PS2PSXe Public Preview - 模擬器

http://psx-scene.com/forums/showthread.php?p=493243#post493243

PS2PSXe Public Preview is released. PS2PSXeis a PS1-Emulator for the PS2 and
should be able to run PS1-Images from all devices (CD/DVD, HOST/LAN, HDD).
This is the first Homebrew-PS1-Emulator released for the PS2.


So as I wrote. Public PS2PSXe preview. Only command line version attached.
Unfortunately I wasn't able to get current sources to work properly (I'm
halfway with some major changes and it will take awhile to complete them).
The one attached you can consider as "the last one that actually works", or
simply rev168.

Now all the necessary stuff.

The emu supports both PAL and NTSC display, but I REALLY RECOMMEND leaving
the default PAL output. Why? Well, it's the only mode I use. Many fixes were
made to make PAL games show less glitches in PAL mode... When you switch the
display to NTSC it most often will show more glitches.

The PAL scph7502 bios is recommended to run games.

PAL games are recommended due to two simple reasons:
1. PAL games require only 50fps to be at 100% speed (NTSC games require 60,
so PAL games are easier to emulate).
2. PAL games should look nice when using PAL display mode... NTSC games will
always look much worse.
(well, I live in Europe. It's PAL region, so everything has been coded with
PAL games and PAL TVs in mind. Actually, the option to switch display into
NTSC mode has been added in rev163... so no fixes for that)
So use NTSC display mode only if your TV doesn't support PAL (yes I know this
sucks... Most TVs in Europe nowadays support NTSC... On the other hand, most
TVs in US do not support PAL... What a crap...).

Many of the parts of the emulator (like cue/ccd parser) have not been
changed/updated for few years (the time I created them in 2007 or so). I
focused on the most important parts of the emu... Once the time comes,
everything will be replaced by proper code rather than some temporary
solutions.

You shouldn't experience any problems launching it if you know what you're
doing... Otherwise it might crash before even showing you anything.

The emu doesn't provide any drivers or modules other than the parts of the
emu itself. But thanks to this it supports any devices that you will load
modules for. I've tested it with internal hdd, usb, lan, dvd and even ps2 mc.
I recommend using internal hdd or lan (host device). You can use usb, but the
asynchronous cd plugin is tweaked for high bandwidth media... So when using
with usb, some stuttering might occur here and there.

There is no real requirement for the modules present before the emu is
launched except one. The emu REQUIRES IOMANX module to be loaded before
launching it (older PS2link versions were loading it by default, but you will
have to load it manually for newer ones or change it and recompile it).

Default ps2client versions will always truncate the files opened for writing
and reading (even if O_TRUNC is not specified). Use the one from uLE or just
change it by yourself).

Now the options:

-cdimage=PATH
Path to the cd image. 2352 bytes/sector images supported. CUE and CCD
cuesheets are supported. Multiple tracks in ccd/cue are supported but only if
all tracks are in a single file (no multiple files). For multiple files just
point to the first track (it contains the data). PATH can be either relative
to ps2psxe executable or full path.

-exepath=PATH
Launches PSX exe file (for intros, demos and such).

-bios=PATH
Bios path (bios/scph7502.bin by default)

-digitizepad
Internally switches pads into digital only mode (visible to PSX code). If you
then manually enable analog mode (small analog switch at the center of the
pad), then the left analog stick will act as D-PAD and right analog stick
will act as R1/L1 horizontally. It's a nice features for games that do not
support analog sticks at all (like FF7)

-spfix
Stack pointer fix. Try it if something goes wrong. It might be able to fix
some games. It disables one of the optimizations (not many games make any use
of it anyway)...

-xoff=OFFSET and -yoff=OFFSET
Positions the screen on TV. You can use it to correct the image position if
your TV leaves eg. black bars at right or left side.

-sub
Enables subchannel support. It is really necessary only for libcrypt
protected games... For two years or so not even for them. It's kind of
obsolete as the emulator has automatic patch for libcrypt, so unpatched games
like FF9 PAL will work even without subchannel data. The subchannel file has
to have the same name as the img/bin/ccd/cue, just with the extension being
.sub (so if the image is ff9pald1.cue, then the subfile is ff9pald1.sub).
It's not really necessary anymore.

-excep
Disables some exception stuff. Use it if a games experiences problems. I
believe this one should not be necessary anymore, but I left it... Didn't see
a game that would need it in year or so.

-4ever
Disables most of the automatic libcrypt patches (not all of them though).
It's there just for testing, really. You won't have to use it until you want
to test subchannel file support.

-32bpp
Switches into 32bpp mode. I really RECOMMEND using it unless the game has
texture problems (clut problems to be exact). It's not default only because
it's not native PSX format . So use it unless it causes problems.

-nofps
Disables resolution/mode/fps display (the yellow crap at the top)

-nosprtf
Disables filtering for sprites. (2d images, though not all 2d images are
sprites). Needed for 2d backgrounds in many games (a must for all final
fantasy games - all ff games).

-nopolyf
Disables filtering for all polygons that are not sprites .

If you specify both -nosprtf and -nopolyf, filtering will not be used at all.

-nodith
Disables dithering in 16bit mode.

-ntsc
Switches display into NTSC mode. DON'T use it unless you really have to.

Savestates are screwed at the moment (search the information in the other
ps2psxe thread - I posted the reason a month or so ago).

Use (l1+l2+r1+r2+triangle+circle) to save screenshot in "snap/" directory -
always using executable (slesxxxxx) with counter (always checking for files
that are already there, so it doesn't overwrite files if used in multiple
sessions). Screenshots are saved in tim2 format.


(now some info taken from a mail I've sent some time ago to dlanor) Because
the gpu doesn't yet support offscreen drawing nor drawing on the same buffer
that is displayed, quite often instead of menus (even the fps counter may
die, but everything will work once the correct button is pressed), black
screen will be displayed. You will have then to either try you luck by
pressing common buttons (start, x, o) or to check how it in fact looks on
some other emu and then make the choice. Movies should be displayed now in
most of the cases, but sometimes all you will see is a black screen... Wait
or press start/x/o to skip it (it's not that often, it usually works). Some
things are just really hard to do in hardware accelerated gpu... I'm not sure
why yet, but the emu has a tendency to freeze for few seconds from time to
time (quite rare actually), so don't worry if it seems to freeze... Just wait
and it should unlock (unless it takes more than 10 seconds, then it is a
complete freeze).

Do not bother to report glitches and bugs. I know about them. You won't help
this way. This is PREVIEW, not a public beta for testing. Either use it or
not... It's as simple as that.
