Fix for int21h, ah=65h // GET NLS DATA

[jossk]

The int21h handler for func 65h do not check input buffer size :(

Quick fix for subfunc al=1 :

    case 1:
    {
        if (cpuGetCX() >= 41) {
            static const uint8_t data[] = {1, 38, 0, 1, 0, 181, 1};
            putmem(addr, data, 7);
            putmem(addr + 7, nls_country_info, 34);
            cpuSetCX(41);
        } else {
            dos_error = 1;
            cpuSetAX(dos_error);
            cpuSetFlag(cpuFlag_CF);
        }
        break;
    }
