I've searched pretty much everywhere I could understand (and even some of those sites in foreign languages) and can't figure out what's wrong with piKey. I have a PSP-1001 running 5.00 M33-6, a 4gb Memory Stick Pro Duo Magicgate and a Palm 3169WW Universal Keyboard. I've tried enabling all sorts of plugins and reinstalling piKey several times. It seems as though no matter what I try, piKey won't work. I'm trying to use it in DOSBox and ZX-81's PSPWrite.
I'm starting to get frustrated, can someone please help? 
UPDATE: I got it to work, halfway. I can open up the piKey test program and press keys, and it'll show me the input codes, but they're all wrong -- Spacebar is escape, ~ is enter, etc. This only works if I set the keyboard type to Targus. Changing the keymap .ini does nothing to fix this.UPDATE: I decided to just buy another keyboard, a Targus.
