBIT in Germany and has gotten the manual 2 weeks ago!
|
||||
Yes! What you have seen from us before was true coding. We started out
|
||||
by hacking and working our way to the top. We didn't wait until we bought
|
||||
a manual. In fact, the manual was sent to us for FREE! This book isn't
|
||||
worth paying for!
|
||||
|
||||
Let's clear up a few misunderstandings about that SNES manual!
|
||||
|
||||
1) This book does NOT teach you assembly language!!
|
||||
It would help if you knew a little before trying to code this machine!
|
||||
|
||||
2) This book was not written such as other reference guides you can find in
|
||||
a store, like Mapping the Amiga, or even Mapping the C64.
|
||||
It tells you barely and confusingly what the registers do. Period.
|
||||
|
||||
3) This book is about 148 pages long and that includes the Sound Section.
|
||||
Some have said it was the size of a phone book. Unless live in
|
||||
Mud Hole, Kentucky this is NOT the case!
|
||||
|
||||
|
||||
So much for the introduction. I personally feel that experience is better
|
||||
than a reference guide. Reading a text file does not give you the feel of the
|
||||
machine. In the included source file, you will notice that almost every line
|
||||
has a description of what it is doing. This is better than telling you the
|
||||
registers and letting you fiddle around. You know what it will do, and you
|
||||
can see it in action in the assembled output (also included). I suggest
|
||||
you examine the source code right after reading this brief introduction on
|
||||
how the SNES system operates.
|
||||
|
||||
The SNES runs on a 65816 processor. This is similar to the 6502, but many
|
||||
new instructions are available. You will use the most popular commands
|
||||
like LDA, LDX, STA, PHA, PLA, RTS, JMP.. etc etc. There are some new
|
||||
ones but we will get into that subject in the next volume as it is not
|
||||
very important right now.
|
||||
The 65816 is a 16 bit processor that does 24 bit addressing.
|
||||
You can load and store 16 bit numbers, as well as 8 bit. The addressing is
|
||||
is different than the 6502 in that it includes a bank. If you have coded on
|
||||
the C64 you know that the addressing on the C64 was from $0000-$FFFF.
|
||||
That is 16 bit addressing. 24 bit includes 1 extra byte. This one byte
|
||||
is the BANK number. The SNES memory is broken down into fragments of
|
||||
32k blocks each. They are addressed from $8000-$FFFF and are stored into
|
||||
banks sequentially. If you wanted to access the first ROM byte in memory,
|
||||
the address would be $008000. The first $00 is the bank number, the first
|
||||
bank you can access. The $8000 is the 16 bit address. All banks (unless in
|
||||
high rom 64k bank memory) start at $8000!
|
||||
Remember that you can not write ROM. If you have coded on a C64 you have
|
||||
written a routine that looked like this:
|
||||
|
||||
lda #$00
|
||||
sta $c000
|
||||
|
||||
You cannot do this! $c000 is ROM and you can not write to ROM!
|
||||
To write to ram, simply write to any address between $0000-$1fff.
|
||||
If you need more memory you will find plenty at bank $7e and $7f
|
||||
These 2 banks contain memory from $0000-$ffff. These 2 banks each contain
|
||||
64k ofram totalling 128k for your own use!
|
||||
If you need to write to these directly, just use the LONG STA command
|
||||
example:
|
||||
sta $7ec000
|
||||
|

This will write to bank $7e at address $c000!
|
||||
|
||||
Fair enough. This was only a brief lecture on how the memory works.
|
||||
|
||||
|
||||
The SNES hardware registers and how the work:
|
||||
|
||||
You will notice when looking at the source code something very strange.
|
||||
Some registers are written to twice in a row! This because some registers
|
||||
need more than one 8 bit info, such as the scroll X registers. In these
|
||||
registers you can enter any number between $0-$07ff, but they are written
|
||||
as two 8 bit numbers, one right after another.
|
||||
example:
|
||||
|
||||
lda #$07
|
||||
sta $210d
|
||||
lda #$00
|
||||
sta $210d
|
||||
|
||||
This writes #$0007 to $210d, plane 0 scroll x register.
|
||||
|
||||
Using 16 bit data storage will not work for this type of register!
|
||||
example:
|
||||
|
||||
lda #$0007
|
||||
sta $210d
|
||||
|
||||
This will not work because it will write #$07 to $210d, then a #$00 to $210e.
|
||||
|
||||
Another strange register is the self-incrementing register such as the VRAM
|
||||
address registers $2116 and $2117.
|
||||
After writing to $2119 (or $2118 in another setting) the VRAM address in
|
||||
$2116 and $2117 will be increased. You do not have to do it yourself.
|
||||
This can be seen in the Character set (font set) transfer routine in the
|
||||
source code.
|
||||
|
||||
|
||||
Introduction to Video RAM (VRAM)
|
||||
|
||||
The Super NES system has it own graphics processor. This requires its own
|
||||
ram to read/write graphics data. This ram can only be accessed through
|
||||
certain registers such as $2118 + $2119. To access Video Ram you MUST
|
||||
turn off the video or you must be in screen blank (horizontal or vertical).
|
||||
This is one of the downsides of the SNES.
|
||||
Video Ram allows the storage of map planes and tile graphics.
|
||||
VRAM is only 64k long and can not be used as regular ram. You can not
|
||||
program in it, it is a separate unit!
|
||||
|
||||
In this volume we show you how to make a text screen in Mode 0. There are
|
||||
8 graphic modes numbered from Mode 0 to Mode 7. Mode 0 is the most
|
||||
simplistic. It allows only 4 colors per tile, but allows all four
|
||||
planes to be used.
|
||||
|
||||
A normal video screen on the SNES is 32*32 tiles, which comes out to an
|
||||
even 1024 tiles. You can widen the screen but you still may only have
|
||||
1024 tiles. There are 2 parts to displaying a graphic on the screen.
|
||||
There is the tile graphic data which gives the tile its picture. Then there
|
||||
is the Map data. These are individually placed tiles placed on the screen
|
||||
to produce an image.
|
||||
|
||||
example:
|
||||
|
||||
BBBBB SSSSS LL
|
||||
BB BB SS LL
|
||||
BBBBB SSSS LL
|
||||
BB BB SS LL
|
||||
BBBBB SSSSS LLLLLLL
|
||||
|
||||
Notice that all the small B's are the same. These woulds be drawn as
|
||||
Tile Graphics. They all form together to create the large B image.
|
||||
These B's together would be the Map data. The same would go for the S and L.
|
||||
|
||||
This is enough info to understand the basics of this 2 color intro.

||||
