Wow, anonymous fceu savestates are discarded immediately upon loading? Snes9x savestates persist forever. (Not true since once the savestate object falls out of use, the Lua memory garbage collector eats it, but it's close enough)
You have a emu.framecount() function that links to movie.framecount()
Transparency as int [1] is deprecated and to be deleted at some point in the near future. In the meantime, it will still work. I don't know WHY I ever did that since I always had support for "clear".
You might want to check out gui.drawpixel, gui.drawpixel and gui.drawpixel
while (true) do
local input = {}
if (memory.readbyte(0) == 0x50) then
input.right = 1
end
-- do more stuff, optionally setting input.up=1, input.down=1, etc...
joypad.set(1,input)
FCEU.frameadvance()
end
rom.readbyte(1) should return the second byte of the ROM. Not the first. But I digress...
There should be a rom.header function if they want to include that. Hell, allow reading what kind of data it is putting out as well if they're going to be like that. Mirroring, mapper type, size etc.
Also, there should be a rom.writebyte too ;) That could coincide with the Hex Editor's real-time editing feature(s).
