Here's my Work-In-Progress script. Some stuff I planned is partly implemented but not working. There are ways to switch options around in massive quantities, but only a few of them can be switched individually at this moment. I'm using a way to handle input similar to what I did in this subtitles script. It works as a repeater for certain functions just fine. This is yet another rewrite of my Multitrack script. Hopefully, I've organized things even better than before. The rewrite is incomplete, but keeping it private wouldn't generate any interest in it (not as though posting it publicly here did any better...), so here it is now: Download Multitrack_DeSmuME.lua
Language: lua

I found a glitch with DeSmuME's frameadvance. Have this as the only piece of code: while true do emu.frameadvance() end Now run the one-line script and use the frame advance key. The emulator's frame counter will increment, but no actual emulation will take place. Pausing and unpausing the emulation still works fine, however. The window header of the version I'm using reads DeSmuME 0.9.6 x86.
