The console type field can be very strange, especially with older pre-1888 dashboards, for example two different 1838 keyvaults identify their console type as 0x80000002. If you want to check if something is devkit or retail, I'd suggest something like:

if(consoletype == 0x02)
    return retail;
    return devkit;
