I went back in this thread to get Cyberlip so I could get that DNCD VMU save file. But Cyberlip says it is v2.9. Will it still have the DNCD sav file I need for your DN3.0 games?

Yes :) can also use windjammers lose a match let the timer count down run out then it ask to save data then the save file is there..Do the first level of cyber lip, died, did the save, now working without issue..

Converted all scaling from integer math to sh4 floating point math for scaling and tile creation. The Sh4 CPU is very slow at integer math and division. 

Fullspeed now.

Coming soon
Metal slug 1 best it can get :)

  • This game suffers from tons of slowdowns on the real NeoGeo CD machine and AES. I have used Dreamcast hardware to minimize delays between frames. It will still be slow in the same places, as this is built into the code of the engine. However, one thing that you can spot is that in the 68k assembly, there is a 30 fps lock code that is causing extra frames to be dropped. If the game was missing one frame, it would miss two. If it missed three, it would instead miss four. A game with a built-in frameskip in the game's code, which I can't change. I have micro-optimized frame pacing in the rendering to try to counter this; the actual delay between frames is reduced by 2 across all speeds. To improve things more would mean actually rewriting chunks of 68k assembly code, as apparently there are many slow functions in there. And no one is going to do this. So this is one of the best-running versions, better than on a real machine or arcade. So for the emulation on Dreamcast, we have better than real hardware. I can't take away all of the slowdown and skip frames, as this is in the 68k assembly of the actual game code.Not in the emulation of the game on Dreamcast.
Crazy metal slug2 shares the same code but worst..
