no way, because we don't design it to support other flash cart.

Now I´ve got the R6 Gold an reprogrammed it with Backup Master V1.18 with the Code from 1st Thread
The Nintendo Logo should be deleted now at Boot.
But the Card didn´t recognized anymore from DS
After flashing the R6 with Original Firmware it was recognized from DS.

Is there a Solution to flash this Code (with FF FF ...) in the R6 with recognized from Ds?

sorry for beeing a Pain. Do you know this Info. So I read it there is only Hex 15c urgent. So will it be possible to change 0C0 - 15B and will Checksum in 15c Original?:
  0C0h    9Ch   Nintendo Logo (compressed bitmap, same as in GBA Headers)
  15Ch    2     Nintendo Logo Checksum, CRC-16 of [0C0h-15Bh], fixed CF56h
  15Eh    2     Header Checksum, CRC-16 of [000h-15Dh]
  160h    4     Debug rom_offset   (0=none) (8000h and up)       ;only if debug
  164h    4     Debug size         (0=none) (max 3BFE00h)        ;version with
  168h    4     Debug ram_address  (0=none) (2400000h..27BFE00h) ;SIO and 8MB
  16Ch    4     Reserved (zero filled) (transferred, and stored, but not used)
  170h    90h   Reserved (zero filled) (transferred, but not stored in RAM)


For more info about CRC-16, see description of GetCRC16 BIOS function,
BIOS Misc Functions
For the Logo checksum, the BIOS verifies only [15Ch]=CF56h, it does NOT verify the actual data at [0C0h-15Bh] (nor it's checksum), however, the data is verified by the firmware.

Secure Area Loading Timeout (usually X=051Eh) used to initialize timer counter to (0-((X AND 3FFFh)+2)). (In case of Header checksum error it is ANDed with 1FFFh instead of 3FFFh, no idea why).
