DaedalusX64 is the continuation of the original Daedalus PSP port by StrmnNrmn and other contributors. It is a GPL Open Source project.

Changes:

[!] Rewrote R4300_SetSR ( Tom and Jerry, Extreme-G XG2, Powerpuff Girls and other games boot now !)
[!] Fixed misaligned in C0_SR ( Fixes camara to be zoomed in too far in Wayne Gretzky’s 3D Hockey ’98)
[~] Got rid off all CHECK_R0s in our R400 core….phhheww
[+] kernelbuttons.prx is built in proper location (froggyman)
[!] Updated debug pif tools, it compiles now against Dx64 source, also define was moved to config file for easy usage.
[~] Small code clean up…
