How did I know the hater would pipe up early in this thread?
In case you couldn't tell, I was being facetious. I welcome a competitive build of Nestopia. After all, the original version was GPL, and the main goal of GPL is to allow anyone to make his own version of the software and to have access to other people's modifications, in the hopes of creating a better overall product. Although GPL has its definite disadvantages (as byuu explains in his recent posting on the BSNES site, which I personally recommend BTW), it can also do good things if the original author is okay with the consequences (as Marty is in this case).
Oh, and to the developer of the new build, please make sure the new version has an obviously different name, so that I myself don't cross them up (I'll probably have both versions on my computer).
