Dev Menu (RSDKv3)

The Dev Menu is a debug menu included with RSDKv3, disabled by default. The menu includes several features useful for debugging games in the engine.

Enabling

BlitRSDKv3 Decompilation

The Dev Menu can be enabled by editing the game's GameConfig.bin file to set the default value of the Options.DevMenuFlag global variable to 1 (true).

The Dev Menu can be enabled by setting DevMenu to true in the settings.ini file, like so:

[Dev]
; Enable this flag to activate dev menu via the ESC key
DevMenu=true ; (1)!
; Enable this flag to activate features used for debugging the engine (may result in slightly slower game speed)
EngineDebugMode=false
; Enable this flag to force the engine to load from the scripts folder instead of from bytecode
TxtScripts=false
...

1. Make sure that the decomp is not running while editing settings.ini; otherwise, your changes will be reverted upon closing the decomp.
