Yup.
So for those who don't know, Geckos OS 1.8 uses gpf. files (in contrast to gct.)
It works in a different fashion as gcts but all the same, uses hexidecimal.
gameconfig file format said:
When Gecko boots a game, it looks for a file named gameconfig.txt at the root of your SD card to see if it contains settings for that game. Check the "gameconfig example.txt" file for an example of how the file should look.
-gameconfig.txt format-
Specify a 6 character game id followed followed by a colon, optionally replacing game id characters with ? to match multiple regions/versions, and on the lines after it you specify what settings to change or functions to execute. Repeat for as many games as you want to add. Here's what is currently available:
[value] hooktype - Specify hook type value
0 - No Hooks
1 - VBI
2 - Wii Pad
3 - GC Pad
4 - GXDraw
5 - GXFlush
6 - OSSleepThread
7 - AXNextFrame
Example:
hooktype = 6
This will result in the OSSleepThread hook being used if the hook selected was "Default".
[function] poke(address, value) - Poke address with 32-bit value
Example:
poke(80123458, 01234567)
Writes the 32-bit value 0x01234567 to the address 80123458.
[function] pokeifequal(address1, value1, address2, value2) - If 32-bit value of address1 equals value1, then poke address2 with value2 (also 32-bit)
Example:
pokeifequal(80123458, 01234567, 80234568, 98765432)
If address 80123458 contains 32-bit value 01234567, then write the 32-bit value 98765432 to address 80234568.
[function] hook(<search values>)
Example:
hook(90010014 800305FC 2C000000 41820008)
This is equivalent to selecting the GXFlush hook (sorry, I don't feel like creating a new hook for this example). Currently only hooks with exactly 4 32-bit search values will work with multidol games. The minimum number of 32-bit values allowed is 3 and the maximum is 8.
[value] vidtv - Set to 0 to not apply VIDTV patch
Example:
vidtv = 0
Don't apply the VIDTV patch, which is usually applied by default.
[value] codeliststart - Specify code list start
Example:
codeliststart = 80345678
Loads the code list to address 80345678.
[value] codelistend - Specify code list end
Example:
codelistend = 80358900
Prevents the code list from writing over address 80358900 or any address after it.
[value] videomode
0 - No override
1 - Force NTSC
2 - Force PAL60
3 - Force PAL50
Example:
videomode = 2
This forces the video mode to PAL60.
[value] language
0 - Default
1 - Japanese
2 - English
3 - German
4 - French
5 - Spanish
6 - Italian
7 - Dutch
8 - S. Chinese
9 - T. Chinese
10 - Korean
Example:
language = 1
This forces the game language setting to Japanese.
Now if I read this right, it's possible to boot up PAL games with NTSC codes, and work.
Maybe.
new code types said:
ASM Insert With 16-bit XOR Checksum (ba)
F2XXXXXX YYZZZZNN
ZZZZZZZZ ZZZZZZZZ
ZZZZZZZZ ZZZZZZZZ
ZZZZZZZZ 00000000
YY (signed) 16-bit values after (if positive) or before (if negative) [ba + XXXXXX] will be XOR'ed together and the result will be compared to ZZZZ. If equal, the code will be executed. The rest of the code functions the exact same way as the C2 code type, with NN as the number of lines.
ASM Insert With 16-bit XOR Checksum (po)
F4XXXXXX YYZZZZNN
ZZZZZZZZ ZZZZZZZZ
ZZZZZZZZ ZZZZZZZZ
ZZZZZZZZ 00000000
YY (signed) 16-bit values after (if positive) or before (if negative) [po + XXXXXX] will be XOR'ed together and the result will be compared to ZZZZ. If equal, the code will be executed. The rest of the code functions the exact same way as the D2 code type, with NN as the number of lines.
(If) Search Code Type:
F60000NN XXXXYYYY
ZZZZZZZZ ZZZZZZZZ
ZZZZZZZZ ZZZZZZZZ
Creates an if (so this code requires an endif), then searches for the NN lines of Z values between XXXX0000 and YYYY0000 (or, if XXXX is 8000, between 80003000 and YYYY0000). If the Z values are found, set po to the starting address of the values (SSSSSSSS) and replace the F6 line with F60003NN SSSSSSSS. If the Z values are not found, then set code execution status to false and replace the F6 line with F60001NN XXXXYYYY. To prevent this code from causing game lag, it will only search the first time it is read by the code handler (the result is saved to the code and reused).

gpf file format said:
In order to make a GPF (Gecko Patch File) you will need to use a hex editor. The file should be given named with the game ID and gpf extension and put in a patch folder, that is on the root of your SD card. Here's the patch file format as described by Nuke:
"[1 byte] - Number of patches (hex)
[4 bytes] - Patch Destination (hex)
[4 bytes] - Patch Size (hex)
[Patch X] - Patch data size of Patch Size
example
02 - Number of Patches
91000000 - Destination Address
00000002 - Patch Size (this example 2 bytes)
AABB - The Patch (size of Patch size)
91000004 - next
00000002 - next
CCDD -
The format will be just a hex blob like this
029100000000000002AABB9100000200000002CCDD
and saved to folder 'patch' on the SD card, with the GameID being the filename with .gpf extension, so for red steel ***, the file name would be REDJ41.gpf placed in folder 'patch'."
With a little bit of studying, I can get with this.
Now when downloading, keep in mind that the dol. file is not in the actual directory that you put in the /apps folder (an elf. file is there), you may need an elf./dol. converter to get things going, when I tried to boot it up, there was nothing on the menu, so I'm going to try to convert it to a dol. file.
EDIT: It doesn't work this way, homebrew says it's "not a valid Wii application". Converting it to a dol. file doesn't help, in any case, I'll do more experiments later.
Or allow someone else to find the cause, it may be just me experiencing issues.
EDIT 2, TEH SEQUEL: Instructions from Wiibrew.
wiibrew.org said:
Load boot.elf from Chain Loader. Insert any Wii Game and press reset. Enjoy your region free gaming. As of beta 5, Gecko OS works correctly with the Homebrew Channel.
GeckoOS includes the latest version of the Region Free app, which works with the Homebrew Channel. The latest version has increased compatibility with more games supported and issues running US games on PAL consoles fixed.
Note that while GeckoOS will enable the US Rock Band to load on a non-US console the guitars and drum set will not work (no controller ID lights lit). To load Rock Band try Menu Loader instead.
EDIT 3 TEH TRILOGY:
I found the cause of my issue.
In this, I must iterate that Gamecube memory cards must be removed from the Wii prior to booting Gecko OS 1.8 up.
After booting up, it is certainly still compatible to gct files, so it's okay to get rid of 1.07, not only that, but I noticed that Brawl(+) loaded stages considerably faster than usual.
Must be and IOS thing, seeing how it find the specific IOS needed to play the game. So far, Gecko OS 1.8 is running great, can't wait to see what the people here are going to make with it.
