FINALLY! SD reader for dreamcast

[hackmodford]

Okay... question... do the Sonic games run fullspeed? and does Shenmue run fullspeed and does Crazy Taxi run full speed?

That's probably all I care about (I never really had a dreamcast)

I found my coder's cable and the SD card reader I'm likely to tear parts from (old USB 1.1), now I just need to find my Dreamcast and I'll see about building one of these SD card adapters.

Sonic was considered playable by the person in this video(around 6:40 mark): http://www.youtube.com/watch?v=0gTpylJi9wk" onclick="window.open(this.href);return false;

I guarantee you if someone was to do a triple defragmentation of the files that are being extracted it will boost the framerate problem. I had the same issue with the Knight Raizer when i was creating it. The software is called power defragmenter....

yes I kno the ps2 and the dreamcast is two different systems but its at least worth a try.

More details on this? All I found about defraging a PS2 was the HDD not ISOs (Dreamshell rips and loads to ISO files on the card).

i built the SD reader last night. im gonna say dont bother, barely anything even works and its slow as hell.

Use power defragmenter!....what this software does is it runs a triple pass intensive defrag process on your hardrive/files. This enables the games to be read properly. I used this on open ps2 loader. Before I used it the games were choppy and skipping, afterwards the games played at normal framerate speed all-together.

the transfer rate is less than half that of the GDROM. its going to be slower.

Where can I buy a coders cable?

you really cant anymore unless you find it on ebay.

but, since you have to open the dreamcast anyway to remove 3 SMD capacitors, you may as well integrate the whole reader anyway.

also, please make your sig smaller. its annoyingly large and i think it may be slightly out of date too

[HotDog-Cart]

I'd probably pick up the coders cable, to use it for its original purpose. Screw the SD reader lol. I gots a USB to serial adapter.

Also, sorry about my sig. I'll remove it promptly. Noone ever had issues with it before, but thatsd probably because they were all in awe over my 64DD.

Man I love Hackers.

They do everything better than the companies that built it some times.


Great find. Thanks for the post.


And couldn't you just dump your BIOS and somehow add a flash ROM to it with some code to tell it to boot from the SD card?

Of course, you need a LEET Programmer...

Why is that though.

What TYPE of SD Card are you using?

And if it is programmed terribly and using bad techniques, then it will run slow for sure.

IMAGES PLEASE!!!

Im excited for this Hack...

it doesnt matter. the serial port is slower than any SD card you can put in it

[Haunted360]

What about going through the Modem / Extension port?

I know that is a PCI slot in disguise


Of course, I don't know how but it is another option.

no, its ISA. and only barely. you can pull about 850k out of it. its been done. the best option is going to be hardware emulation of the GDROM drive.

[Haunted360]

Oh, my mistake.

Thats what it said in Wikipedia or some Dreamcast dev site...


Anyway, ISA.

Invented by IBM and stands for Industry Standard Architecture by my memory. Correct me if I am wrong again


So adding the SD card or Hard Drive to the GD-ROM Drive...

This task reminds me of the idea for the PS1/one!


That would be a great hack to achieve, but who has the skill and knowledge on how to actually do it?

[dragonhead]

You do haunted! ^5!!

somehow i doubt that. it beyond the level of marshalls n64 cart. more along the lines of the gamecube DD that people were working on a while back. it was put on hiatus because of the sheer difficulty involved.

[Haunted360]

Yea...


It would take a team of a programmer (which is ELITE), an Electrical Engineer and more helpful people to do it. Even so, there is no point because there not going to make a lot of money from it. They could make some, but not for all that hard work it is not worth it. Royalties yes, because they will be known for their skills but its all about the money for them.
