Tiny Multi Bootloader+ / Discussion / Ask for Help: Bootloader for PIC18F97J60

Hello,

I use pic18f97j60 device and Tiny Multi Bootloader+(v0.10.0 or v0.11.0).
I use XC8 and mplabX.
I has modified tinybld18F24J10_ext16MHz_19200.asm to use with 18f97j60, and add new entry to piccodes.ini.
I build a simple program, set Memory model to 100-500, and try to use Tiny Multi Bootloader+ to send firmware to pic, but I get this errror:
Error: hex file too large, writing bootloader firmware!!!
ERROR: Problem in uploading HEX file to device

Can you help me, please.

Here is my .hex file
