As I remember, the debugger is turned off by default in the source code. If you want to turn it on, you have to find the spot in the code to change it from off to on.
As you all seem to have compilation problems i am posting the executable of pj64 with the debugger. This way you will be able to discover another part of this fabulous emulator !!
Rename the first archive to project64debug.exe
and the second to project64debug.c00
With this debugger ¿Can we locate and know how dows work the algorithm for the compression of the 2D graphics in Evangelion 64 and Resident Evil 2? j64:
Ill check it out. Maybe in a few months, a GFX plugin can be released (Alpha Ver.). Or even a utility that decompress tha data and leave it right to Rom translation.
