Gecko OS: 256-line limit => Code Dump Issues?

[351:Insomnia]

Stated from the topic, I'm having Black Screen w/ Code Dump Issues from the later Gecko OS. I am fully aware that it may be the codes that's incorporated into a new .GCT file  :-\ But I never did get message saying: "Too many codes lines", because usually it'd say that and just boot up the original disc? So, my questions are could it actually be the 256-line limit? If so, is there a way to bypass this rule?

Make a TXT file at the root of your SD card called "gameconfig.txt" (no quotes, obviously).

Add this to it.

Code Select Expand

RSB?01:
codeliststart = 80570000
codelistend = 80580000
poke(800042B8, 60000000)
pokeifequal(803E9930, 4BFECA1D, 803E9930, 60000000)
pokeifequal(803E99A8, 4BFECA1D, 803E99A8, 60000000)
pokeifequal(803E9D5C, 4BFECA1D, 803E9D5C, 60000000)
In the question mark, put your game region. Seeing as you're from California, put in "E" for the question mark.
E=NTSC-US

Attempted, but no altered results.

Apparently, the way I'm creating the GCT in CodeManager is the problem. Used GeckoCodes.org Online GCT Creator, and it went through. Appreciate the needed contents Segtendo.
