Zip drives are crap. Better off using the thumb drives.

Actually, I am really thinking about this. After I finish up some coding for a project I entered and get out of that project, I am going to actively pursue this. It will come out just in time for the PS9 release. I know there is skepticism and some people think I am just an idiot by even trying to defend my idea, but Im gonna at least try so that way I dont try something stupid again. I may even learn something.

But I guess it is kinda pointless. I mean, how many dc fanatics are going to buy a zip or hard drive just for a homebrew game :?: And I wont even succeed. Well, good luck pyrosurfer!

Forgot to ask, Kamjin, how hard would it be implement DMA? I realize you would have to make a new driver, but would the hardware part of it be hard to design? People were saying it is the lack of DMA that made it so slow.

I'm also tied down at the moment, I won't be able to start till months later.

DMA and interrupts, too.

DC's DMAC wasn't designed for it, so it would have to be implemented via some sort of controller, which would make it to complex for hobbiests..

Even a software driver is fast enough.. up to the mid 90's dma for HD's on IBM type PC's was practically non existant, and in general the use of the hd would be homebrew/bsd/linux. which still proves more than fast enough, even if you reach speed of 1mb/sec with all the other program overhead, consider the largest existing HB game would take 4-6 seconds to load into memory. Even to store your mp3's and Oggs.. it's more than fast enough, to stream them off the HD. In reality you should be able to get 1-2MB/s with game/app overhead included.

I still think a HD is a fun idea, even with a simple filesystem, and a cute gui, it can be used to load all the Hombrew that's single file w/o modification, emu's can be compiled with hd drivers to look for rom's on the HD etc.. For homebrew dev it's also a nicety for those who don't have a bba, simply use the HD to store all the data files, and just use serial up the main executable.

Yeah, IDE HDs in PCs to this day still eat up a lot of cycles when they're in use. Enough that you don't want to stream during gameplay, for instance. But that kind of eliminates use for swap space, at least in stuff like emulators.

IF some one really took the time and money thats really needed you could proably end up with a HDadvance type product like for the PS2 and that might be one of the uses for it. Back up your DC games on the HDD and run the games off of that. Would be cool and have faster load times and save the Gdroms life.

not really. while in a slight sense it does involve warez, morally, if you own the original game and know how to make a backup of it, its perfeclty fine, although it may not be legal in this corrupt country of ours :roll:

but the HD idea is still way down the road. we may see it, but is far down there. here are some problems:

-no widespread production of the hardware. only available to those who can build one.

-homebrew software to take advantage of it

-if using it as a replacement for the gd-rom, only one game could be loaded at a time (correct me if im wrong here) if using commercial games. homebrew sbi's would work fine.


dont get me wrong, id love to see a HD adapter made and supported even by just a small fraction of homebrew games. ive got a small 3GB hard drive sitting here unused and even it would make an awesome storage device for the DC. but i just dont see it becoming widespread. this is more of one of those things that is not feasible in a homebrew sense, but rather something that should have (or could have) been built by Sega themselves or a licensed professional hardware developer (such as Iomega or Madcatz, etc..)

This would also improve the use of running linux on the DC.

Hmmm i got thinking sense Linux detects all hardware couldnt you Install the live cd on the DC or hardrive and then start poping in GDroms and backing them up on there. BRILLIANT :D But then you would have to find a way to run the games from the Hardrive. Could also help some of the offline games go back online by modifying the Iso and putting in new IP address so it connects to the Euro servers for PSO (phantasy star online) :idea:

In theory you could, but running the games from the harddrive would be hard, but bluepunk, thats warez, again.

Dan Potter got homebrew to run off his. It would be too slow for commercial games.

no.

IF you could make the HDD a VMU it would only display 200 blocks anyway as the size of a vmu is set by the DC not the vmu it self

Homebrew could store however many saves on the hdd as you wanted. Commercial games would not work at all with it though, unless you hacked the game.
