PS2 [MX4SIO/SIO2SD] SD Card Adapter and SD-driver for the PS2 SIO2 interface

[Fabio Kuntze]

@Fabio Kuntze This is amazing!!! Have you been able to get some SanDisk card working with the additional resistors?

i not have sandisk micro sd

 

[Fabio Kuntze]

Man, this is awesome! This also means that more SDs could be compatible without an MCU!

Hi @TnA!
some micro sd may have internal pullup and others not
PS2 MC and Joystick ports are open drain

Marvel vs Capcom 2 working!

If this works on a SanDisk card of my choice, I can send you the same card if you are in Europe.

Germany?

I am from Brazil.

My friend @Al3x_Portugal has Sandisk and SIO2SD adapter, I asked him to install pullup and test it, let's wait

 

[TnA]

That's a bit far. Damn postages and etc.

 

[Al3x_Portugal]

yes I will do the tests... I have sandisk class 10 and class 4...

games that worked with adapter modification:

Ps2 model 79001 + mod chip

**ZAPPER ONE WICKED CRICKET - SLUS_205.28
**SONIC UNLEASHED - SLUS_218.46
**SIMPSONS - THE HIT & RUN - SLUS_206.24
**MARVEL VS CAPCOM 2 - SLUS_204.86
**Space Channel 5 Special Edition
**Burnout Takedown - SLUS_210.50
**Need for Speed Underground 2 - SLUS_210.65
**shadow of the colossus - "Use VMC Slot 2"
**NFS most the wanted
**burnout revenge
**ICO


game suggestions to test?

Really nice! I never thought about that, because it's SPI. I know pull up resistors for I²C, but normally SPI doesn't need them. But of course, the interface is only "like" SPI, it is not SPI.

I will make a hardware update soon, but for now I don't have time for doing this. But it's good to know this BEFORE the hardware sale started

 

[TnA]

@Fabio Kuntze Please also ever add the model you have tested it with!

I can't wait for a trial with as many cards as possible @Al3x_Portugal!

Hi @Takeshi
It really rarely uses pullup in SPI, but in the case of the PS2, the ports work in open drain

ah ok, 79001 + mod chip, sorry

 

[BBsan]

@Fabio Kuntze So basically all signal pins (even the unused pins) should use pull-ups according to your link - correct?

Don't worry.
It is just important to mention, since it seems that compatibility along models can vary!

only 4 pins, DATA, CMD, ATT & CLOCK

Transcend 8GB MicroSD card working!!!!

 

[BBsan]

@Fabio Kuntze In the SanDisk SD card manual they say all other signal lines should be pulled HIGH, even if they are not used (like in SPI). I can at least confirm the fix does not work for my SanDisk 256Gig Card
About the same information is found here:
https://electronics.stackexchange.c...ard-via-spi-pull-up-resistors-or-dedicated-ic

I just ordered an SD card SPI breakout board that already has all the pullups in place. Gonna wire it up once it arrives

 

[Fabio Kuntze]

I used this breakboard, it didn't work in its original form
I ended up removing the integrated circuit and doing pullups with resistors
the other board connected with the Micro SD breakboard is a shift level, I installed it for testing, but it didn't offer any advantage.
I'll save this until I get my sandisk card for testing and debugging.

Don't worry.

I made new tests with a 79001 without modchip, with FMCB a lot of game incompatibility, a lot of games don't open or hang on the loading screen.
Conflict? RAM usage?

 

[Elrey_jj]

can i watch movies from a micro sd card and up to how many gb can i read on a ps2

and which ps2 do you recommend to buy?

 

[TnA]

1. Not yet, but it is technically possible.
2. 2TB
3. Depends on what you want to do.
