Hacking R4i RTS Quad Firmware

[ThePowerOutage]

The too Cards with this GUI, namely R4 RTS v3.0 and R4iPT, the only system file (excluding usrcheat.dat) that has a different CRC32 and last modified date is the previously mentioned r4_firends.ext. I wonder why they are different.
Also, @gaborosm, do you mean the r4_firends isn't the file we are looking for?

r4_firends.ext is refer to load nds games (as you can see in its name). I mean we don't need to modify this file if we want to port it to R4i RTS. You can try it. Install the original R4i RTS firmware, and change the r4_firends.ext to the r4_firends of the R4iPT. In this way you will get an (ugly) R4i RTS which has same game compatibility as the R4iPT.

thanks!

Not at all! I would be happy when we successfully converted this firmware to R4i RTS and other M3 cards.

But I'm not sure about this is possible or not.

do not worry, the file is equal to what I can create! and does not work (white screen).
I think it's not just modify the file Flagrantia.okm but has also desired to make some changes in _ds_menu.sys

I don't know. One thing is for sure. If we can get the menu working on R4i RTS, the game loading will work. I have tried the r4_firends.ext with the original firmware and worked correctly.

the file loader.eng of R4irts run homebrew without any problem (just rename the homebrew to r4i.sys).
but the file's _ds_menu r4ipt not run homebrew, hence my conclusion!
