ant512 has released a chuckie egg type game for the GBA:

PypeBros kindly created a title screen for Professor Sinister, so heres a new release:

In addition to the title screen, this latest version includes some bugfixes, tweaks to the music and improved audio quality.

Get in touch if you have a way of getting the ROM onto one of those cheap reproduction carts that folks sell on Etsy. Id love to have a physical copy of this on a dedicated cart.
