======  GBA ExpLoader V0.51  ======

With this program, you can run GBA games in SLOT1 flash cards through SLOT2 expansion pack.

If your SLOT1 flash card supports soft reset, you can use it as "Rumble Pak" or "Memory Expansion Pak".

Supported SLOT2 expansion pack is "3in1 Expansion Pack",  "EZ4 lite-delux" and "EWIN EXPANSION PAK(2in1)".
"NOR mode" and "Rumble Pak" function is enabled only in "3in1 Expansion Pack".

<Introduction>
Please patch the DLDI on GBA_ExpLoader.NDS.
(If your flash card supports auto DLDI patch, you need not to do this.)

*Create "/GBA_SAVE" and "/GBA_SIGN" folder on the root of your SD card.
  (Modify "GBA_ExpLoader.ini", and you can set other folders.)
*Copy GBA files into your SD card.
*Put SAV files into "/GBA_SAVE".
  (If there is no SAV file, it will be created automatically.)
*Put "gbaframe.bmp (24bit or 8bit)" into the root, "/GBA_SIGN" or "/_system_" if you want to use GBA frame.


<GBA ExpLoader.ini>
Modify this file to change settings. To add a comment line, include '#' or '!' character at the beginning of a line.
Make sure you put this file into the root of SD card.
  *SaveDir
    Change the directory where SAV files are stored. (Default is /GBA_SAVE.)
  *SignDir
    Change the directory where SGN files and header.dat are stored. (Default is /GBA_SIGN.)
  *No_MultiSave
    Disable multi save function. Comment out to enable.


===<< IMPORTANT >>===========================================================================
The SRAM save method of this program is different from that of 3in1_ExpPack_Tool.
You cannot use both tools together.
Backup your SRAM first before use this.
==========================================================================


<Usage>
*Run "GBA_ExpLoader.NDS".
*In "3in1 Expansion Pack", <L> or <R> to change mode (PSRAM mode, NOR mode or Expansion mode (if supported)

If you run a GBA in PSRAM/SDRAM mode, SAV will be saved next time.
You can select where to save or not to save.

  (PSRAM/SDRAM mode)
  *<A>: Write a GBA file into PSRAM with SRAM patch.
    Load SRAM data from SAV file.
    Then run GBA from PSRAM.
  *<B>: Backup SRAM data to SAV file.

  *<Y>: Restore "SRAM.BIN" to SRAM.
  *<X>: Backup all SRAM data to "SRAM.BIN".

  *<R>: Patch PSRAM for DS Browser and soft reset. (Disabled when your pack is "3in1 Expansion Pack")

    With "3in1 Expansion Pack", you can run a GBA up to 16MByte (16000KB) in PSRAM mode.

    And <SELECT> to return to your flashcard's menu if soft reset is supported.
    You can run GBA from RAM until turning off DS or pulling out your expansion pack.

    When you want to exchange SAV file, <B> to backup SAV data (or run another GBA) first and then exchange the file.
    SAV file will be written into SRAM every time you run the GBA, even if you run the same file again and again.

    If your expansion pack has only 128KB SRAM, you cannot run GBA with FLASH 1Mb save.


  (NOR mode) Enabled only with "3in1 Expansion Pack"

  *<A>: Backup SRAM data to SAV file.
    Write GBA file to NOR with SRAM patch.
    Then load SRAM data from SAV file.
  *<B>: Backup SRAM data to SAV file.
  *<Y>: Load SRAM data from SAV file.
  *<X>: Run GBA (Slot2) stored in NOR.

    You can also run NOR in DS menu like a normal GBA cartridge.


  (Expansion mode) Enabled only with "3in1 Expansion Pack"
   Change Rumble level (low/medhium/high) and patch PSRAM for DS Browser and then soft reset.

<Composition of SRAM of 3in1 Expansion Pack and EZ4>
  SRAM capacity is 512KB (4Mbit) and you can use it by 8KB(64Kbits) paging.
  Save area for NOR is stored from offset 64KB like this:
64KB      UNUSED
128KB      SAVE area for NOR
8KB      SAVE management area
128KB      SAVE are for PSRAM
Rest of space   UNUSED

<Composition of SRAM of EWIN EXPANSION PAK>
  SRAM capacity is 256KB (1Mbit) and you can use it by 64KB(256Kbits) paging like this:
128KB      SAVE for SDRAM
64KB      SAVE management area
64KB      UNUSED
  or if your pack has 128KB SRAM, composition is like this:
64KB      SDRAM用SAVE
64KB      SAVE management area


<About soft reset>
SLOT1 flash card which supports soft reset is:
  1. Supported
   R4/M3Simply
   DSLink
  2. Use system file
   SCDS(ONE)
   N-Card      Please copy udisk.nds to the root of SD card.
   Acekard R.P.G   Please copy akmenu4.nds to the root of SD card.
   X9SD
   DSTT(TTDS)
  3. Use firmware file
   If your flash card doesn't be listed above, backup your flash card and name it SoftReset.****, and copy it to the root of SD card.
*SC DS ONE:   SCF_DSGB00.nds -> SoftReset.SCDS
*G6 DS Real:   PASSCARD3_AMFE00.nds -> SoftReset.g6ds
*G6 DS Real:   PASSCARD3_AMFE00.nds -> SoftReset.M3DS
    You cannot use this method on R4, Evo, AK and AK+.

    *EZ5 supports soft reset, but Rumble or Memory Expansion function will be disabled in EZ5 Keanel menu.


<Repairing of header>
  GBA ExpLoader will repair corrupted header of GBA. (BIN file will not be repaired.)
  Due to some reasons, please setup before use this function.
  First, cut out head 256Byte from commercial GBA ROM.
  Second, rename it header.dat and copy to "/GBA_SIGN" folder.
  If you cannot understand what I mean, use small commercial GBA ROM as header.dat.


<Notice>
*If save type is not SRAM, GBA ExpLoader Will patch SRAM automatically.
  Supported save types:
   EEPROM_V111, EEPROM_V120, EEPROM_V121, EEPROM_V122, EEPROM_V124, EEPROM_V125, EEPROM_V126
   FLASH_V120, FLASH_V121, FLASH_V123, FLASH_V124, FLASH_V125, FLASH_V126
   FLASH512_V130, FLASH512_V131, FLASH512_V133
   FLASH1M_V102, FLASH1M_V103
   Special save type of Famicom Mini(Classic NES)EEPROM_V122, EEPROM_V124 and undefined type

*The size of SAV file will be adjusted to the real SAVE size.
  But GBA ExpLoader cannot detect EEPROM 512B or 8KB, so all EEPROM size will be 8KB.
*If GBA ExpLoader cannot detect save type, it will be set to SRAM 64K.
*It's OK even if SAVE data has dummy area at the tail of the file. E.g. real file size is 64K but file size is 128K.
*SAV file will be saved to "/GBA_SAVE". File name will be the same of the ROM file name.
*When you run a ROM first time, analyzed data(SGN file) will be saved to  "/GBA_SIGN".
*If file extension is BIN, GBA ExpLoader won't patch. And SAV file size will be set to 64KB.
*In file select window, top "SAV" will be saved as ".SAV" and <1> to <5> will be saved ".SV1" to ".SV5"
*You'd better create "/GBA_SAVE" and "/GBA_SIGN" yourself.
  (Some Slot1 flash cards cannot create these folders correctly. N-Card series will take a long time to do this.)
