-------------------------------------------------------------------------

This is a tool that lets you load isos(backuped from your original umd's) compressed in dax format (a custom format, compressor and decompressor are included).


Requeriments:

- 1.50 firmware

- UMDEMULATOR 0.8c (optional, daxziso already incorporates in his core the UMDEMULATOR core)

- Optional: RUNUMD (for some 2.XX games) A modified version of MPHGL is included from this release.


Instructions:

- Copy the folders PSP and DAXZISO in the root of your mem stick.

- Compress your iso with the DAX Creator tool that is in this package.

- Copy your compressed iso (.dax) to ms0:/ISO or alternatively to ms0:/UMD

- Execute DAX ZISO Loader. Select your iso (normal or compressed) or "Run inserted UMD", press X to start inmediatly the iso/umd with the previously saved config, or press square to go to the configuration screen.

Configuration screen: you'll have to choose the emulation mode and other parameters.

* Explanation and compatibility of differents emulation modes:

- Off: the iso won't be emulated and the program will exit to the system menu. This method only has sense if you want to emulate the flash0 & flash1.

- System menu. It returns to the system menu, letting you to load the game through the system menu or another loader like mphgameloader or FastLoader("Start inserted UMD").
This is one of the most compatible modes, it is more compatible than the UMDEMULATOR system menu.

- Direct load. It will directly load your iso. At the moment, it seems that this mode is less compatible than the "System menu" and "Direct LoadExec" ones. Be always sure that you try the different modes to see which one is the best for your games.

- Copy load. It will copy the game boot.bin file to ms0:/DAXZISO/DBOOT.BIN and it will load-exec it.

- MPHGL Direct. This mode needs the file "ms0:/DAXZISO/mphloader.prx" of the MPHGameLoader application, which is already included.

Note that this is a modified version of mphloader.prx which will search the flash0 and flash1 in ms0:/DAXZISO/flash0 and ms0:/DAXZISO/flash1. If you want still use the older folders at ms0:/MPHGameLoader/flash0 and ms0:/MPHGameLoader/flash1, simply replace the mphloader.prx of DAXZISO with the original one from ms0:/MPHGameLoader/mphloader.prx

It seems to be the less compatible mode of all.
It's more compatible to use the system menu one and execute mphgameloader, or the modes "MPHGL System", "MPHGL VSHExec" and "MPHGL LoadExec".

- UMDEmulator:

This mode requires the file ms0:/DAXZISO/UMDEMU.PBP, which is already included.

This mode will load the original umdemulator letting it to load isos in dax format.
The compatibility of different load modes inside UMDEMULATOR should be more or less the same that those from DAXZISO, although it may have some differences.

- MPHGL System. This mode returns to the system menu: in that moment you can run your emulated umd from the system menu. Instead of executing the disc, the firmware will execute the file "ms0:/DAXZISO/MPHGL.PBP" which will load your 2.XX game.

The required file "ms0:/DAXZISO/MPHGL.PBP" is already included.

The compatibility of this mode is greater than "MPHGL Direct" and exactly the same than exiting to the system menu and then running mphgl.

- MPHGL VSHExec. With this mode your psp will reboot and after that it will auomatically run MPHGameLoader ("ms0:/DAXZISO/MPHGL.PBP").

The compatibility of this mode is greater than "MPHGL Direct" and exactly the same than exiting to the system menu and then running mphgl.

- Direct LoadExec. This mode looks like "Direct Load", but instead of using the sceKernelLoad/StartModule functions, it uses sceKernelLoadExec; because of that, the system will have more free memory, and this makes it more compatible than "Direct Load" and almost as compatible as "System Menu". The only problem is that it always will run the BOOT.BIN
file (even if that option is in off), because sceKernelLoadExec fails with EBOOT.BIN.
If you have one of those game that in umdemulator only worked with copy load, try this one, it loads faster and there are chances that it work.

- MPHGL LoadExec. This mode is as compatible as "MPHGL System" and
"MPHGL VSH Exec", but it loads faster. However it has a problem: it doesn't work depending on the wlan switch position. In my psp, it works with the wlan position in on, but it may be different on your psp, or even different from a game to another.

This is NOT a DAXZISO bug. I've tried to execute the mphgl eboot.pbp with other homebrews programs that also use the sceKernelLoadExec function, and without iso emulation (original umd), and the results where the same: depending on the wlan switch position it worked or not.
I cannot solve a bug that it's not mine.

- RUNUMD LoadExec. This mode will run RUNUMD, and it will let you load isos with it.
Because of a special patch that is applied in this mode to the UMDEMULATOR core to fix a compatibility issue with RUNUMD, the flash0 and flash1 emulation are broken in this mode.

This mode requires the runumd pbp (folder without %) to be in ms0:/DAXZISO/RUNUMD.PBP
This file is NOT included, you'll have to provide it.

- RUNUMD System. This mode returns to the system menu. After that, you can run RUNUMD with the disc icon of the firmware. You can also start runumd from the your memory stick if you want.

This mode also requires the file ms0:/DAXZISO/RUNUMD.PBP and it also has the flash emulation broken.

Note: if you use one of the other "System Menu" modes and you start runumd, it will gives you the famous error of "patcher failed", because daxziso doesn't apply the special patch to those modes in order to keep compatibility with flash emulation.

- RUNUMD Direct. This mode is like "RUNUMD LoadExec", but it doesn't reboot the firmware, so it loads faster and it doesn't delete a background program from memory. The compatibility should be less than "RUNUMD LoadExec", although it seems still to be very good.


Remarks:
* After having exited a game that you have run with a MPHGL mode, if you want to run again the game, you can simply click the firmware UMD icon. (from this version, this applies to all mphgl modes).

* The same for RUNUMD modes.

- Option "Allocate tables in RAM". If your game worked well in version 0.3, leave this parameter to "on", because decompression will be faster than in "off". If you game didn't work in version
0.3, set it to off: that will decrease memory use and increase compatibility.

- The other parameters are handled by the UMDEMULATOR core and their meanings are the same than in UMDEMULATOR.

- To quit ISO emulation, execute the loader and press triangle.


The loader will remember the configuration of each iso (in umd it will only have a configuration for all umd's at the moment).
The configuration files are saved in the ms0:/DAXZISO/CONFIG directory, with the name "[name of iso including extension/s].dat" (example: megaman.iso.dax. -> megaman.iso.dax.dat)

If you want to share the settings of your games with your friends, you can zip the config folder and send it to them, but remember that all of you have to use the same file names.

You can also have a custom background for each iso.
Backgrounds can be stored now in a lot of manners to make things easier, in either the folder ms0:/ISOMISC or ms0:/DAXZISO/BACKPIC

Better an example than an explanation. If you have an iso called "Tales_Eternia.iso.dax", the program will search a background in the following order:

ms0:/ISOMISC/backpic_Tales_Eternia.iso.dax.bmp
ms0:/ISOMISC/backpic_Tales_Eternia.iso.bmp
ms0:/ISOMISC/backpic_Tales_Eternia.bmp
ms0:/ISOMISC/Tales_Eternia.iso.dax.bmp
ms0:/ISOMISC/Tales_Eternia.iso.bmp
ms0:/ISOMISC/Tales_Eternia.bmp
ms0:/DAXZISO/BACKPIC/backpic_Tales_Eternia.iso.dax.bmp
ms0:/DAXZISO/BACKPIC/backpic_Tales_Eternia.iso.bmp
ms0:/DAXZISO/BACKPIC/backpic_Tales_Eternia.bmp
ms0:/DAXZISO/BACKPIC/Tales_Eternia.iso.dax.bmp
ms0:/DAXZISO/BACKPIC/Tales_Eternia.iso.bmp
ms0:/DAXZISO/BACKPIC/Tales_Eternia.bmp


The background must be 24 bits color bmp's, and with a resolution of 480x272 pixels.
Otherwise, the program will paint a white background to let you know that the file was in an incorrect format.


FAQ:

- Q: Will support DAX ZISO Loader more common formats of compressed files like .zip, .rar, .gz?
- A: NO. I already did testings with .zip and .gz files, and the EXIT JAP iso was still loading
after more than 10 minutes. The problem with those files is that the seeking is really slow.
That was the main reason behind creating an own format. The DAX format is very similar to
the .Z/.Z.table concept, except that it's only one file and other few changes.

-Q: Can load DAXZISO games that UMDEMULATOR/MPHGameLoader cannot?
-A: No. The iso emulation is still done by the UMDEMULATOR core, although the reading functions
are redirected to the DAXZISO one. However, the system menu has been reported to be more
compatible in DAXZISO (from version 0.4) than in UMDEMULATOR. (this is probably due to a
patch that DAXZISO does)

-Q: Can DAXZISO load normal (non-compressed) isos?
-A: Yeah, no problem.



Changelog:

- 0.55. April, 21

* GUI changed, made text more visible and usage faster. Now X button start directly an ISO/UMD with the saved configuration and square button jumps to the configuration screen.
* DAX ZISO now uses an only folder, ms0:/DAXZISO, instead of UMDEMULATOR, and also subprograms must be stored in that folder. Please, read the readme to migrate from previous versions. Also, isos are now searched in both, ms0:/ISO and ms0:/UMD folders.
* ISOs are sortered alphabetically.
* Compatibility with Hard Disks have been improved.
* Added the mode RUNUMD Direct, which loads faster than RUNUMD LoadExec and it doesn't restart the kernel (so, an app can be running in the background)

TODO:

- Improve the speed of the decompression/reading when "Allocate tables in RAM" = off

- Correct the annoying bug of sleep mode. It has a HIGH priority now in this list.

- remove the needing of having an umd.

- Extend the DAX compression format with more options.
