PS2 MX4SIO hybrid MCFS & FAT32 at the same time

[Berion]

I've got already MX4SIO, yet without the case, so still, it waiting for it's great moment. But meanwhile I read about it and peoples says that MX4SIO hang OSDSYS/HDD OSD.

I don't know if those freezing/crashing problems comes from fs parsing which failing of course as it is unknown to them, or some hardware communication issue with MCSIO. But let's assume for a while that this is only a matter of filesystem.

To solve that, user could write on first 8MiB (with or without ECC? without let's say starting from 0x0 to 0x7FFFF0) standard MCFS covering 8MiB, and the rest space could be formatted as FAT32 (on Linux, using loop from sector range, then mkfs.vfat on it). This would also needs changes on OPLs BDM side to start from 0x800000 (without partition table). Oh, and another changes for game installers like USBUtil (which is great coincidence that @ISEKO works currently on v3.0). But with such forged SDHC card, user would have standard Memory Card functionality and games to read with OPL from the same media. Of course if my assumptions are correct... Well, just an idea. ^^

MX4SIO didn't hang on the OSDSYS for me at any time.

It can't read the FS in the first place, because it can't even identify the device without additional software. So no... That is not the problem.

We can use VMCs on it and that already works.

Why? What's the difference between MX4SIO and butchered PS2MC with replaced NAND by card reader?

Yes, and that's obvious. But assumption was that MX4SIO hangs on boot with it inserted and inside storage browser in OSDSYS/HDD OSD. In addition, Sony software cannot reads VMC.

If this could works, would be awesome to have such hybrid storage. If. ;p

The difference is, that a PS2 MC has an MCU made to "answer" to the PS2 and an SD card does not.

Sadly, there is no "if". :-|

What is "MCU"? :P

 

[TnA]

Obviously it is not related to "Marvel".

"Microcontroller"
