Χαἰ?ετε, ὠ Τεξτκἰτιοι! I’m trying - after a break of a couple of years - to get my Greek going again. But I’m having great difficulty with remembering those δεινο?ς irregular verbs… Has anyone written software to test irregular verbs? I use the Eton Greek Project software for morphology practice, but irregular verbs are getting me down a bit 
Can anyone help?

I’m not sure this is exactly what you’re looking for, but you might want to check out some of the verb practice drills at http://socrates.berkeley.edu/~ancgreek/ancient_greek_start.html.
For an offline resource, a standard grammar like Goodwin or Smyth has a list of the most important irregular verbs and their principle parts. You could access it from the Textkit archives and print off the relevant pages, and even make your own flash cards if you are so inclined. Just a thought, N.
I would try Kalós, a free verb conjugator software
Which does both canonical-to-conjugated (inflection) and conjugated-to-canonical (morphological analysis).
It is the best software there is, for what you are looking for

Sure it is available offline: I bought a CD version of the site years ago. Check the home page. Ordering info is right there.
You should try Mastronarde’s site again, and go to the Verb Drills. Irregular verbs will pop up from the beginning (unlike in some textbooks), and you’ll get a lot of verbs thrown at you. the Mastronarde website is also available on CD.
If you feel like you have dealt with all that site can throw at you, try www.gottwein.de for some pretty intense morphology pages.
After that - well, when you open any text at random, you’ll see lots of verbs with irregular principal parts (note the spelling:-))..
