Hacking PyGecko coreinit.rpl OSLogRetrieve

[H0neyBadger]

Hello,
I try to translate the rpc.py’s get_logs function into PyGecko call.
But the log size is always null "0".

import struct
from binascii import hexlify

tcp = TCPGecko("192.168.1.100")

def get_logs(filename='logdump.bin', save_addr=0x1e800000):
    address = save_addr
    for x in range(0,32):
        tcp.pokemem(address, 0x00000000)
        address += 4
       
    #OSLogRetrieve = tcp.get_symbol('coreinit.rpl', 'OSLogRetrieve')
    #result = OSLogRetrieve((1<<11)|(1<<12), save_addr, 0x01000000)
    result = tcp.function('coreinit.rpl', 'OSLogRetrieve', False, 0, (1<<11)|(1<<12), save_addr, 0x01000000)
    size = int(hexlify(tcp.readmem(save_addr, 4)),16)
    print("OSLogRetrieve result:{0}".format(result))
    print("OSLogRetrieve size:{0}!".format(size))
    logs = []
    if size:
        for addr in range(save_addr, save_addr + size, 500):
            print(addr)
            logs += list(tcp.readmem(addr, 4))
            print(logs)

        dump = open(filename, 'wb')
        for word in logs:
            print(word)
            dump.write(struct.pack(">I", word))
        dump.close()


get_logs()
tcp.s.close()
print("Done.")

Did I miss something?
