Skeezix has released the first Atari ST emulator for the PSP, heres what he posted:


CaSTaway/PSP
------------

Crappiest first alpha (for PSP). Don't expect much yet, except for updates
to come quite quickly over the next little while.

Although the emu is missing any form of finesse, it does run pretty well --
for many or most games, it'll run full speed with no frameskip (which is good
since I didn't implement frameskip yet During 'heavy math' operations it'll
run slower, so unpacking Dungeon Master takes a good minute or two probably..
but running Xenon 2: Megablast and it'll run a little too fast until I add
speed throttling.

REM: .ST disk images only (.MSA or zipped images not yet supported.)
REM: Default disks looked for: DISK_A.ST and DISK_B.ST -- you don't need
them if you just want to see TOS. If you want to boot a game without
picking in the (not yet existing disk picker, name it DISK_A.ST!
ex: /PSP/GAME/ATARI_ST/DISK_A.ST that is a copy of A_133.ST (Automation 133)
will fire up Xenon 2.
REM: You need an operating system; the file can be called either
TOS.ROM or TOS.IMG (doesn't matter, its just a filename); use TOS 1.02 US
for best results, but many others work (and many do not.)
REM: Stick files in /PSP/GAME/ATARI_ST
REM: ST-Low res works well; ST-Medium res works, but is fugly for now.
ST-High res not yet supported.
REM: Analog is for controlling the mouse motion
REM: Left D-pad for controlling joystick motion
REM: Square is left-mouse-button, circle is right-mouse-button,
cross/X is joystick fire

For now, Triangle hits '1' on the ST keyboard.. maybe can get into some
games (such as Xenon 2: Megablast). Right-trigger is 'Space', so should
get a few games going.

Needs: Throttling -- a little too fast sometimes; during high math its
likely slow (like loading Dungeon Master, though runtime should be fine.)
Needs: Fullscreen scaling
Needs: Disk selection menu
Needs: Frameskip selection (and other 'options' menu)
Needs: Etc etc.

Enjoy!
