This micro sd slot has a switch that goes to GND when a card is inserted, I connected the ACK pin. if I remove the card, the ACK pin is disconnected from the GND, and then I have port 2 free for memory card

a 10k resistor only, the 47r one can go to GND

It's always on, this version is January, but for me it's the best we have in compatibility and stability with the MX4SIO

try this https://www.psx-place.com/attachments/opnps2ld-v1-1-0-beta-1629-e20f2ee-bdm3-zip.30235/

It's the same method as USB, I recommend using the USBUTIL program to put the games on the card.

your diagram is correct. you can test another micro sd micro sd sandisk don't work

Has anyone tried to use the MX4SIO on a ps2 with multitap? https://hackaday.io/project/170365-blueretro/log/186471-playstation-playstation-2-spi-interface With the popularity that the project has been reaching in the last few weeks, I won't be surprised to find this for sale on Aliexpre$$...

in my tests everything is fine, working under the same conditions as the configuration with 4 resistors. I always use Burnout and NFS games to check my experiments. . tested with 39001, 70001, 77001, 79001 and 90001, all with mod chip and I don't see a difference, it worked the same on all...

Exactly, I checked the ps2 service manual and found that it has onboard pullup on some pins.

my current adapter: the optional 47R resistor and can connect the ACK pin directly to GND without any problem. The pullup only on the DATA pin, the other pins already have a pullup on the ps2 board. a topic about compatibility is important, but for now I see that game compatibility...

Good night @TnA The news on this topic in recent days are the best, I'm very optimistic about this project. Here in Brazil the project is already starting to gain popularity, we already have many youtubers commenting on and building adapters, I am part of a PS2 group and I am helping many...

alternative adapter with common and cheap material

I tested the OPL 1703/DB2027 version and found a lot of problems with the BDM drive. It doesn't save the settings in the Micro SD, and doesn't load them on startup, after setting BDM it recognizes and loads the Micro SD game list, but from 5 games I have only 1 started...

Alternative adapter, requires soldered wires on ps2 board or some connector compatible with MC port UPDATE 08/04/2021 Add 10k resistor from MISO(DAT) to 3.3v(VCC)
