Release 005
-----------
FIX: Handle more than 250 disk images/savestates (up to about a thousand now ;)
NEW: Added goofy ST-like unpack effect at load time -
'unpack demo' for a few secs, wait a sec, 'black' and menu as normal
NEW: Can set throttle to 60Hz, 50Hz, or even 30Hz, or unthrottle
NEW: Added scaling menu, so you can specify..
o Scale 1:1 with centering
o Scale fullscreen with smoothing
o Scale fullscreen without smoothing

Release 004b
------------
NEW: Caching of the database lookups; having it re-scan the disk database every
time got on my nerves quick, so now it caches the lookups to memstick; as
such you only get the 'big hit' once, or whenever you copy over a pile of
new disk images. Subsequent loads will only check new disks, so the lookup
will be much faster each run.
o Side effect -- if you _rename_ files around, you might eventually need
to delete the STCACHE.TXT file as it would become inaccurate. But no biggy,
I doubt anyone will do that..”

This is a sexy build if I do say so myself..

CHG: When in joystick-on-analog mode, sensitivity is reduced a bit.. ie: I
found when pulling left I'd often get up-and-left or down-and-left as my
thumb isn't accurate enough; so I've altered it so to indicate a direction
you need to be further to the edge of the analog zone, so it more often
would detect straight-left when I wanted it.

CHG: New font for user interface; built a font importer package so I could
suck in truetype fonts easily, and am using a variant of Arial 14px for now..
should be much more readable and smooth (a little bigger and rounder.) I'm
pleased with my 'auto kern' system.. seems to work well for nice dynamic
spacing.. I just need to add auto-anti-aliasing sometime
- For each dialog, title font is bold and with drop-shadow

NEW: In menus, up/down works as normal; left/right will quick-scroll up
and down, letting you move faster.

FIX: Repeat timer prevents 'cursor mode' from repeating 'too quickly' ..
so using cursor mode for playing Dungeon Master, Captive etc should work
pretty well now

FIX: In game-list (output from database lookup) it shouldn't sometimes have
garbage in game names

NEW: New PSP launcher artwork - backsplash and icon by parobolee - thanks mate!
o Looking good I think!

CHG: Increase game list height, to show more games if lots in database

NEW: ST Games database right in the disk picker
o Database look up is done each time disk picker comes up; sort of lame..
should at least be cached within the emu runtime, and ideally between emu
runs.. but maybe next version
o Draws first 25 characters from game-list descroiptions, starting about
1/3rds of the way over in the picker display; should fit pretty well. To
get the rest of the listing, pick the disk and hit "look up in database" to
get the full listing line by line

NEW: When analog is operating the ST mouse, there are now two speeds build in..
ie: far-left is 'left 2px per frame' while half-left is 'left 1px per frame'.
Let me know if more degrees of speed are needed..

NEW: Frameskip is supported (though mostly not needed!) -- in the runtime
[start] menu, frameskip options are available. Some math heavy operations
will slow things down a touch, but generally the emu is fast enough.

NEW: Throttling is supported; in the main runtime [start] menu you can now
enable or disable throttle -- enablingmeans the system is slowed down to
approximately a real ST (north american, anyway); if throttle is off, try
running as fast as possible. The default is throttle is _on_

Tonnes of additions.. its really pulling together, and most anything you'd want is now present. Just need to fill in a few more little things, maybe flesh out the menu navigation options a bit, and add some config files.. but all the main goods like savestates and loadstates are all present now!

Alpha 003
---------
NEW: While emulation is running, hit [START] to bring up runtime options
o Disk Management -- lets you eject and insert a different floppy(s)
o Reset menu works -- lets you exit the emulator entirely, or do a
warm reset on the ST (ie: Try inserting some disks, then hitting
reset, and voila.. no need to exit emulator to swap disks.)
CHG: Turned brightness up a notch (shifted colour palette decoding)
o Med res and low res both
CHG: On-screen keyboard
o The 'selection' is alpha blended to darken the key; nicer than blacking
it out
o The keyboard itself will fade in and out rather than just toggling on
and off when you hit the [select] button
NEW: In addition to .ST disks, .MSA format disks are all supported; further,
either kind of disk can be in a .zip file and work fine. (As long as thats
the only file in the .zip) -- some .ST's will compress from 800k to 200k
in a zip file, so it could be worth it.
NEW: Added simple intro-screen so you know what version is coming up
NEW: Disk picker changes
o When you hit () to pick a disk, it'll ask you if you'd like to insert
it into drive A, or B, look it up in the database, or delete it.
o Insert into A, B, and delete now work
o Disk picker now allows you to have many disks -- it'll scroll; no more
than about a thousand disks for now (It shows .ST, .MSA, .ZIP and
.SS files)
o If no disk is chosen (like you hit X to many times), it'll warn you so
you know why nothing really exciting is going on
FIX: The mouse should work nicely; in 001/002 it might sometimes just not
work at all, but I've tried it in no-disks, and Dungeon Master and others
FIX: The key release and press mechanism has been fixed up a bit; when you
use the on-screen keyboard to press a key, it should get held down for
1/6th second and then released. If this is not sufficient, let me know
and I can increase its duration.. but that should be plenty.
NEW: Savestates/loadstates - you can now save a snapshot to SD card and
load it up later; far more useful than in-game-saving, and faster.
o Build a crude keyboard based interface to typing in a filename for SD card
o Savestate
- you name a filen "aaaa" and the emu compresses the system RAM (etc)
into a zipped file "aaaa.ss" (.ss denotes savestate)
o Loadstate (from the normal disk picker menu)
- pick a .ss file in the disk picker (as if it was any other disk); a
"load now" or "delete" menu will appear, so you can fire up the state
or just delete it
o Seems to work; I saved out a xenon2 savestate and loaded her back up;
use this to circumvent multi-disk or long loadtimes (Civilization and
Dungeon Master, I'm looking at you!)
NEW: Check for existance of TOS.ROM; if missing, show warning.
NEW: Games database
o When you pick a .msa, .st or .zip, it'll offer to insert it into the
drives; another option is to "look it up in the database", which calculates
a CRC on the disk and looks it up in a special database the GP32 users
helped create. If the CRC is found, a listing of games on that known
disk is shown.. otherwise, an error shows that its not in the database.

I hope you dig it!

Let me know what you think

version 002 2nd September 2005 Here

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

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!
