My definition of a "fix" is "correct operation of the emulated hardware" (more than ever given that the hack for Segagaga is what broke VF3). We're trying to advance the (only) working public emulation of the AICA here. If you have patches or pseudocode or anything else that's helpful towards that end I'd love to hear it. "It's not as good as Makaron and I don't think it can be fixed" is not really what I'm looking for smile
