What is your IBAN?
Australia does not use an IBAN to receive funds. If you’re in doubt, please ask your bank for assistance on how to send money to an Australian Bank Account.
What’s the difference between ‘PSIO’ and the ‘PlayStation Classic’?
The PlayStation classic is a software emulator which contains pre-loaded games which can not be changed, nor can you load any of your own games on it (unless you hack it). Using it for development is also not a possibility. You can’t also use your original Memory Cards to save games and other peripherals such as light guns and racing wheels will not work.
With PSIO however, you are free to backup your discs and play them as originally intended on the original hardware. You can also use your genuine Sony peripherals which you may own from the original console released in 1994. Overall, PSIO offers a whole lot more whilst giving you the true classic PlayStation experience the way it was meant to be.
How many games can the Menu System support?
Currently the maximum limit is 1000 games.
What is PSIO?
PSIO is simply a development cartridge that plugs into your PlayStation’s Parallel I/O Port. It allows you to instantly see your software running from an SD Card on real hardware, making it the ultimate developers tool, as well as making it invaluable for debugging. It is only for PlayStation 1 consoles that bare the Parallel Port I/O connection.
Is PSIO an emulator of PlayStation software?
PSIO does not emulate PlayStation software. PSIO is an emulator of the CD-ROM co-processor (SUB-CPU). That being said, it is a hardware emulator, which, is almost identical to the original Sony CD-ROM MCU.
What is the total height of the PlayStation with PSIO installed?
78 millimetres or 3.07 inches.
Is PSIO the same thing as an ‘EverDrive’?
Yes. PSIO is essentially a Flash Cart.
Is PSIO faster than a regular CD-ROM?
Yes. The data streams at the original data rate of a CD-ROM, but because there are no seek times, data rate failures or seek/spin-up times, this is where the huge increase in speed is.
Why is PSIO so expensive?
High quality custom designed and developed products aren’t cheap to manufacture, market and sell. Also, in comparison to other Flash Carts on the market, ours is at a very good price point.
How compatible is PSIO with the PlayStation software library?
Out of all official 2,435 software titles, PSIO is so far 99.8% compatible (as of 15/JUNE/2018). For more detailed information, please see our ‘Compatibility‘ database on JIRA. If you’d like to work this out manually, take all the games listed in JIRA that do not work, and minus it by the total amount of PSX games (2,435). Then, divide those two numbers and get the percentage (example).
Assuming each game is 650 MB, how many games can PSIO fit?
Note that not every PlayStation game is 650 MB, so you may be able to fit a lot more games than the table below based off of the math formula ((SD SIZE * 1024) / 650). Also, take into account that each MULTI-DISC image should be treated as a separate game.
– 8 GB will fit ~12 games.
– 32 GB will fit ~50 games.
– 64 GB will fit ~100 games.
– 128 GB will fit ~200 games.
– 256 GB will fit ~400 games.
Who made PSIO and where is it manufactured?
PSIO was developed and designed in both Australia and Russia by Cybdyn Systems. Whilst PSIO is assembled in Australia, the parts required to assemble the cartridges are manufactured in China.
I purchased a ‘Mainboard Modification Service’. Where is your address?
Please login to your account by hovering over the ‘Support’ tab and clicking on ‘My Account’. Alternatively, please click here.
I want to change my shipping address. How do I do that?
Please login to your account by hovering over the ‘Support’ tab and clicking on ‘My Account’. Alternatively, please click here. Once logged in, simply edit your ‘Shipping Address’. Note that it will change to your new address once we manually update your order (which will be when we process it for shipment).
Is there any input latency when playing games on PSIO?
No. Take note though that if you use a CRT (Cathode Ray Tube) TV which the PlayStation was designed for, there will be almost zero latency. However, if you use a modern day LCD (Liquid Crystal Display) TV, most if not all have high-latency which will effect your gameplay, especially in games which require precision input, such as Tekken 3, Gran Turismo or Bust a Groove. This has nothing to do with PSIO however since PSIO runs games at the original full speed they were intended to be played as.
Are there any modifications required for PSIO to work?
Yes. An internal modification is required. We have developed a small printed circuit board (PCB) that detects whether a PSIO cartridge is plugged in or not and routes two very important signals to the Parallel Port (Sony never did this for us when they designed the PlayStation unfortunately). We have called this little device, the “Switch Board”. The Switch Board consists of nothing more than a 4066 Quad Bilateral Switch, a few resistors, a diode and a capacitor. More information may be found here, including the circuit diagram.
I don’t want to modify my PlayStation!
If you don’t want to touch your original console for nostalgic reasons, we suggest buying a second hand console and using it instead to have the Switch Board installed into. That way your original console stays the same and you have a used second hand unit to modify and play on.
Why doesn’t PSIO have a “CE” or “FCC” certification?
The “CE” and/or the “FCC” certifications do not apply to us since we are an Australian registered company selling in Australia. It is your responsibility as the consumer to check the laws of importing an electronic device without the said certification(s). Note however that these licenses are mostly there to check the product that is being sold to the the consumer is safe and will not cause harm to you or other electronic devices (mostly to do with radio frequency and high levels of electromagnetic interference).
PSIO was designed with the highest quality components and with safety as the top priority. It is extremely low powered and the electromagnetic and radio frequency activity is also extremely low. Here is a spectrum analysis output of the noise levels from PSIO. At a distance of 1 centimeter from the top front side of the circuit board, the noise levels are 30 decibels (peak). On the reverse side, it’s 15 decibels (peak). You can also see some spikes in the image below, and this is when the system clock line is pulsed. They are about every 50 megahertz with the weaker ones every 25 megahertz. The peak is around 300 megahertz which seems to be emitted from the ARM microcontroller.
What are the exact PlayStation models that are compatible with PSIO?
Please see here.
Is the Switch Board a modchip, and will it let me boot copies of my software?
Do Link Cable games work?
Yes, even if you have one PlayStation console running a game from PSIO and another from a CD-ROM.
How do you pronounce PSIO?
“Sigh-Oh” or “Psy-Oh”. It’s abbreviated for “PS1O” (the “I” is actually a roman numeral).
You guys know that there is a company that makes glasses with the same name, right?
Sure do! They copyrighted the word “PSIO” (all English letters), but our logo actually contains the number 1 (one). The “I” in our wording/logo for “PSIO” is actually a roman numeral, which for us, makes “PS1O”. As for the term “PlayStation Input Output”, this has nothing to do with the abbreviation of the word “PSIO” and is just a string of coincidental characters.
How much is shipping for a PSIO cartridge?
It is free, and included in the total cost mentioned above.
Do you post Worldwide?
Yes. We ship to almost every country.
Can I pay by PayPal?
No. We refuse to use their services.
Can I buy PSIO off of eBay or Amazon from you guys?
No. We only sell PSIO under our companies name (Cybdyn Systems) and/or through selected distributors.
What payment methods are available?
The only payment methods available are Credit Card (via Visa and Mastercard), Bank Transfer and upon special request, Bitcoin.
How do I select my software images?
When an SD Card with the correct file is inserted into PSIO, a custom built Menu System boots up each and every time you turn on your PlayStation. This is called the “PSIO Menu System”. This Menu System runs on the PlayStation hardware directly, and allows you to select and boot software from the SD Card using the controller. Demonstration images of the Menu System running can be found under the ‘Features’ tab.
How many lines of code does the PSIO Menu System consist of?
There are just under 40,000 lines, all hand written from scratch for the Menu System, Fastboot logic and System Loader. The FPGA and ARM logic consists of triple that amount.
Can I skip the PlayStation ‘BIOS’ and ‘License’ screens with PSIO?
Yes, you can toggle an option in the Menu System to enable or disable such a feature. For more information, please read the ‘Systems Manual’ (available on our ‘Downloads‘ page).
Can I boot my original PlayStation format CD-ROM’s like normal when PSIO is plugged in?
Yes, so long as the Switch Board has been installed correctly, there is an option in the Menu System to boot from the CD-ROM drive directly. You may also simply unplug your PSIO cartridge to return your PlayStation back to regular stock-standard operation.
Can I control the Menu System with the ‘GunCon’?
Can I control the Menu System with the ‘Mouse’?
Will my Xplorer and or Action Replay cartridges work like normal when plugged in?
Again yes, so long as the Switch Board has been installed correctly, you may unplug PSIO and plug in your other game cartridge where it will then function perfectly normal.
Will DUAL-SHOCK Vibration and Memory Cards work?
Yes. All official licensed Sony (1st party) peripherals will work normally with PSIO.
Will PlayStation titles run at their original speed when using PSIO?
Yes. The PlayStation Parallel Port can handle up to 3 megabytes per second on the system bus. The original CD-ROM (at 2x speed) could read at a maximum of 352 kilobytes per second, so there is plenty of bandwidth available.
Will the PlayStation ‘Power Supply Unit’ (PSU) overload/overheat with PSIO?
No, even if (hypothetically) your cartridge somehow developed a short circuit, the internal fuses on the PlayStation’s voltage rails would go open circuit before any hazard or fault is even perceived.
What regions does PSIO work in?
It will work in all regions. This includes PAL, NTSC-U/C and NTSC-J.
Do all software titles work on PSIO?
Not all software will run, and we are unsure what ones will fail without testing of each and every software title in its library.
With that being said, usually we can fix the problem with a firmware update if you let us know the exact problem.
You may however see what software has been tested here.
What format should my software be?
We recommend that your CD-ROM discs are ripped 1:1, without any errors whatsoever, as a *.BIN and *.CUE format. Other formats you may use however are *.ISO and *.IMG.
I see that my software title isn’t listed in the ‘Compatibility’ page. Will it work with PSIO?
Yes, your software title should work with PSIO. If your software does not work, please let us know, and we will flag it in the Compatibility section for others to know about. We will then start to look into it to try and resolve the issue when we can.
My console doesn’t have a modchip. Can I use PSIO to boot copied games?
No. We don’t allow it for legal reasons. We could enable such a feature however since we know how to get around it obviously, but we wont.
My PlayStation is a PAL system. Can I run NTSC-U/C or NTSC-J software on it?
Yes, however you will need to play over RGB video output. Otherwise, you will need to do a modification to the PlayStation mainboard in order to generate the correct colour frequency for your TV to accept and display an output correctly.
I have/had a modchip previously installed in my PlayStation. Will that cause any problems?
Do Multi-Disc games work okay?
Yes. You can complete games which use multiple discs since PSIO supports real-time disc swapping. Please read our ‘Systems Manual’ for information on how to set this up.
Can I watch movies/video?
You can watch video as a Sony STR format in a resolution of 320×256 at 15 Frames per Second in Stereo with 44.1KHz audio (MPEG frames interleaved with XA).
Can I use a Hard Disk Drive to play my software?
No. The USB port on PSIO is to stream software image data from a PC only.
What about the PSone (SCPH-100) and or SCPH-9000 systems?
The PSone and SCPH-900x series will not support PSIO since they do not have a Parallel I/O port. However, we have had a lot of people ask if we offer such an option, so we may develop a special version that will not include the PIO header connector on the PCB. It will essentially just be a circuit board with an SD Card slot that you can solder to your PSone or SCPH-900x series PlayStation. However, you will be required to solder 40 wires from this special version of PSIO to the PSone or SCPH-900x mainboard manually. When we have news in regards to this, we will announce it, so please don’t ask us when we will be making it.
When did you start working on this?
PSIO began as a concept on August 15th, 2010. The first prototype was then made in 2012. What we have created is a ‘one of a kind’ device, and nothing else exists like it. A lot of work has gone into PSIO (especially the polishing aspect), so we hope you will enjoy it.
I can play my original games fine on my PS3 or PS4. Why would someone buy this?
The PS3 and PS4 emulate the entire PlayStation hardware using a software processing technique instead of direct hardware. It is inaccurate and glitchy with high latency response times, and the PlayStation titles were never designed to be played like that. Many users have problems when playing them.
What is the point of this product?
The PlayStation CD-ROM drive when brand new was decent quality. However, since the systems launch in 1994, the laser assembly has deteriorated, and it is impossible to find a brand new one since they are no longer made. The ‘new’ ones available online are fake, low quality replicas. Since then, software now freezes, music skips and sometimes games will not load anything at all due to this fact. PSIO removes all of these problems, and also decreases the load times dramatically since there are no more moving parts, and we have faster available bandwidth on the parallel port. With PSIO, you can literally shake the PlayStation console whilst playing a game and it will not skip nor freeze.
