By total coincidence I was trying to achieve that exact thing today and this seems to work (but I didn't test it together with the char board yet, so I'm not sure if this is 100% correct).
Add this to the rom_gen.py at the start:
Code:
# IQ_132 dual version
"0811e99e866a417d7eb30308b405d2f79ff22c0d2047ea7d31b8a0b8f6b6b99e": ( False, False, True, ((0x00000, 0x400000, "ddp3_rg/ddp3_p1_iq132.bin"),)),
Get the introless bios from this post (this is the gladiator, not ddp3, not sure it makes a meaningful difference?):
Here is the test BIOS.
Enjoy.
T.
Then run this on the bios and the ddp_j.bin:
Code:
python3 rom_gen.py -b pgm_bios_single_pcb_vxxxJP.u42 ddp_j.bin
... and this should generate "ddp3_p1_iq132_qb.bin" which worked for me at P1 to go straight to the dual menu, but let me know if this doesn't look like the right approach
