Nervous Brickdown locking up at retro stage with an m3 real

has anyone been able to get around this problem? if so how?

freezes/lockups on a flash cart are usually caused by the media card not being fast enough

Suposedly this is a known problem at least for the other m3 series, the m3 perfect has a workaround, so I was wondering if there might be a workaround for this ???
