IMC on GC-SD HFW (emunand) #4
Comments
OK I thought it was like 3DS emunand but apparently not. Apparently only partitions necessary for OS function were redirected to the SD card (not even ur0). |
Depends what you redirected. I am pretty sure that the default version redirects all partitions/sectors after bootloaders. |
Doesn't look like so. That region only covers both |
Oh yeah! And if you want to redirect the MBR too just remove the sector 1 rw redirects. |
OK so I modified the script to remove the read/write conditions. My current MBR looks like this mbr.zip. Did I miss anything? |

Did you remove the sector 1 redirects? |
Yes I removed all the redirect conditions including the sector 1 special treatment (see https://github.com/dogtopus/psp2hfw/blob/full-redirect/scripts/sector_redir/sector_int2ext.c). I also synced both MBRs on my SD card but no dice. |
I am currently working on enso_ex v4.5 which is very different. |
Any more news on this? Would be great to install the whole system on the GC-SD |
Is this even possible? I tried to modify the MBR of emunand using mbrtool (after fixing some bugs that stopped me from making partitions > 4GB) but it doesn't seem to work. IMCUnlock modifies the sysnand instead.
The use case for this is pretty obvious: to reclaim leftover space on the emunand SD card so xmc will not be required at least when using emunand.
