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

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

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

A patch is released for GBA Exploader so it'll work on M3DS Real and iTouchDS.

Installation

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 are no SAV files, they will be created automatically).

Put gbaframe.bmp (24bit or 8bit) into the root, /GBA_SIGN/ or /_system_/ if you want to use GBA frame.

User guide

You can choose between 3 modes if you use the 3in1 Expansion Pack:

• PSRAM mode.
• NOR mode.
• Expansion mode (if supported).

PSRAM/SDRAM mode

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

• Write a GBA file into PSRAM with SRAM patch.
  • Load SRAM data from SAV file.
  • Then run GBA from PSRAM.
• Backup SRAM data to SAV file.
• Restore SRAM.BIN to SRAM.
• Backup all SRAM data to SRAM.BIN.
• 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.
• 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:

• 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.

• Backup SRAM data to SAV file.
  • Write GBA file to NOR with SRAM patch.
  • Then load SRAM data from SAV file.
• You can also run NOR in DS menu like a normal GBA cartridge.
  • Run GBA (Slot2) stored in NOR.

Expansion mode

Enabled only with 3in1 Expansion Pack.

• Change Rumble level (low/medium/high).
• Patch PSRAM for DS Browser and then soft reset.

Repairing of header

GBA ExpLoader will repair corrupted header of GBA.

Savedata

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.

Additional:

• 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 set to 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 the 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).

Controls
