It is time to stamp out those lurking bugs: this weekend marks the beginning of unit-testing season for magic-rw and thus Magic.TXD! Me and my girlfriend will be carefully inspecting the capabilities of each native texture (D3D8/9 especially) to make sure that each reasonable one gets accepted and each obviously wrecked one rejected by the tool. We will be using a specially crafted tool called "rwchunk-writer" to accomplish our goals: commandline user interface for writing binary-coded RW bitstreams.
You can find rwchunk-writer here: https://osdn.net/projects/eirsamples/releases/
