I have tried at least four different versions of Air Zonk, including Japanese versions (PC Denjin), on multiple emulators for the PSP. I mainly use HuE, but have tried a few other emulators as well. Usually the game will freeze within a few seconds of the first stage. I haven't found any verified working copy while searching the internet, but you'd think at least one copy would work. Is this a known issue for the game? BTW, I haven't found a manual for HuE online. All I've been able to find so far is that I can save and load states by hitting L+Select. Is there any way for me to alter the configuration, like screen size?
