CaSTaway/PSP Alpha Version Released (Atari ST on PSP)

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!

Shame SWOS never came out for Atari ST, but this is GREAT news!!!!!!

I loved the Atari ST, Best Atari machine ever. So many great games. sound very exciting if it's running full speed already!!! Can't wait till it has a good front end with disk swap options and full screen support. i'm very excited about this one!

It doesn't work for me. I have put TOS.IMG (1.02) in ms0:\PSP\GAME\ATARI_ST\ and a game in the same folder, but I just get a black screen. I tried to move the tos file to Castaways folder but it still doesn't work. Have any one successfully started this emulator?

EDIT: I've fixed the problem. It seems that the tos file must have the name TOS.ROM and NOT TOS.IMG. SuperCars runs perfect at full speed!!! I guess I have to play this ST version until UAE gets better.
