On the left is an overview of the Amiga's configured RAM areas, with detected bitplanes shown underneath. On the right is the detail memory view, showing the currently selected memory window.

Drag or scroll to move through memory, type an address in the $ field to jump, or select a bitplane from the list to inspect it in the detail view.

Bitplane detection

The bitplanes panel continuously tries to work out which memory areas are currently used as bitplanes by watching the Amiga's DMA and measuring the line-to-line stride. Detected areas are listed on the left, largest first. Graphics in chip RAM show up as recognizable images.

With auto-select enabled, the detail view automatically follows bitplane 1: whenever the guessed bpl1 area changes (for example on a screen or buffer flip), the view jumps along with it so you keep seeing the active image. Turn it off to stay parked at a fixed address.

Colors (access tracking)

Every RAM/ROM access briefly lights up in a color, then fades back to the gray cold palette. This shows which areas are being read and written right now, and by whom (chip, slow, fast RAM and Kickstart ROM):

Green = CPU reads, red = CPU writes, blue = blitter writes. Writes win over reads on the same cell. Note: CPU also fetches its instruction code from memory so these areas will also glow green.

Fade length

How many emulated frames an access stays highlighted before fading back to the cold palette. The fade freezes while the emulation is paused.

Slomo speed

How fast slow-motion single stepping runs: the delay between the frames it steps through. Lower = faster.
