NTR

ntr's Issues

Makefile issue(?)

Seems due to the nature of bootloader.s, you need -pie passed to the linker. But that only solves half the problem. With -pie, the payload can run and everything is fine up till BootNTR says 'exiting...' then it crashes and ntr menu doesnt work.

Update GSP patch address for 11.6 to enable brightness control past version 11.3

from source/tools.c

line 651

 int GSPPid = 0x14;
int isGSPPatchRequired = 0;
uintptr_t gspPatchAddr = 0;
int bklightValue = 50;

int checkBacklightSupported() {

	
	Handle hGSPProcess = 0;
	u32 ret;
	u8 buf[16] = { 0 };
	static u8 desiredHeader[16] = { 0x30, 0x40, 0x2D, 0xE9, 0x00, 0x40, 0xA0, 0xE1, 0x01, 0x5C, 0x80, 0xE2, 0x8C, 0x01, 0xD0, 0xE5 };

	if (!(ntrConfig->isNew3DS)) {
		return 1;
	}

	ret = svc_openProcess(&hGSPProcess, GSPPid);
	if (ret != 0) {
		return 0;
	}
	gspPatchAddr = 0x0010740C;
	copyRemoteMemory(getCurrentProcessHandle(), buf, hGSPProcess, (void*) gspPatchAddr, 16);

	if (memcmp(buf, desiredHeader, 16) == 0) {
		goto requirePatch;
	}

	// 11.3.0
	gspPatchAddr = 0x0010743C;
	copyRemoteMemory(getCurrentProcessHandle(), buf, hGSPProcess, (void*) gspPatchAddr, 16);

	if (memcmp(buf, desiredHeader, 16) == 0) {
		goto requirePatch;
	}

	svc_closeHandle(hGSPProcess);
	return 0;

requirePatch:
	svc_closeHandle(hGSPProcess);
	isGSPPatchRequired = 1;
	return 1;
}

This would fix the brightness control not working in system versions past 11.3
