Hello, I am the lead developer of Rockbot, a homebrew game inspirated by megaman/Rockman classic games. The PS2 port is again working fine with sound and good speed, and any help or feedback is welcome.
You can grab the 1.0 beta 4 version here: Rockbot » Finally, beta4 is here!

As it is still a work in progress, expect bugs and unfinished stages and features, so please be a bit patient with it.
