Eso si, de momento nada de un menú para elegir isos ni nada similar, un botón para ir cambiando de juego y listo
Compatibility:
GDEMU is compatbile with VA1 model Dreamcasts from all regions
IMPORTANT: VA2 model is not compatible. Mating GDEMU with VA0 model mainboard is possible but will cause permanent damage to the device. See installation instructions.
Supported memory cards:
SD: 512MB, 1GB, 2GB
SDHC: 4GB, 8GB, 16GB, 32GB
Other cards might work (SD smaller than 512MB and SDHC bigger than 32GB) but were not tested and are generally not recommended.
IMPORTANT: 4GB SD cards are NOT supported. Neither are SDXC cards of any kind.
SD cards come in various speed grades called classes. Usually class 4 cards offer good enough performance and there is little need for anything faster. Even class 2 might work well, you’ll have to try and see.
In fact speed class only tells you how fast the card is during streaming, not what the random access latency is. It’s possible for a good class 4 card to outperform a medicore class 10.
IMPORTANT: There are many brands available, and worse yet, a lot of counterfeits. Some cards appear to be more stable than others so if you get any weird issues like GDEMU failing to detect the card sometimes, or random hangs after a few hours of play, try a different brand/size card.
In general it’s better to stick to 2-8GB cards from well known manufacturers, and if you’re using a size adapter make sure it’s a quality one.
Supported filesystems:
FAT (also known as FAT16)
FAT32
IMPORTANT: exFAT is not supported.
See card preparation guidelines for optimal choice of filesystem.
Supported image types:
GDI for GD-ROMs
CDI for MIL-CDs and bootable homebrew apps
ISO (as data carriers for homebrew)
IMPORTANT: Recently some new dumping groups have been releasing GDIs dumped with PC CD-ROM drive using so-called “swap method”. Technically there is nothing wrong with it except for slightly different “offset” on audio tracks compared to what Dreamcast drive would produce, nothing you’d even notice. But they’ve changed the way track starting address is calculated and as a result all games that have digital audio, or data split beyond track #3, will not work properly. This is not a GDEMU issuse and there is no fix planned for this – avoid such dumps.
Card preparation guidelines:
Cards up to 2GB should be formatted with FAT16
Cards bigger than 2GB should be formatted with FAT32
Use the biggest cluster size available (32kB in most cases, 64kB clusters are also supported)
DOS partition table is supported but only first partiton will be used
For best results use software called SD Formatter
SD Formatter can be obtained free of charge from Panasonic, and recently also SD Association. It will adjust the format settings automatically to extract best performance out of your card.
Image layout:
Every image must be put in a separate folder
Folder names must consist of 2 digits, 01 to 40
All file names must be in DOS 8.3 format
The main image file must be called “disc” with appropriate extension
IMPORTANT: Long filenames are not supported, neither are names containing non-ASCII characters. You can, however, put a file named with the game title in each folder for better organization, even if it’s a long name – it will be ignored by GDEMU.
An example of correct filenames for GDI image:
track01.bin
track03.bin
disc.gdi
track02.raw
Hi, guys and gals,
I finally got the DCIO board programmed yesterday.
I managed to Flash the ARM chip correctly using the "bossac" program that is used by the Arduino software for the Arduino Due etc.
But, I couldn't get the SPI Flash chip (EPCS) for the FPGA to program correctly. Quartus just kept saying "Device signature not recognized".
Turned out to be a silly mistake on my part (usually is. lol) - I forgot to solder one of the 10K pull-up resistors on one the FPGA pins.
Anyway, it should be programmed now, I just need to solder the connector for the DC tonight then try some games.
Apologies again that it's taken me so long to get this far.
I'm still getting over an evil Man Flu that I've had for a month now, so I've been unable to do any soldering or anything.
cybdyn has been busy testing games, and adding to the DCIO firmware though, so it's still in progress.
He thought of the clever idea of allowing the standard ATA commands to be used for giving full access to the SD card.
All the CD / GD accesses are done via ATAPI / "SPI" commands of course, so it makes sense to use ATA for SD access.
This will keep it more compatible to the IDE / ATA code in KOS / Dreamshell, and there has also been excellent progress on that as well recently...
http://www.dc-swat.ru/forum/thread-2111 ... l#pid26695
So looks like I'll need to get a big batch of new G1 IDE adapters made (with bug fixes / improvements).
That includes the fact that the old adapters didn't quite fit when the DC mobo was in the case.
The IDE adapters with Dreamshell will be an alternative to the DCIO, but the DCIO will certainly be the most compatible and we hope to add CDDA support soon.
(Playback of CDDA tracks may even be possible under Dreamshell, but it will be a huge programming challenge tbh.)
So, just grabbing some food, then it's time to solder the connector to the DCIO.
cybdyn has sent me new e-mail replies and code as well, so I need to catch up with that.
Regards,
OzOnE.Oh well. A bit of "healthy competition" I suppose. lol
Again, just a tad strange that he wants to release his GDEMU now after all this time, and after he said many months ago that he doesn't condone "piracy" with the device and wouldn't be releasing it publicly. hehe
Good point about the game selection though - I forgot that almost every game will return to the DC menu if the tray is opened.
The DCIO will use a proper on-screen menu for game selection of course, so there won't be any buttons hanging out of your DC.
You may have to power the DC off-and-on to get back to the game menu though. We haven't worked that part out yet.
€100 price tag for the GDEMU isn't too bad I guess, but we may be able to beat that slightly as well.
OzOnE.

Bueno es que parece que el precio es bastante competitivo, si vemos que la "competencía" no cree poder mejorar mucho ese precio y incluso podría ser superior, esperemos que salga algún "chinaco" que sea más competitivo, pero la pasta es la pasta...
Yo como que con los gdroms/backups que tengo voy tirando, pero hay que reconocer que es un cacharro que puede dar mucha vidilla a la consola, lastima que de momento no pueda convivir con el lector.
