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
02	Additive Alpha
03	Subtractive Alpha
04	Somewhat no alpha but with darker shade

Effect	Address (January 6th Update)	Default Parameter ID
Trail Effects	95EF3C	02

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

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

Material Opcodes

A list of material types are implemented in the EXE.

Material type parameters	Hexadecimal type	Description	Parameters	Example(s)	Notes
13 & 14	Byte	Source Blend Destination Blend	01 = Zero 02 = One 03 = Source Color 04 = Inverse Source Color 05 = Source Alpha 06 = Inverse Source Alpha 07 = Destination Alpha 08 = Inverse Destination Alpha 09 = Destination Color 0A = Inverse Destination Color 0B = Source Alpha Saturate	6A 05 6A 13 6A 06 6A 14	The 7th blend function is the same as with the 2nd blend parameter, but it produces bloom effect if used as a destination factor.

EXE offsets

These are a list of addresses that have codes that provide special effects to models and the interface.
