Street Fighter II

(español abajo)

What you need to know:

-New MRAs. Delete old ones so buttons get recognized properly.
-I have only tested the main ROM MRA versions. I know many of the alternative versions will fail. Please report them here.
-Files are in the location indicated in the first CPS beta post.

I have spent most of the week verifying the core timing. I think the 10MHz games should be running at the exact speed now. The DMA has been implemented as explained here and this has definetely changed the play feeling for some games. About 12MHz games: I cannot be sure on accuracy as I don't have any 12MHz board. It is commonly said that only the clock changes in this board but I wonder if the memory wait states were changed too. There are a couple of minor questions still open for DMA but current implementation does comply with all measurements I have made so far. Be sure that the next best thing to the original PCB is this work you are sponsoring.

I know some people made MRA for SF games. I would like to avoid confusion about them. If you are going to record a video of the core, please use this RBF with these MRAs. This is the only one that will produce accurate timing. I left SF2 for last because I wanted to show it with accurate timing.

Oh, SF alpha/zero is also included this week. This is a home version for the CPS charger console.

Forgotten worlds will take one more week. It was the first game published for CPS by CAPCOM but it is going to be our last! I just didn't have time to finish it.

Enjoy Street Fighter 2 and thank you for support!

-Los MRA son todos nuevos. Borrad los antiguos
-Sólo he probado los MRA de las versiones principales. Si las alternativas dan problemas por favor dad parte aquí.
-Los ficheros estan donde decia la primera entrada sobre CPS.

Me he pasado la mayoría de la semana midiendo y ajustando los tiempos del cor para que sea clavado al original. He cambiado la arquitectura de vídeo para que replique los tiempos de bus originales. Ha sido bastante intenso. Os aseguro que este trabajo que patrocináis es el que os ofrece la mejor versión de CPS después de la placa original.

Sé que ha habido gente que ha distribuido MRAs para SF. Sólo os pido que si grabáis un vídeo, uséis los MRA y el RBF que os entrego esta semana. Sólo este RBF va a dar los tiempos exactos del juego. He querido dejar SF2 para el final para asegurarme de que se viera la potencia de la FPGA clavando los tiempos.

Por cierto, SF alpha/zero también se incluye esta semana. Forgotten Worlds tendrá que esperar porque no he podido terminar los controles aun.

¡Disfrutadlos y gracias por vuestro apoyo!
