    • TTMENU.DAT (fake-killer-disabled).


  • Run ttextract.exe with OFFICIAL TTMENU.DAT.

User guide


Change [YSMENU]LITERALS in YSMenu.ini if you use in English or another language (erase a semi-cron).

If you use non-ASCII characters (e.g. Japanese), put next files for an encoding which you use to YSMenu directory (system.fon/system.ank/system.u2l/system.l2u).

Put next files to YSMenu directory if you want/need/use (goomba.gba/PocketNES.gba/hvca.gba/YSMenu1.bmp/YSMenu2.bmp).


Doesn't support Multiple Skins/Themes (It's possible using 3rd party Homebrew).

Start - Use PassMe function or to boot slot2 GBA.
