From 7dbded99a22cad84772490baee9d4913c4d1987e Mon Sep 17 00:00:00 2001 From: Aurora Date: Mon, 11 Apr 2016 05:15:44 +0200 Subject: [PATCH] First commit of the AuReiNand rewrite! - Gotten rid of the patched FIRMs, AuReiNand now finds and loads all the FIRMs from CTRNAND by default. If you are booting an emuNAND, the FIRMs will be loaded from its CTRNAND. This also applies to AGB and TWL FIRM, and allows for a very fast boot with no firmware files on the SD card. - If for some reason (like using NTR) you do not want to use the CTRNAND FIRM, you can place a firmware.bin in the aurei folder and it will be loaded just for the default NAND. - The way AuReiNand works has changed. Now you can specify to autoboot SysNAND or not, and a NAND is no more tied to a FIRM (since 9.0 FIRM is autodetected). If you press nothing the default NAND is booted with its own FIRM, L boots the non-default NAND with its own FIRM, R boots EmuNAND with the SysNAND FIRM if you picked "Updated SysNAND", and vice-versa. - In order for AuReiNand to handle FIRM reboots, the .bin path needs to be hardcoded in the program. The default is /arm9loaderhax.bin (the AuReiNand.dat is also supported for 9.0 people). A PC tool was written to make changing the path easier. - Bug fixes and stuff I forgot. - Gelex is a saint. --- .gitignore | 1 + Makefile | 10 +- injector/source/patcher.c | 10 +- patches/reboot.s | 136 +- pathchanger/pathchanger.c | 98 + source/config.c | 25 +- source/config.h | 4 +- source/crypto.c | 189 +- source/crypto.h | 39 +- source/emunand.c | 6 +- source/emunand.h | 2 +- source/fatfs/diskio.c | 46 +- source/fatfs/ff.c | 9372 +++++++++++++++++----------------- source/fatfs/ff.h | 700 +-- source/fatfs/ffconf.h | 547 +- source/fatfs/integer.h | 66 +- source/fatfs/option/ccsbcs.c | 348 ++ source/fatfs/sdmmc/common.h | 3 +- source/fatfs/sdmmc/sdmmc.c | 41 + source/fatfs/sdmmc/sdmmc.h | 1 + source/firm.c | 532 +- source/firm.h | 11 +- source/fs.c | 64 +- source/fs.h | 4 +- source/main.c | 19 - source/screeninit.c | 18 +- source/start.s | 29 +- source/utils.c | 10 - source/utils.h | 1 - 29 files changed, 6452 insertions(+), 5880 deletions(-) create mode 100644 pathchanger/pathchanger.c mode change 100644 => 100755 source/fatfs/ff.c mode change 100644 => 100755 source/fatfs/ff.h mode change 100644 => 100755 source/fatfs/ffconf.h mode change 100644 => 100755 source/fatfs/integer.h create mode 100755 source/fatfs/option/ccsbcs.c delete mode 100644 source/main.c diff --git a/.gitignore b/.gitignore index da6e2f3..29fb8eb 100644 --- a/.gitignore +++ b/.gitignore @@ -1,6 +1,7 @@ out build loader/build +screeninit/build injector/build *.bin *.3dsx diff --git a/Makefile b/Makefile index 2040ddf..e5036c3 100644 --- a/Makefile +++ b/Makefile @@ -42,6 +42,9 @@ ninjhax: $(dir_out)/3ds/$(name) .PHONY: release release: $(dir_out)/$(name).zip +.PHONY: pathchanger +pathchanger: $(dir_out)/pathchanger + .PHONY: clean clean: @$(MAKE) $(FLAGS) -C $(dir_mset) clean @@ -54,6 +57,9 @@ clean: $(dir_out): @mkdir -p "$(dir_out)/aurei/payloads" +$(dir_out)/pathchanger: $(dir_out) + @cc pathchanger/pathchanger.c -o out/pathchanger + $(dir_out)/$(name).dat: $(dir_build)/main.bin $(dir_out) @$(MAKE) $(FLAGS) -C $(dir_mset) launcher @dd if=$(dir_build)/main.bin of=$@ bs=512 seek=144 @@ -108,9 +114,9 @@ $(dir_build)/%.o: $(dir_source)/%.s $(dir_build)/fatfs/%.o: $(dir_source)/fatfs/%.c @mkdir -p "$(@D)" - $(COMPILE.c) -mthumb -mthumb-interwork -Wno-unused-function $(OUTPUT_OPTION) $< + $(COMPILE.c) -Wno-unused-function $(OUTPUT_OPTION) $< $(dir_build)/fatfs/%.o: $(dir_source)/fatfs/%.s @mkdir -p "$(@D)" - $(COMPILE.s) -mthumb -mthumb-interwork $(OUTPUT_OPTION) $< + $(COMPILE.s) $(OUTPUT_OPTION) $< include $(call rwildcard, $(dir_build), *.d) diff --git a/injector/source/patcher.c b/injector/source/patcher.c index 43ccb52..b99a914 100644 --- a/injector/source/patcher.c +++ b/injector/source/patcher.c @@ -187,18 +187,18 @@ void patchCode(u64 progId, u8 *code, u32 size) case 0x0004001000027000LL: // KOR MSET case 0x0004001000028000LL: // TWN MSET { - if(R_SUCCEEDED(loadConfig()) && ((config >> 5) & 1)) + if(R_SUCCEEDED(loadConfig()) && ((config >> 4) & 1)) { static const u16 verPattern[] = u"Ver."; - const u32 currentFirm = ((config >> 12) & 1); - const u32 currentNand = ((config >> 13) & 3); + const u32 currentNand = ((config >> 16) & 3); + const u32 matchingFirm = ((config >> 18) & 1) == (currentNand != 0); //Patch Ver. string patchMemory(code, size, verPattern, sizeof(verPattern) - sizeof(u16), 0, - currentNand ?
