Applies SRAM, IPS, and EZ4 header patches. Applies special header patch for compatibility with EZ Flash 4. Did I mention it's compatible with the EZ4? That means it's compatible with the EZ4. Which means the official EZ4 client is no longer necessary. No longer necessary. Smell the freedom.
There's no official website for this app. The only place you should be getting this file from is from my thread at gbatemp.
ezgba is released under an unrestrictive license. See COPYING.txt for details.
Windows, Mac OS X, and Linux are all supported. Everything is written in C++. CMake, Boost, and wxWidgets (if building GUI) are required to compile. Supports GCC v5+ as far as compilers go.
SRAM patches are 1:1 with gbata, but with some exceptions:
- gbata will ensure the ROM padding is either all
0x00or all0xff. ezgba can do this too, but doesn't determine if0x00or0xffshould be used as the fill value the same way gbata does. This should be of little practical consequence. - There are about a dozen or so ROMs that require specialized SRAM patches instead of generic patches. gbata will handle them, I won't. You can search for some IPS patches on the internet as a solution.
There are about a dozen games that use FLASH512_V133, which isn't supported
by my patcher. gbata doesn't support these either, and I haven't found a GBA ROM
patcher that does. But as all 11 ROMs are of the 2-in-1 and 3-in-1 variety, I'm
not too concerned about V133.
The EZ Flash 4 client will apply a special header patch to the ROM's reserved
area 1, which stores information regarding the ROM size (0xb8:0xb9) and save
size (0xba:0xbc). 0xb5:0xb7 is zeroed out, for an unknown reason.
Without this header patch, ROMs on the EZ Flash 4 are still playable, but won't save properly. Other flash carts may need their own special patches.
The EZ4 special header patch is supported, and is applied by default.
Both the RLE and truncate extensions are supported. Some ROMs require specialized IPS patches for save patching instead of generic SRAM patches; in this case, you'll need to disable the default SRAM patching, and use the IPS patch only. If you plan to use it on the EZ4, the EZ4 header patch still needs to be applied.
These are ROMs that either have multiple save strings, that gbata has
specialized patches for, or uses FLASH512_V133. To patch any of these ROMs,
you need to manually select and apply the appropriate IPS patch(es).
