The Trace Viewer in action after running my profiler script in Tcl.

I created a profiler with some lines of Tcl script thanks to OpenMSX new Trace Viewer. It's easy to use and doesn't require the programmer to insert INs and OUTs in his code, so it works with old ROMs too. #openMSX #msx #tcl #debugging #gamedev #profiler #homebrew #8bit

#Gaurodan is out!

The 2013 game has been completely redone to fit my current vision of traditional arcade game design. It's denser (more levels but less overall length), with better pacing, mechanics and a proper scoring system.
