To date I have just messed around a little with Intuition and hacked it to create a crude pong game named wbpong which is downloadable and playable directly: which is slow on default mode but you can use one of the following:
wbpong [normal|hard|harderer|insane|wtf]
Yes, this thing does not have a click-able icon, so you have to be in the same directly where `wbpong' resides and run one of the commands (see above).
I hope to do more soon. I do not really have a great amount of time these days and I am trying to learn more about 68k assembly.
Hope you enjoy!
