Main Article
EXE Editing
EXE Editing

The main EXE of the PC game release is slw.exe and it is in little endian. The RAM address pointer changes after launching the game or modifying it.

Materials Functions

Blend Parameters

Certain parameters that go to certain effects like Sonic's trail effects are stored in the exe rather than the .material files packed in the archives. These set the blending options according to the parameter loaded on the start of the level.

Parameter ID Blend Mode Result
00 and 01 Normal Alpha SLW Trail Normal Blend.png
02 Additive Alpha SLW Trail Additive Blend.png
03 Subtractive Alpha SLW Trail Subtractive Blend.png
04 Somewhat no alpha but with darker shade SLW Trail Dark Blend.png
Effect Address (January 6th Update) Default Parameter ID

Colors

Sonic Model Materials

Glossy Sonic Mode

To achieve a glossy look of Sonic the Hedgehog in the game, you'll need to hex edit the bytes provided in the address of the executable.

Address (January 6th Update) Original Bytes Replace With Result
45BA8E 0F 84 DB 00 00 00 90 90 90 90 90 90 Sonic Lost World Glossy Sonic.png

After that, you will need to jump or use spin dash in-order for it to take effect.

Sonic Trail Colors

The colors for the trail effects are located in the following addresses of the EXE.

Address (January 6th Update) Default RGBA Hex Type
BB3C08 00 00 FF FF Blue Sonic
BB3C0C 00 64 00 FF Green Sonic
BB3C10 FF 00 1E FF Red Sonic
BB3C14 6E 64 32 FF Super Sonic

The color parameters for the effects can be set by changing the code since Multiplayer isn't present on the Windows version of the game.

Address (January 6th Update) Original Bytes Replace With Byte Parameters (Offset 0x01)
4F094B 8B 82 6C 03 00 00 0C 00 90 90 90 90 00 = Blue
01 = Green/Lime
02 = Red
