    have no idea about any CG programs, my current FW for psio is compatible for both types : SD and SDHC.

    i can explain more details how i handle this difference between types- but dont see any reasons say it.

    Wow ,,I must say this is neat , a man I thought to be a farce has some how obtained results. Even with this video I am still skeptical, Also why is there a screeching noise after he hits the switch on the power outlet?

    Usb support would be better than sata because the converters for sata are cheap and small, while sata to usb might not even exist. Also nowadays, there is almost no difference in price for a sata or usb hdd. Additionally you will have to worry about static discharge if the drive is mounted externally(sux for warenties).

    If it was a n64 and previous flashcart ,I would say sd only support makes sense. Even with sdxc it would be impossible to have my whole psx collection at hand. As a buyer of almost every ODE and flashcart, I can tell you, not having usb support would suck, and in the long run would be more expensive and fumbly(having to carry around multiple sd cards). I would pay extra for that support also.

    "Also why is there a screeching noise after he hits the switch on the power outlet?" - what noise?

    i wanna use USB(host) too - cause no need define on low level access to all SD types , like sdxc or what ever, just buy usb card reader with card what you like

    IT may be the fact I'm using a 7.1 surround sound audio setup. I can hear everything. Seriously watch the video on the site right after he taps the switches on the outlet the screeching starts. The sound starts at 1:08.

    1- first i plug usb of psio to pc, ps1 is off!
    2- launch app for connect/open tusb device
    3- push power on ps1, it starts up bios code
    4- before any command to read data from cdrom(psio) i send base addr of image to psio... game start loading - we see ps logo

    so maybe that's why you see pause between points

    i can just setup default base addr of image in firmware of mcy - so no need pc at all.

    also - bad noice is caused of crt monitor- read description under video

    No, a theory is unproven "A supposition or a system of ideas intended to explain something". Conspiracy theorists take an event and build a series of ideas around it, they generally need to pick and choose what facts they believe and which facts they discard to make their theory work. At that point they believe that their theory disproves all the facts that contradict their theory, usually by saying that those facts are manufactured as part of the conspiracy.

    This is different to someone who uncovers a conspiracy.

    If you have enough people coming up with conspiracy theories then some of them are actually going to be correct. But that is like someone lying but it turns out that they were wrong as well, so what they are saying so true but they were trying to deceive you. Most actual conspiracies aren't discovered through dumb luck like that, it's people who discover tangible evidence of conspiracy.

    For example, these people are conspiracy theorists. http://en.wikipedia.org/wiki/Architects_&_Engineers_for_9/11_Truth They believe that the WTC couldn't have collapsed the way it did, therefore decided it must have been a controlled explosion. They may be right or wrong, but they have no proof either way. It's very difficult to model such an event and even though people might have experience of how buildings normally collapse it doesn't mean they didn't collapse of their own accord. Nothing happens until it does for the first time. However if they found explosives in the rubble or found some evidence of plotting, then they would not be conspiracy theorists.

    Just because you're paranoid, doesn't mean they aren't out to get you.

    You have to put your own code after powering up your ps1, that's how PIO works, but I don't see anything like this on your video (or through your explaination).
    Sending "base addr of img to psio" isn't enough at all. You have to patch the loaded iso, either on the fly, or hard patching the binary, but you're missing something in your explaination.

    And this method would work if the game was using psyQ library, but what apout games which uses low level communication with cd-rom ? You have to create a device connected to the cd controller connector.

    what code? psio is hardware emulator of cd-rom controller.

    do y know how read schematics of ps1? look attentevely to pio and cd-rom controller (cxd1815 on scph-5502 or cxd2938 on newer versions)

    It's just capacitors. When they get old they whine and make noise. My monitor does it when it's turned off on the bezel, but not at the plug.

    it's not last video... anyway key moment will be when we send/sell psio to testers. and they explain more and tell what it can.
    i would like discuss about technical questions, but not about noise, conspiracy, doubts...

    Don't you need to answer the question about the use of Gemini's resources? You can't exactly Sell the PSIO if he doesn't let you use it.

    Sure they can, if the code was GPL. But they need to upload their source and also retain credit where appropriate.

    i wrote - i didnt use Gemini's code. and we dont sell software - it's the gift for psio))) so in any case i dont think about such questions .
    else, i see you can buy game discs for PS1 for example on Ebay, and i remember there are signs like "NOT FOR SALE" (or resale) but everybody dont care.

    and dont forget his code is not finished, it only shows text strings with some kind of background, i think he used some kind examples too, i mean most of home brew programmers learnt/used examples and source files from sony or dont know from where - but not create from zero, or something extraordinary))) so dont need make from G - such great hero that we cant do w/o him )))

    Your understanding of those stickers is flawed.

    The idea is that game company A bundles a game with their console. By slapping NOT FOR RESALE on it the idea is that the retailer won't try to separate the game from the bundle to resell it. Other instances are for demo carts/discs used in kiosks (which are supposed to be returned to the owner and NOT resold). It is not nor has it ever been intended to prevent individuals from reselling games.

    Nope, my sources don't come from samples. Samples don't have png and zlib interfacing, samples do not deal with interpreted SPRITE data other than GsSPRITE, samples don't use cd threading, archives, or even special means to access the CD. You also forgot the part about PSY-Q, which is just illegal to embed and distribute, especially if connected to a product for sale, as you never got any license from Sony to do so. The more I read from you the less I believe there's anything really original in the sources.

    Caps can whine, yes, but I think the whine you hear out of basically all CRT comes from the Sync frequency.
