Here's the compiled build for those who want to test CakeHAX version of rxTools with the new GUI:
rxCakeTest.zip
(this includes the correct NDS file for installing MSET rop)
I swapped bottom screen offsets to make bottom screen work correctly from spider/mset entry points. I have not tested mset on 4.x. But I do know it works from 9.x if you downgraded MSET. (should boot fine from spider too)
This is pretty much what current rxTools source has but with CakeHax and few small tweaks added. Note that the bottom screen offset swaps are not present in my source code for the branch I compiled it from. I did a temp change for that to build this test build for MSET/Spider users. Ninjhax does not work with this build FYI. They will be fixing that soon hopefully.
BIN files in the "theme" folder go to rxtools/Theme/0 on SD card.
Would like to know if this boots on n3DS, but I don't think it will. The build they have working on n3DS may not be committed to their github yet. (probably because it's not done yet.
