🧩🧠 This is a general-purpose memory-related function.

vdp_sync(mask=0, asset=0)

To switch between assets, vdp_sync can be used to load contents from an asset to runtime.

Parameters

• mask : mask of sections you want to switch:

Colorset Chunk  -> 1<<0
Character Chunk -> 1<<1
Sprite Chunk    -> 1<<2
Map Data        -> 1<<3

0 - will switch all the sections 1 | 2 | 4 - will switch only COLORSET, CHARACTER and SPRITE sections, for example

• asset : asset (0..n)

Description

Use vdp_sync() to restore runtime data from the assets. For example, if you have manipulated the runtime memory (e.g. by using vdp_mset), you can reset the active state by calling vdp_sync(0,0). This resets the whole of runtime to the contents of assets 0.
