Thanks notaz!
I noticed it earlier ... in case anyone else is wondering "what's new", from the readme:
QUOTE
rev 171
- Added optional "Accurate renderer", which is the original FCE Ultra
0.98.x renderer + PPU emulation code. It's much slower, but it can
handle games which need more precise PPU timing emulation (like
Marble Madness).
- Fixed saving and loading of game specific configs.
- Some other minor changes.
