Hello BizHawk devs. Some cores are much slow compared with previous versions and just run in good speed if using CPU Power Profile High Performance using much more energy. NESHawk and A7800Hawk are much slow. I not has information if is because accurate code. If yes in future has chance of code to be optmized or added an option to select previous cores for both system NES and Atari 7800 ? Thanks for read my post.

For NES, you have the QuickNES option (Config -> Cores -> NES) its much faster. For A7800, nope EMU7800 is gone for good. Occasionally I try to make the code faster, but with limited success, but maybe in the future.

Thanks very much Alyosha for reply. QuickNES is fast, but not start several games. QuickNES is more accurate than Nestopia ? "For A7800, nope EMU7800 is gone for good." The slowdown is accurate. Right. Currently N64 core is crashing when starting any game. 32X core has sound channels extremely much high than others channels. 32X core is good, but the sound channels not are balanced. Try start MK2 the voices are extremely much high and the music is low being wrong. I has posted about it in anothers topics being a problem in emulation, but not has reply. Thanks for reply and good luck in you path.

Are you using GDI+ Rendering? Go to Config, Display, Display Method. OpenGL or Direct3D9 is recommended, if you can't select those, your PC/Laptop has a bad graphics card.
When TAS does Quake 1, SDA will declare war. The Prince doth arrive he doth please.

I believe Nestopia is more accurate at least for it's most recent releases. Yeah QuickNES has low compatibility but that's not really it's goal. A7800Hawk is much more accurate yes. But it's also slower just because it's in C# and I haven't really optimized it at all since finishing it.
