Hi, Long time MAMEer/EMUer first time PPC owner (just finally upgraded from my Sony PEG-S320 PalmOS device) Here is some information on this device if Tehkmaster or anyone else is interested.

Key addresses
Record key= 0xC5
Scroller press= 0x86
Calander button= 0xC1
Task button= 0xC2
Home button= 0xc3
Contacts button= 0xC4
D-pad/Scroller button up=0x26
D-pad/Scroller button down=0x28
D-pad button left=0x25
D-pad button right=0x27

If you already knew that OKbut the documentation mentioned letting you know this info (Ya I actually read the docs! lol)
I noticed that another post mentioned that current ROMs used should be the "old" ver.36 final MAME roms is that true? Any idea why I get an error of

"Application MEGAMameCE3.exe has performed an illegal action...
Program:
MEGAMameCE3.exe
Exception:0x0000005
Address: 0000000"

I get this error on Rastan and gauntlet. Ms.Pac-Man and Donkey Kong play fine.
Also this is odd to me, If I have the ROM sets "puckman" and "pacman" then the game Puck-Man appears in the list but not Pac-Man(Midway) however if I delet the ROM set "pacman" then the game Puck-Man dissapears from the game list...oddd.
Anyhoo a dandy of a lil program you have hear one of the reasons I went PPC over anothe PALM device thanks for all the hard work.
