Welcome to the Bionic Commando ROM Hacking Document. This document will provide you with all the information about the internal workings of the Bionic Commando and Top Secret ROMs.
Version 1.1 - Added an enemy listing, and a large amount of decompiled code. Check the editor for a new palette editor!
1.1 - Enemy listing, lots of decompiled asm.
1.0 - Initial release
This document has been compiled in order to allow fans of the Bionic Commando and Top Secret the ability to alter and adjust the game in order to improve, expand, and continue the legacy of the game. ROM hacking, although painfully time consuming, can be a rewarding experience which we would like to share with the rest of the gaming community. This document gives much of the nessesary information to create game editors. For those of you who have never hacked before, you'll soon realize that the rush you feel when you find out something new in a ROM is quite euphoric.
Fans of Bionic Commando and Top Secret have been the backbone for gathering information for this document. The following people have contributed.

Because of the difficulty in hacking ROMs, we're always on the look out for fresh minds willing to figure out new information. If you're already familier with ROM hacking take a look at section 5.0, Most Wanted Information. This will show you game information that we're looking for. Of course, if you want to look for other things, feel free. The more we know about the game, the better.
If you've never hacked a ROM before there are many documents that can teach you the basics of hacking a ROM file.
NOTE: Because of game differences, many of these offsets don't work in Top Secret.
00000-0000F - NES Header
00010-000EF - Screen Usage Pointer for each Room
Each Room is built up of 8x8-structure screens, and there are data for where in the rom to load screens for use in each room. Each Screen Usage Pointer is 16-bit refering to where to start reading Screen Usage Data. These 16-bit pointers are in real NES memory space adresses, to get the rom adress, subtract $80 from the high byte, and add $10 because of the NES header.
000F0-004B7 - 16-bit Screen Usage Data
In the room's Screen Usage Data, each 2 byte couple points to where in the ROM to pick Screen Data for each Screen in the Room. To get the actual ROM adress, do the same as above, subtract $8000 and add $10. For the info, if a pointer's value is above $BFFF, the rom will switch to 16k bank #1, subtracting $40 from the high byte, and using that as the pointer. If you're not into asm, dont worry about it. If both bytes are $FF, it means to stop setting up the screen queue. Not sure if there's actually any limit for how many screens you can use in a room.
004B8-0060F - ??? This stuff remains a mystery. It's not asm, it seems more like a piece of half-compiled source code, ready to be assembled into nes binary. Check it out and feed your imagination. 00610-0060F - Screen Data Readen from based on $F0-4B7. Very simple data. Each byte defines wich 32x32-pixel structures used to fill up one Screen. Each room has a different set of structures. The structure's properties is defined in the Structure Data.Bank 1 (04010-0800F)
Misc Map room chunk layouts 04916 - Comm Room 05B98 - Comm Screen 05C18 - Neutral Zone Room 06010-06011 - Pointer to "Palette Pointer for Each Room" 06012-060F1 - CHR Load Data Pointer for Each Room In this case, subtract 4 from the first nibble and add $10 to get correct adress. 060F2-07199 - Tile Load Data Each structure in a screen is built up of 4 blocks. A TileBlock is a 16x16 pixel tile that uses 4 tiles in the Pattern Table. Each tile load data chunk uses 80 bytes. 64 of these dectermines where in a ROM bank to load the 4 tiles for each TileBlock (4 tiles in the Pattern Table), and 16 additional bytes with 4-bit data to select the $4000 byte ROM-bank to load tiles from, and hit bits let's you flip the TileBlock Horizontally. 0-3F: CHR Pointers for each TileBlock Each byte points to a 4-tile chunk (for a TileBlock) in the ROM bank. 40-5F: 4-bit effect/bank data for each TileBlock 4-bit effect data: -HBB || |+$4000 BG-CHR Bank +Horizontal Flip Flag If the Flip Flag is set, the whole TileBlock (as a whole 16x16 tile) is turned Horizontal at load. The two last bits, bit 3 and 4, makes an 2-bit value telling wich $4000 bank in the CHR to load from. So, one can say that the whole CHR Pointer to a TileBlock is 10-bit like this: DDPPPPPPPP Where DD is the 2bit CHR Bank and PPPPPPPP is the other CHR Pointer data Here's a formula to calculate the Tileblock CHR's offset in the ROM: $ROMAddr = ($10010 + ([BG-CHR Bank] * $4000) + ([CHR_Pointer] * $40)) 0719A-07279 - Palette Pointer for Each Room Subtract 4 from first nybb and add $10 to get the address. 0727A-0790F - Room Palette Data NOTE: Palette data has both BG and Sprite Palettes for each room. ($20 bytes) The background color is defined by the 16th byte (first byte of the Sprite Palettes) 07910-0800F - Introduction scene ASMBank 2 (08010-0C00F)
08010-08011 - Offset of "Structure Data Pointer for Each Level" 08012-081D1 - 4-byte Screen Layout Data for each Room Each room has 4 bytes of data here. The two first is actually yet another 16-bit pointer, pointing where to read the rooms Screen Layout. The other two i'm not sure of, maybe they have something with the rooms screen size to do.. at least it has something with the layout of screens to do. 081D2-084D8 - Screen Layout Presets "Screen Usage Data" tells where in the ROM to pick up the Screen Data, this data actually has the order of those loaded screens. Each screen can be used several times also. One byte for each screen. 084D9-085B8 - Structure Data Pointer for Each Room 085B9-0880F - ??? More seemingly unused data.Bank 3 (0C010-1000F)
08810-0EC0F - Structure Data There are 256 structures read for one Room, and each of them has 7 bytes. Structure data is banked with $800 bytes for each Room. This data is laid out in 7 and 7 bytes, so $700 bytes is used, the last $100 bytes is filled with 0. 0: Block0 4-tile start offset 1: Block1 4-tile start offset 2: Block2 4-tile start offset 3: Block3 4-tile start offset 4: Structure Palette Attributes 5: Block 0 and 1 4bit block type 6: Block 2 and 3 4bit block type 0EC10 - Some ASM 0ED7B - Enemy Data Pointer for each Room (Yay! :D) 0EE5B-0F6D5 - Enemy Data Enemy Data goes like this for each enemy: 0: Enemy ID (See Enemy Table for full list) 1: X Position 2: Screen X 3: Y Position 4: Screen Y If byte 0 is $FF it means end of room's enemy data, else more enemies is initialized. 0F6D6-0F6DF - Empty $FF's 0F6E0-0F7BF - Room Special Event Data pointers 0F7C0 - Room Special Event Data This has to be figured out by time. The first byte seems to alter the frequency of the event, second byte; the event ID. 0F8F7 - Room Enemy CHR Load Data Pointers 0F9DB - Room Enemy CHR Load Data 0FBC5 - Sprite to PPU loading tables ex: 0080 00 00 9D 308A ... | | | |_pointer to $10A30 (10A40 in Rom) | | |_ stop at 9D in PPU ? | |_Start filling PPU from Line 0 |_pointer to $10000 (10010 in Rom) Enemy data starts at $EE5B (rom)Bank 4-9 (10010-2800F)

This section gives detailed information about how data table are setup in the ROM.
Map Information Maps are broken up in screen. Area 1's exterior is a good example. It is 5 screens wide and 3 screens high. This means 15 screens. A screen is 8x8 chunks. A chunk is 4x4 blocks. A block is 4x4 tiles. A tile is 8x8 pixels. Area 1 exterior is odd. There is a default screen which starts at $610 and is $40 bytes long. (This is the sky.) The rest of the map's screen are at $B50 - $DD0. Each is $40 long. The map layout looks like this: +-----+-----+-----+-----+-----+ |81EE |81EF |81F0 |81F1 |81F2 | | 610 | 610 | 610 | 610 | D50 | | | | | | | +-----+-----+-----+-----+-----+ |81F5 |81F6 |81F7 |81F8 |81F9 | | B50 | BD0 | C50 | CD0 | D90 | | | | | | | +-----+-----+-----+-----+-----+ |81FC |81FD |81FE |81FF |8100 | | B90 | C10 | C90 | D10 | DD0 | | | | | | | +-----+-----+-----+-----+-----+ The pointer for the screens starts at 81EE. Each byte is the lookup of the screen.3.3 How Sprites are Handled
