You need a programmer cable, back in time we used make one with diodes and a DB-25 connector and send the firmware through Printer Port - no longer available in modern motherboards/laptops.
Can use original Mindaugas MJoy16 firmware or first versions of MMjoy (not MMjoy2) - not sure if still available for download.
Thank you Sokol1!! Sorry for late responce!
Might I ask one more thing?... Do you know what value and type of capacitor does the Thrustmaster FLCS shift register board uses? ... I see 3 resistor network 10K ohm 9 pins + 1 common, 3 HCF4021 chips and my C2 is missing. Thank you!!!
