Like the first game, the engine for Lakers does not display the half-width apostrophe character(hex byte 27), as it uses that to indicate a call to a certain subroutine. Once again, we can change the value it checks for to an unused punctuation instead.
In REI2.EXE, replace the value at address BEF5 with the an unused punctuation such as "|" (hex 7C).
There is an error in the original that displays the wrong graphic for Flying Ema in the Database. The command "0f 1d 03 00 00 00 1a 24 00 2b 86 00 ff 00 00 00 00" before the Flying Ema description needs changed to "0f 1a 03..."
For the character bios in the intro, it "types" the character info pausing at predetermined points. When replacing the text with english, the pauses have to be manually repositioned.
The "cursor" position is written to 1a64:009c, first one is 04d8, 0550, 05c8, 0640, 06b8
[01f2] and [01f4] are used for something, a segment address it copies from the graphics plane and then copies back to the same spot?
13ca:17df starts the text for Star Laker sets [009c] to 04d8, pushes two numbers (a,b) to the stack calls to 48cc to draws the text from column b to column a (range 0-14 or 15), pushes 03 and calls 4a2f to pause and flash the cursor, adds 78h to 9c whenever it hits the end of a line
call 4b85 before to do the wipe fade in on the name and stats
rest of the Lakers set 9c to 04b0, 0410 for Blade Knight
13ca:1ab5 starts for Kungfu Laker, 1db3 for Judo Laker, 209e for Soul Laker, 239e for Bunny Laker, 26ca for Blade Knight
Search "c7069c00" in L2_OPEN.EXE to find the locations, b8xxxx sets ax to the value, 50 pushes it to the stack, 33c0 clears ax (set to 0000), e8xxxx calls relative to the current instruction

Lakers 2 uses the same file types as the first game, with the game scripts and data in BIN files, but the internal format is different for the REI2.EXE executable. There is separate executable for the games opening cinematic, L2_OPEN.EXE. It uses the same OZM format for graphics as the first game, but also uses OLH files for animations.

The BIN file extension is used for a couple different types of data files, be it scripting for the narrative portion or data for the battle scenes, and they do not all share the same format. The script files can have data before the actual script starts so the first two bytes is a pointer to where the actual script starts. Similar to the first game, REI2_CHR.BIN contains the character, equipment, and attack data and REI2_MES.BIN has the various lines of battle dialog. The BAT_xx.BIN files are just data for the battles and contain no text to translate, so I ignored those. The rest of the files use the instruction bytecode in the table below. The way it handles jumps and pointers is not entirely straightforward, as it stores them in a table of variables and calls them by index, rather than including them in the jump command directly, and those same variables can be used elsewhere in the script for other purposes.
| Opcode | Parameters | Function | Notes |
|---|---|---|---|
| 00 | xx yy zz | Conditional jump jnz | If the value at the memory address stored in variables xx and yy are equal, move read pointer to the address stored in variable zz. |
| 01 | xx yy zz | Conditional jump jz | If the value at the memory address stored in variables xx and yy are NOT equal , move read pointer to the address stored in variable zz. |
| 02 | xx yyyy zz | Conditional jump jbe | If the value at the memory address stored in variables xx and yy..., move read pointer to the address stored in variable zz. |
| 03 | xx yyyy zz | Conditional jump jnb | If the value at the memory address stored in variables xx and yy..., move read pointer to the address stored in variable zz. |
| 04 | xx yyyy zz | Conditional jump jb | If the value at the memory address stored in variables xx and yy..., move read pointer to the address stored in variable zz. |
| 05 | xx yyyy zz | Conditional jump ja | If the value at the memory address stored in variables xx and yy..., move read pointer to the address stored in variable zz. |
| 06 | xx | Jump | Move the read pointer to the address stored in variable xx. |

| 10 | xx yyyy zz aa | Draw text window | Draws text window at x position xx, y position yyyy*8, with a width of aa and a height of bb. Displays text ** until it reaces a terminating byte 00. Used for menu text and other places to draw text at an arbitrary screen position. |
| 11 | xx yyyy zz aaaa bbbb cc | ??? | |
| 12 | xx yyyy zz aa bb | Draw window | Draws image in a window and assigns the window index zz. |
| 13 | xx | Clear window | Clears window number xx and redraws what was behind it. |

| 17 | xx | ??? | Loads the BTLxx.BIN file at file index xxxx and begins the battle scenario. |
| 18 | ** | Text mode | Begins displaying text in the dialog box until the escape character "/E" is read. See the Text Format for more details. |
| 19 | xx yyyy zzzz aa bb cc dd ee (** 00) | Menu text | Display text at position (x*8,y), c= number of lines terminated by 00, used for menus and names in the the text boxes. |
| 1A | xx yy (...(yy*8 bytes)) | Set menu attributes? | |
| 1B | xxxx | Load music | Load music file at file index xxxx. |
| 1C | none | ??? | |
| 1D | xx | ??? | |
| 1E | none | ??? | |
| 1F | xx yy | Load script file | Load script file at file index in variable xx and set pointer to position in variable yy. |
| 20 | xxxx | Wait timer | Waits for xxxx to count down to zero. If it is FFFF, it will instead wait until the player hits a button. |
| 21 | xxxx | ??? | |
| 22 | xxxx yy aa bb cc dd ee ff gggg hh ii | ??? | |
| 23 | xx yy | ??? | |

Opcode 0F is the dialog text command. It displays text in the dialog box until it runs into the escape sequence "/E". The list of special escape sequences used is as follows:
| Sequence | Effect |
|---|---|
| /E | End of command |
| /CL | Clear the dialog box |
| /CR | Move to a new line(Carriage Return) |
| /HA | Wait for user input before continuing(Halt) |
