Re: MemCARDuino - Arduino Memory Card reader

FINALLY! got it working with my pc last night and am ecstatic. I plan to try it on my raspberry pi tonight

@shendo a few things

1st Thank you for such and amazing project.

2nd I am able to get both aftermarket memory cards to work just fine but the Sony memory card doesn't communicate with the ardruino. Any thoughts? All work with my ps1.

3rd I may have had an older version of memcardrex 1.8 but the MemCARDuino distributed with MCR 1.8 is the version that doesn't work with the newer ardruino SDK. Could you update the zip file. Took me an hour to figure out I had an older version lol.

Is that a ps1 controller/memory card interface? Also what else it on the board?

Hi soulgriever, I'm interested on this project of yours. How was it? Did you get to finish it?

Hello:

Where is the program and source code of the project to read the "Memory Card" of PS1 made with Visual C #?

Kind regards.

To Meta above: On GITHUB - its the first link if you google "memcarduino"

Ok guys - so I am here to basically make sure no one gets frustrated with this project, I appreciate the dev sharing it! A dexdrive is 70AUD at the moment - theres a new one on ebay - an arduino and parts laying around is, well 8 bucks for the Arduino clone free post.

In the end if time is money, I'd have been much better off with the dexdrive - but i finally have a working memcarduino for the cost of 8 bucks and some scraps. Well 15 (23 total) including the 9v USB Step-up cable.

so some points to make since the creator bailed on this:

I calculated the resistor dividers required to make use of resistors I had on hand - by using some in paralell and some in series I was able to get perfect 7.6v and a 3.8v (not sure what happened there! but the calculator showed 3.6). I split this off on the 9v USB cable to a little screw down barrel adapter - godamm it looked neat for what it was. Then came the frustration


The 1.9 version of the memcardrex comes packaged with an old INO file that won't do anything - use the one off github - im sure memcardrex 1.8 works fine too.

Clone arduinos need the CH340 driver and the "old bootloader"
If you use version 1.0.5 to write the INO off Github you won't need to select the "old bootloader" as the new one didn't exist yet.

The volages (I'm not sure how) are not correct

And finally,when he says Pin 13,12,11,10,2 he actually means D13,12,11,10,2 - if you connect via the arduinos Pin numbers, this is wrong.

I have LOTS of memory cards and none worked, genuine ones wouldn't read or write at all - nothing on the progress bar
Aftermarket ones would say they read and write but do nothing after completion.

So what got me suspect was on this thread is he mentions using 5v - but he says in multiple locations to use 3.6v (github, his project page, the PDF he made)

In the end what fixed it is removing the voltage dividers altogether and the power barrell / step up cable

use 5v in place of 7.6v - aftermarkets now work
use 3.3v in place of 3.6v - genuine cards now work

Best of all, you can grab these both straight off the the arduino, i have a double sided taped arduino sitting on top of a removed controller port/ memory card unit that wouldn't work in a PS1 (could have being the motherboard though)

Easy peasy

PS: no disrespect to the dev, this just drove me nuts and people may still be interested in these considering Tonyhax/ how easy it is to give yourself a trillion dollars and unlock everything in a save file using a hex editor. I was sick of using my PS2 to do everything, and having to switch between so many apps (i.e 2tb ULE breaks PS1 memcard compatiblity, launching memory card annihilator form a shortcut in the apps section of OPL makes it open in a different language than english and so on)

Man I couldn't make the circuit, I'm confused about the voltages, can you explain better how it made it work? or could you attach a photo of your project?

P.s.: I used a PS2 Memory Card
