From a MkIII perspective, anything V22 and newer are all the same and will take your drive to 3-1/63. See

One suggestion would be to try to go down to V21 and then update to a hacked version of V22 or higher to give you the languages you are looking for.
One note of caution. MkIII's are notoriously more vulnerable to not being recoverable from a bad OS load as compared to the MkIV. Use extreme caution with a MkIII.
