But what is the last version v18 slim that has the 2.20 bios because I see some labeled SCPH-90010
should I be looking for a Scph 90005a or b or 9004a or b or so on...
it's not (a or b)
this is the date code which is composed of a number (which means the last digit of year of manufacture) and a letter (which means the quarter).
example: 7A = Date Code (January, February,March) of 2007
9D = Date Code (October, November, December) of 2009

not sure the date code

it's true that the majority does not have the date code, but to know if it is compatible with freemcboot, just testing it, is seeing the version of the bios with the appropriate program or trying to install freemcboot, no other way
