Dreamcast Hard Drive

[semicolo]

well there's already a working homebrewn 1,5Mbps Usb to serial adapter, with an external clock it probably can be pushed a bit further.
Anyway it means there only lacks for a serial ip stack (slip ?)

Yes, and an actual ethernet RJ45 would help. But we discussed this earlier.

Just while I was reading through
it crossed my mind that the Dreamcast Dev unit found here:-

http://assembler.roarvgm.com/Dreamca...oper_unit.html

it has a Hdd.

Does anyone have one?
Maybe the mainboard of the dev unit could be compare to the dreamcast mainboard and some real answers could be issued.
Like what file system does it use i.e. FAT, FAT32,NTFS ,FATDC/NTDC----LOL.

Also I have an official copy of the Dev unit OS this could be used to install and run apps games as well as develope.

Regards & Good Luck

It has a HDD because it is a dev unit. I believe they installed Windows 98 on it, and cross developed over to the internal DC dev board. It's basically a PC/DC hybrid, and wouldn't help.

That's not the way it works. The Dev unit connects to the PC via SCSI and appears as two devices: the debug adapter and the hard drive. The debug adapter allows you to interface a debugger to the Dreamcast and watch code as any debugger does (you can insert breakpoints, look at memory addresses, etc). The hard drive allows you to transfer over game images made with a special program. Another program allows you to switch between hard drive and GD-Rom mode. In hard drive mode, the dev unit reads from the hard drive, in GD-Rom mode " ".

Thats what I meant, sorry. I was tired and didn't feel like trying for 6 hours.

if im not mistaken, the Dreamcast does have internal memory 16 MB, thats how the dreamcast saved settings for the Web Browser, if there is a way that we could access that and make it larger and accessible then we'll have the Dreamcast Hard drive we always wanted.

You are mistaken. Confusing ram and flash memory.

[Dull Blade]

Your thinking of the DC's RAM (RAndom access memory) that only for playing games. The GD-rom loads data onto that memory and lator processes it in the processor, every time you turn off your DC, the ram is wiped or erased and left clean for the next game you put in. So its more or less just temporary storage, replace your ram with a HDD and your DC wont run or if some how you managed to get it to run, it would be like 1000x slower.

EDIt: looks like quzar got to the anwser B4 i did.

[phisejr]

Lol well if the dreamcast has only temporary memory, then hmm what about making a faster DC instead replacing the RAM ?

or maybe you can use the VMU 128 kb of memory into more then it'll be a HDD or am i mistaken again ?
