What do you mean with "bug fix" ? The original uses 127. From Ghidra:

            if (((cursor | i) != 0) && ((gMenuListCount - 1 != cursor || (i != 2)))) {
                    GUI_PrintString("SQL" + ((cursor + i) - 1 & 0xff) * 7,0,0x7f,(i << 0x19) >> 0x18,8,0);

If you mean a bug by QS, then I have the "fixes" branch for that. Fixes is rebased on v2.01.31 which is rebased on main.
I have fixed a few bugs in "fixes" that QS firmware (e.g. the 8.33kHz step for airband was not working correctly).

I'll test the "48" here and commit to fixes after the test.
