Dear PS2 ScummVM enthusiast user,
|
||||
|
||||
here you will find the latest and the greatest PS2 backend ever!
|
||||
|
||||
|
||||
*** Release Notes ***
|
||||
|
||||
Released 2 builds: SCUMMVM.ELF and SCUMMVM-S.ELF. The latter has engine
|
||||
modules statically linked into (that's what the "-S" is for), the former
|
||||
uses dynamic modules (uncached). The dynamic one is much faster to start
|
||||
and has more resources available for the games. The catch is that games
|
||||
detection, when you are adding a new one, is painstakingly slow...
|
||||
(as it needs to load, test, unload the plugins one by one).
|
||||
|
||||
Until we have an optimization for that in place I would suggest you add
|
||||
new games with "SCUMMVM-S.ELF", and when you are done adding you then
|
||||
play them with "SCUMMVM.ELF", as this will give you the best of both.
|
||||
|
||||
We no longer have a separate ELF build with hdd & net adapter disabled,
|
||||
as we now do it in the smart way, allowing users to disable it in their
|
||||
ScummVM.ini. See under in "Configuration" for details.
|
||||
|
||||
We also have an improved Makefile.ps2 in ps2 folder which will allow
|
||||
you to create: static, dynamic, profile and debug build version.
|
||||
|
||||
You can now also cleanly compile using "configure" and specifying:
|
||||
|
||||
./configure --backend=ps2 --host=ps2 ...
|
||||
|
||||
|
||||
*** Installation ***
|
||||
|
||||
Some media drivers require all capitalized letter, so to be on the
|
||||
safe side store the files (SCUMMVM.ELF and *.IRX) in upper case.
|
||||
|
||||
Here comes a full list of the required *.IRX (don't worry they are all
|
||||
provided pre-compiled in the binary release ;-)
|
||||
|
||||
IOMANX.IRX
|
||||
FILEXIO.IRX
|
||||
CODYVDFS.IRX
|
||||
SJPCM.IRX
|
||||
USBD.IRX
|
||||
USB_MASS.IRX
|
||||
PS2MOUSE.IRX
|
||||
RPCKBD.IRX
|
||||
POWEROFF.IRX
|
||||
PS2DEV9.IRX
|
||||
PS2ATAD.IRX
|
||||
PS2HDD.IRX
|
||||
PS2FS.IRX
|
||||
PS2IP.IRX
|
||||
PS2SMAP.IRX
|
||||
PS2HOST.IRX
|
||||
|
||||
Make sure they are all stored in the folder that contains your SCUMMVM.ELF!
|
||||
|
||||
If you are starting ScummVM from CD/DVD then it will look for ScummVM.ini
|
||||
a ScummVM.ini on the media folder from where you started SCUMMVM.ELF.
|
||||
|
||||
Notes:
|
||||
|
||||
- depending on the media you install Scummvm/PS2 onto, it might be
|
||||
picky about files cases, so I'd leave those *.IRX uppercase and
|
||||
scummmodern.zip lower ;0)
|
||||
|
||||
- make sure you selected a save path before you start playing!
|
||||
|
||||
- we added PS2IPS.IRX in case you wanted to test a debug build
|
||||
(use Makefile.gdb)
|
||||
|
||||
|
||||
*** Configuration ***
|
||||
|
||||
There is now a [PlayStation2] section in ScummVM.ini which can be used
|
||||
to make your wildest dreams come true ;-)
|
||||
|
||||
It accepts these entries:
|
||||
|
||||
tv_mode = [pal] [ntsc]
|
||||
gfx_mode = [mode number] [*]
|
||||
hdd_part = [partition name] [disable]
|
||||
net_addr = [PS2 IP addr] [**]
|
||||
usb_mass = [0] [disable]
|
||||
|
||||
[*] Currently supported gfx modes are:
|
||||
|
||||
# 1 -> SDTV progressive (NTSC: 224p / PAL: 256p)
|
||||
# 2 -> SDTV interlaced (NTSC: 448i / PAL: 512i) <- default
|
||||
# 3 -> EDTV progressive (NTSC: 480p / PAL: 576p)
|
||||
# 6 -> VESA (640x480@60)
|
||||
|
||||
If no tv_mode is specified it will be autodected based on PS2 model.
|
||||
|
||||
The non-interlaced (progressive) modes look much better and sharper.
|
||||
You can check the difference starting COMI and choosing About from
|
||||
the GMM (press "start" then choose "about"). You can easily see the
|
||||
difference between progressive and interlaced in scrolling text.
|
||||
|
||||
You can use mode 6 (VGA 640x480) if you are connecting your PS2 to
|
||||
a RGB monitor. Some TVs also supports this signal.
|
||||
|
||||
We also do some bad-ass things, like detecting the BIOS version and
|
||||
setting the GS registers by hand, for console models where a mode
|
||||
is not supported ;-)
|
||||
|
||||
If SCUMMVM.ELF hangs at start for you try disabling the adapter by
|
||||
setting in ScummVM.ini
|
||||
|
||||
hdd_part = 0
|
||||
net_addr = 0
|
||||
|
||||
You can now also choose the hdd partition used for ScummVM games
|
||||
(default "+ScummVM") passing it as an argument to hdd_part:
|
||||
|
||||
hdd_part = MyPartition (witout the "+")
|
||||
|
||||
If you have an adapter with hdd & net, but you don't use them you
|
||||
can just set both to 0 to disable, and have a leaner and meaner
|
||||
ScummVM booting much faster!
|
||||
|
||||
[**] TODO
|
||||
|
||||
*** Remote ***
|
||||
|
||||
You will need "PS2IP.IRX", "PS2SMAP.IRX" and "PS2HOST.IRX" drivers too
|
||||
in the folder where you are starting SCUMMVM.ELF if you want to use
|
||||
the remote capability.
|
||||
|
||||
The IP 192.168.1.20 (ps2link default) is hardcoded in the source as
|
||||
"netArg" in irxboot.cpp, feel free to modify it to match your network
|
||||
configuration.
|
||||
|
||||
In a future release you will be able to set in ScummVM.ini using
|
||||
|
||||
net_addr = xxx.yyy.zzz.www
|
||||
|
||||
If you are starting SCUMMVM.ELF over the net using ps2client then you
|
||||
are already set. If you are starting it in any other way, then you
|
||||
will have to "export" the folder where you are storing ScummVM games
|
||||
and data by starting ps2client from inside that folder. Eg. from a
|
||||
terminal:
|
||||
|
||||
> ./ps2client -h [your ps2 ip] listen
|
||||
|
||||
Do this -after- ScummVM is up and running otherwise it will fail to
|
||||
establish a connection.
|
||||
|
||||
|
||||
*** Gamepad ***
|
||||
|
||||
The mapping is:
|
||||
|
||||
Start Button - GMM
|
||||
R1 - 'y'
|
||||
L1 - 'n'
|
||||
R2 - '.'
|
||||
L2 - Numpad 0
|
||||
Triangle - Escape
|
||||
Square - Enter
|
||||
Cross - Left mouse button
|
||||
Circle - Right mouse button
|
||||
|
||||
|
||||
*** Bugs ***
|
||||
|
||||
Though we made our best to make this release as bug free as possible
|
||||
there are still a few bugs left:
|
||||
|
||||
- file handling speed : (not really a bug, but a nuisance) : there
|
||||
is probably space for some more optimization in the current file
|
||||
management. The only case when it really bogs me it's when you
|
||||
try to select a saved game and there is some lag.
|
||||
|
||||
Some game will start faster too when this is optimized.
|
||||
|
||||
- feel free to add your bug, suggestion, secret wish to this list!
|
||||
|
||||
- SCI games have smooth audio and intro, but moving the pointer
|
||||
and in-game animation speed might be a challenge.
|
||||
|
||||
- it has been reported USB media greater than 8 GB might not work
|
||||
|
||||
Now enough reading, rush to your PlayStation2 and start playing!
|
||||
|
||||

Have a lot of fun,
