MoonGBA – probably the fastest Game Boy Advance emulator for Windows Mobile platform made by Xiangpeng Chen -Freeware. Without sound enabled it works almost perfectly on BenQ E72 with 230MHz omap processor and ~20MB of RAM, on devices like HTC Blue Angel and HTC Universal its amazing!
Advantages:

• Really fast rom emulation
• Runs on slower PDAs/smartphones
• Portrait, landscape left/right + fullscreen, fit to screen, vga screen view modes + “antialiasing”
• Frameskip + frame speed settings
• *.sav files support
• Touch controlled pad (activated in settings)

Disadvantages:

• Only 3 save / load slots
• Not quite good sound emulation comparing to other emulators
• Noticed that it doesnt work on HTC Kaiser

Requirements:

• Windows Mobile 5.0 or later based device
• ~200MHz processor for comfortable playing without sound (depends on processor model)
• About 15MB RAM for loading 4/8MB roms; 20+ for loading 16MB roms
