Inside AozoraMD

Emulation, inspection and display
01

AozoraVision BETA

An optional shader for a remastered look: upscaling, less dithering and banding, and reconstructed transparency in checkerboard effects. Recent work improves artwork protection and lettering. Results still vary by game and scene.

02

Hardware timing

CPU, video and audio share a master-clock timeline. The VDP models fetch slots, FIFO and DMA timing for raster effects and bus contention.

03

See what the machine is doing

Inspect CPU execution, memory, VDP layers and graphics in the built-in debugger. Save states and input recording help reproduce a problem.

04

Rewind, saves and controllers

Rewind, save states, cheats and configurable controllers. Choose raw output, CRT, AozoraVision or Hybrid, with OpenGL and Vulkan rendering on desktop.

Recent development

Merged changes; build availability below
Sound
YM2612 synthesis timing, phase modulation, envelope and native output corrections.
Video & CPU
H-counter tables derived from hardware timing, revised 68000 divide timing and documented SVP PMAC behavior.
AozoraVision
Improved artwork and lettering preservation. The first launch now explains the shader and lets you choose whether to use it.
