    PSIO is just name of the proj.
    it based on FPGA that emulate cd-dsp controller and connect directly to cpu IO bus of PS1.

    theoretically this board can used in the ps2 too. but after upgrade it can play ps2 games too. more compatible than by network adaptor/usb-drive or native ETH.

    DC has its own advanteges, cause G1 is IDE-like yet. good soft supporting and good info (about G1/G2)

    no doubt when we make all stuff by our power it takes much time, got a lot of bugs, need soft support, cool mcu for working with ETH stack...in result its very expensive... but its independent device, very small and compact.

    so one of the cheaper way is to use what is made yet and possible to buy everywhere on E-markets...
    and IO board only performs interconnect between consoles...

    so you can choose what you wish

    Yes. PSIO is the name of the project for now.

    Correct. It stands for PlayStation Input Output.

    now i know your just BULL SHITTING
    you CANt just take fucking parts from a PS2 and give it DVD capability's
    you dont know at all how DVD video even works
    why dont you go read the wikipedia on DVD so you'll learn something

    ooh. good reaction.

    i told about what i knew. i've never coded any soft for DVD-video or even DIVX players at all. i have no idea how its works. and dont dont care at all. there are many good coders who knows and can make it.

    maybe you just didnt get what i said. its too hard for you. i forgive you.

    dvd-video is an additional function for console , i'm not interesting in this. that why a cant give answer.

    donate just show - how many people realy ready to buy this item. and workin only on entusiasm really slow.

    but maybe you are good HW or soft developer - show me what you got ? or only another BL-SHT . that's realy annoing

    you do know DVD video requires a HW decoder and software decoder well from a PC perspective thats why a PC DVD drive alone wont let you watch DVD movies

    you need a software decoder for the MPG2 stream witch is very very CPU intensive

    thats why dedicated dvd players in big box stores use hw decrypting and hw mpg2 decoding

    ontop of this the GD-drive is FULLY incapable of reading DVD media
    the lazier is to wide to allow dvd reading thats why it was never included or ever remotely possible to included DVD function in the dreamcast


    also the GD lazier is different from normal CD lasers or else it would be dead simple to replace the dreamcast laser

    ontop of that the GD drive itself cannot read DVD media

    you would need a dedicated HW DVD player to interface with the expansion buss witch isnt worth it

    1 dreamcast game will NEVER be able to be read from and decrypted from the DVD player

    2 buying a 40 dollar DVD player from a big box store solves the issue of playing DVDs no dreamcast needed

    you see how info proves someone isn't a bullshitter and knows what they are talking about

    unlike yourself who has proved NOTHING

    you know this guy who was working on the GD emulator NEVER asked for donations
    and igor NEVER asked for donations to build the ever drive

    he just worked and prototyped all on his own dime
    and when he had something that worked he then built and SOLD the device
    no dreaming no team all one person

    your just trolling people for money thats fucking annoying

    ahahahah you make me laugh , i'm sorry for my english - i'm from russia

    so. and where did i write that if i will conect dvd-rom to DC it can read dvd-video. lol

    i'm not interesting to watch dvd-movie. so i just said - if people wants - they can ask another good coder or someone smart guy like YOU do this. i dont care how, cause i can only give to people capability work with IDE device - such HDD/DVD-ROM/ or any.

    actualy i make it for GAMEs !

    and if we ask donation - we say - IT'S JUST HELP SPEED UP PROGRESS !
    so it just for guys who dont want wait for years. and who want will be in first owners of it.

    its not for people who loves spend money for food , fire water (beer & vodka), collecting butterflies or postcards))))

    and where i trolling money ? i even havnt doation account)))) so what are you talking about???

    if you have any questions (not about DVD-VIDEO) ask me private or in PSIO forum.

    but i supose - i dont want answer such SMART guys like you. who lke work alone for free.

    if you had a proof of concept then people would be willing to hear you
    IE a working prototype until you have that people just wont believe you

    oh and you are gonna need another device to interface with the GD drive also
    because the dreamcast is also incapable from accessing the expansion bus without software

    the games always handled accessing the modem and network card
    the dreamcast did NOTHING to access ether

    let alone the dreamcast needed software that supported the zip drive
    it wasn't capable natively to access the zip drive so the legend goes

    the Dreamcast bios has been well torn apart
    and zip drive drivers have NEVER been found

    Well, if the people doing this project are successful, I want to know. I will be getting this for sure if it can be made to work decently. Use it on a cheap SSD for no moving parts whatsoever. Be perfect for a handheld Dreamcast project. No hard drive or optical drive to fail if I drop it...

    in short - after i make test one i show to all guys.

    about DC : its not news for me what you've written above.

    i just have no much time to do this all for ps1/ps2/dc, but i want talking about my plan and get advice from people. or just exchange of mentions... what wrong you found with this ?

    i know. its better speaking about it after have some proto in hands.

    if your SSD based on standard IDE / SATA IF - you can use it. for another type of cards we can use card reader.

    For the portable one should I build it, I would need a PATA to SATA adapter since most SSDs are SATA format. For my home console, I would use a standard PATA to CF adapter and a bunch of 2GB cards to make this into a slot loader system. Give the N64 it was competing against a run for its money. Have each CF be a dedicated game. I know it would be better to just use a larger storage drive for multiple games but I would want the slot loader idea for the retro aspect of it. It would also be a fail safe for if the card dies, then I only lose the one game versus all of them if they are all on one drive that dies.

    hmm.. maybe you can use SD card (micro or mini size), its smaller then ssd. and can directly connected to FPGA. also you can use 2.5 hdd - and turn it on only for copy to/from SD. then turn off or even release it when you playing the game. all saves you can copy to sd/hdd from dc-mem card from file manager (or DreamShell)

    I would like it to have SATA or USB HDD compatibility. I have lots of games, and to put them on an old unreliable PATA drive, or have them on lots of SD cards would be a real pain.
