- Add dram_fuse.c/h for shared fuse-to-MiB mapping - After successful update/clean install copy: if hekate_8gb.bin exists and fuse reports more than 4 GiB, copy to sd:/payload.bin and sd:/bootloader/update.bin, then remove source; otherwise remove helper only - Makefile: make ram-test builds output/RAM-Test.bin (tools/ram_test_main.c) Made-with: Cursor
