You can get more speed if try adapters on chip cp2102.
Some adapters can works up to 500000 baudrate with DC. It's ~10x faster than 57600. But not all adapters can do it, for me works only on red PCB.

Where can I find the cp2102 chip?
Do you use BBA to test Dreamshell games using dcload?

This is it?:

FTDI намного лучше cp2102, они без проблем работают на скорости до двух мегабит

У меня он почему-то вообще только на 57600 работает...

ISO Loader supports dcload (serial and ip) as device. But I haven't tested for a long time.
Unfortunately BBA is much slower than IDE. And there is little point in running games over the network.

In Dreamshell you only have dcload_ip. Where is this dcload-serial?

why is that? HIT-400 supports 100 Mbit/s, more then enough to play any game and even HIT-300 supports 10 Mbit/s that is equal to x16 DVD-ROM speed. I play ps2 via smb all the time
isn't IDE transfer speed is somewhere around 100 Mbit/s as well? or the problem in the speed of BBA bus?

Boot DS core from your dcload and share directory with games:
Go to ISO Loader, browse directory /pc for games and try launch.

I did not say that this speed is not enough for games, because many work fine with SD
In fact, BBA in dcload give me ~20-30 Mbit/s and IDE works on 80+ Mbit/s.
Also for games need rewrite BBA driver in dcload, need make it async, use DMA and etc. It maybe speedup, but... It takes a lot of time for this to work properly, but what's the point if very few people have BBA.

BTW.
Marcus Comstedt (very famous on dc scene), tried to make his own loader with BBA.
But judging by the code, it will hardly work faster, and the compatibility with games will be DS RC1 level.

Код:

dc-tool-ser -c ./games -t /dev/ttyUSB0 -b 57600 -x DEBUG_DS_CORE.BIN

Go to ISO Loader, browse directory /pc for games and try launch.

How to partition the sd card? I made the partition show as sd1 but it doesn't open in dreamshell.
