更新一下假3.55的payload。虽然觉得这个更新意义不大。还是发下吧。也许有人需要。

How I can include this code in my lpc2148 for downgrade de firmware?

source of ps3yes for downgrade the ps3:

psgrade.c

JIG_Task:
void JIG_Task(void)
{
static int bytes_out = 0, bytes_in = 0;
... ... //prepare the response
HMACInit(jig_key,20);//place HMAInit here and delete it from main
jig_challenge_res[1]--;
jig_challenge_res[3]++;
... ...
Endpoint_Write_Stream_LE(&jig_challenge_res[bytes_in], 8, NO_STREAM_CALLBACK);
//Fix the bug
}
main:
int main(void)
{
SetupHardware();
//HMACInit(jig_key,20); //move to JIG_Task otherwise cause problem on some boards.
LED(~GREEN);
state = init;
switch_port(5);//modify switch_port(0) to 5, with the same reason.
...... }
key.h
//Add the key
const uint8_t jig_key[20] = {
0x04, 0x4E, 0x61, 0x1B, 0xA6, 0xA6, 0xE3, 0x9A,
0x98, 0xCF, 0x35, 0x81, 0x2C, 0x80, 0x68, 0xC7,
0xFC, 0x5F, 0x7A, 0xE8,
};

psgroove and psgrade use lufa usb lib to make it work on AT90USB and related MCUs

lpc2148 and other arm cpu can not use lufa lib.
so it is not so simple to modify the lpc2148 psgroove code as psgroove -> psgrade
this lpc2148 psgroove is build using keil MDK.
if you have the source code of this, you need to modify main.c, usbuser.c and usbcore.c , find the similar place, and make it look like the psgrade(ps3yes also use it).
download psgrade source , add sha1.c sha1.h hmac.c hmac.h key.h to lpc2148-psgroove source. you may need to modify the data type to make it work.

my ps3 ver is 3.41,  i do not need to downgrade, so i do not make it.

能一下这个payload对应的port1_config_descriptor.h么？我的LPC2148版本不是ICDEV的，需要自己编译。谢啦！

你好，我是一个ps3爱好者，我很敬仰你能够把psgroove 移植到lpc2148上运行，我多天仔细研究2148代码和psgroove代码，我现在想把它移植到stm32f103这款芯片上，为此我为了熟悉stmusb库，学习了两个星期的usb库，现在正在进行ps3的破解移植，主要是参考你的lpc2148的方式，现在遇到点困难，希望你能够点拨指导，谢谢

现在有给PLC2148用的降级PS3系统的固件吗
