m Document PPF behaviour
Line 279: Line 279:
Display transfers are performed asynchronously, so after requesting a display transfer you should wait for the PPF interrupt to fire before reading the output data.

Some color formats seem to require specific input / output sizes when performing a display transfer, doing an RGB5A1->RGBA4 display transfer would never fire the PPF interrupt with a 32x32 buffer, increasing the buffer to 128x128 made it fire correctly.
The minimum supported dimension for output is 64x64, anything lower will hang the engine.
