CaSTaway/PSP - version 002
------------

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

Assuming this second alpha works for you at all (it should!), I think you'll
enjoy it; full sound and joystick and mouse support, can pick from a small
number of disks so you don't need to rename all the time now, and shes full
screen. For games with a loader menu or that need text entry, an onscreen
keyboard is supported with most (but not yet all) ST keyboard keys.

I'll be fleshing out the GUI with more options, a scrolling disk list and
disk->database lookup very soon; expect savestates and all the usual emu
goodness soon!

- Get yourself a TOS.ROM before running the emu
- Get yourself a few .ST disk images too!

Alpha 002
---------
NEW: Basic disk picker (it works, but not fancy yet)
  o Lists .ST and .MSA files in the /PSP/GAME/ATARI_ST directory
  o Don't use MSA's yet.. they're screwy
  o Press 'X' to run the emulation
  o Press '()' (circle) to select a disk; you should always select a
    disk at this point, since if it runs without any disks it gets confused
    for now
  o Only put in 5 or less disks for now; lame, but I ran out of time and
    wanted you to have something to play with for the weekend (Spent days
    tracking down an obscure bug :/)
CHG: Mouse speed increased a bit; double-click and such should work
REM: TOS has to be called TOS.ROM (TOS.IMG seems not to work.. not sure why :/)
  o You need a TOS.ROM file; don't ask me where to get it.. ask Google or
    suck it from your Atari ST machine.
NEW: Full screen scaling with smoothing by default
NEW: Onscreen virtual ST keyboard
  o Use [SELECT] to toggle keyboard on or off
  o While present, left d-pad controls keyboard selection point and
    right d-pad X will push the selected key
  o Adjusted key hold duration and repeat duration to avoid million-presses

Alpha 001
---------

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!
