The entire EQEmulator code is years of individual's work all combined to make a single final product. There have been hundreds or maybe thousands of code additions to the source and they all came from unpaid volunteers to the project. No doubt some of it isn't perfect. Some of it was rushed to get it working and then never tweaked or corrected to work the right way. Reading the source there is alot of comments like "I don't know what is going on here..." and "I am too lazy right now to do this the right way", etc lol. The emulator is a huge project and for a small community to put something together over the past few years that works as well as it does is pretty amazing to me. My point is that it sounds a little like you are putting down the coders that wrote the source. Yes, some parts aren't perfect, but with limited resources and no paid professionals to work on it, I think the project is a huge success considering it's current state. This is probably the best emulator community and most complete emulator code in the world. So, we must be doing something right
If you are a good coder, then you are more than welcome to have at fixing any part of the code you wish to work on. The code will have to be checked and approved by the developers of the project before it gets added. But, if it is a good fix or good code, then it should definitely make it into the source. I hope to see some code from you if you have time and are interested in trying to help the community
