Dreamshell with hdd ? if it's sd card the better result it means gdemu version is not well optimize.

HDD gives thé better datatransfert, hope the cdda with homebrew will be available one day :-)

@megavolt85 has done a wonderfull job with hydra castle, it's not cdda but a pure delight with dma.

Gdemu or cdr cant be as fast with this engine
it's random multi reading at the same time of 7700 files this is sd card

The gdemu is throttled and can only load one place at time like a cdr the emulated laser can only be in one place at time
But from the sd card it can be in many places reading small files more then make up for it's low transfer rate..

This streams music while loading files which why on cdr or gdemu the sound cuts in and out and any gif files chug now with compression this could be fine problem is it uses lots of ram and we dont have it..

Proof is up there..

it's Got nothing todo with how slow or fast the sd card is it's random reading of multi files is much faster of little files all at the same time..

Gdemu has to load each little file 7700 of them 1 by 1 it would need on the fly compression that would help when you have that compression you have no ram left..
