Is there a way to program more modes like TGM’s rev mode or mono mode? If I knew more about the engine texmaster runs on, it might give me a hint of how to perform such a task. But it would be fun to try without having the trouble of an emulator.
Texmaster is closed source, so aside from reverse engineering the executable and hacking away at it that way, making updates to it is a no-go. @Report is the author, he comes and goes sporadically. Currently, it's hard to say how much he works on it or how much he'll continue to work on it.
Thanks for a reply, I thought it would be a nifty little idea that could embedded fun to experiment with. It would be cool to see something like that as well as maybe a promotional exam system like tgm3. Since authentic hardware is scarce and clones of tgm are introducing people to the series.
