Rumble Support With Mode B of the EZ Flash ODE

[santiis2010]

Hi, I have a Ez Flash Omega Definitive Edition, you can make this device to act as a DS Rumble Pak by going into the menu and select rumble, then switch the switch to Mode B. But non of my GBC roms detects the rumble, just wanted to know if this is an issue with rom, core, pocket or everdrive firmware?

Thanks.
