byuu says: Note: for Windows users, please go to nall/intrinsics.hpp line 60 and correct the typo from "DISPLAY_WINDOW" to "DISPLAY_WINDOWS" before compiling, otherwise things won't work at all. This will be a really major WIP for the core SNES emulation, so please test as thoroughly as possible. I rewrote the 65816 CPU core's dispatcher from a jump table to a switch table. This was so that I could pass class variables as parameters to opcodes without crazy theatrics. With that, I killed the regs.r[N] stuff, the flag_t operator|=, &=, ^= stuff, and all of the template versions of opcodes. I also removed some stupid pointless flag tests in xcn and pflag that would always be true. I sure hope that AWJ is happy with this; because this change was so that my flag assignments and branch tests won't need to build regs.P into a full 8-bit variable anymore. It does of course incur a slight performance hit when you pass in variables by-value to functions, but it should help with binary size (and thus cache) by reducing a lot of extra functions. (I know I could have used template parameters for some things even with a switch table, but chose not to for the aforementioned reasons.) Overall, it's about a ~1% speedup from the previous build. The CPU core instructions were never a bottleneck, but I did want to fix the P flag building stuff because that really was a dumb mistake v_v'
