    Failed to remove the suicide battery of Segasonic

    I tried again with 10F1, 12F1 and failed :( and the game doesn't work also when the battery is attached and two roms are replaced. Maybe I have to replace 27c020 roms(EPR-15780, 15781, 15785) or use 27c210a rom instead of 27c1024

    Failed to remove the suicide battery of Segasonic

    I didn't know that =O I just swapped IC8 and IC17 and it didn't work again. There were no specific error message burning roms but maybe there were some problems while burning as you said. I have some other rom models (10F1, 12F1) so I'll try them

    Trackball Installation for SegaSonic with Original I/O Board

    I also think so, but trackball panel has only 8 wires per person (I think they're two 5V, two GND, XA, XB, YA, YB) so it doesn't seem to need 11p or 10p and I'm still a little confused..
