Super Street Fighter 2 Support
(español abajo)
This week's update comes with a ton of internal changes. First, the SDRAM is now operated at bursts of 8 bytes, so graphics information is transferred in a single request. Together with other improvements, this change has boosted the number of sprites per line, and the X-Men COTA start screen is now correctly displayed.
I was misreading a part of the schematics related to bus timing. That is corrected too, so you may feel a speed up.
The start point for raster interrupts is now closer to the right value, and that renders Super Street Fighter 2 playable. To get this game working has taken quite some time, but it's finally here. So this week's core supports:
-Super Street Fighter 2 The New Challengers (32MB ok)
-Super Street Fighter 2 Turbo (32MB ok)
-Don't miss the hacked MRA files in the _other folder by Atrac17
Apart from CPS2, I have spent most of the week applying Furrtek's discoveries on the Konami chips to the Contra core. Contra, Combat School and Labyrinth Runner look much better now, including features that were not available in emulators. I will make a separate post for that when the files are ready.
Have a Super SF weekend!

La actualización de esta semana viene con un montón de cambios internos. Primero, la SDRAM ahora funciona en ráfagas de 8 bytes, por lo que la información gráfica se transfiere en una sola solicitud. Junto con otras mejoras, este cambio ha aumentado la cantidad de sprites por línea, y la pantalla de inicio de X-Men COTA ahora se muestra correctamente.
Estaba interpretando mal una parte de los esquemas relacionados con la sincronización del bus. Eso también está corregido, por lo que puede que notes una aceleración.
El punto de inicio de las interrupciones de ráster ahora está más cerca del valor correcto, y eso hace que Super Street Fighter 2 sea jugable. Hacer que este juego funcione ha llevado bastante tiempo, pero finalmente está aquí. Entonces, los soportes principales de esta semana:
-Super Street Fighter 2 The New Challengers (32MB ok)
-Super Street Fighter 2 Turbo (32MB ok)
-Nuevos MRA jaqueados de Atrac17
Aparte de CPS2, he pasado la mayor parte de la semana aplicando los descubrimientos de Furrtek en los chips de Konami al núcleo de Contra. Contra, Combat School y Labyrinth Runner se ven mucho mejor ahora, incluidas funciones que no estaban disponibles en los emuladores. Haré una publicación separada para eso cuando tenga los archivos listos.
¡Que tengas un fin de semana de Super SF!

Hello, someone pointed out to me (and I personally verified it to see if it was true or not, and they're right) that the core speed of various Super Street Fighter 2 and similar games cores is too high. To better understand what I mean, you can tell by watching the timer count down faster than it should, even with the clock speed set to 0 in the dip settings. So this person pointed out to me that in his opinion, the FPGA isn't as accurate as many people think. Is it possible to fix this problem in the various versions of SF2, SSF2, etc.? Thank you very much and best regards from Italy
Working great! And I like the mra file for New Legacy being included too - I've been meaning to check it out, and this was a great opportunity.
ST is the GOAT. Glad it's up and running on here. Nuked my arcade folder for the update, but 1944 LM and 19XX don't seem to start now. Everything else seems to work okay.
Thank you!!
The new memory controller has fixed the sprite problem I had in sfa2. Although it is a PSU related problem. I had connected the PSU directly to the 5V pin on the IO board. The decoupling on the de10 is not as effective then. I’m on to a new io board which will fix this and other things.
You think that you had a graphics issue because of the PSU, and now it is less sensitive to it. Is this what you meant?
Thanks Jose, your hard work makes Fridays even more welcome!
OMG! OMG! OMG!
lets go !
Excelente como siempre!!!a la espera de la correcion del Vampire Hunter 2!cuando puedas!muchos animos!
Hola Tony, ya está listo, bien en el adjunto a esta entrada o en el canal de betas de Discord. Siento el desliz.
I've been waiting for Super Street Figher for a while, it's good to know most of the issues have been fixed, looking forward for further improvements, thanks JT.
All of the ssf versions give me garbled graphics, all other games work flawlessly. Might do a fresh install first..
Me too
It is great that the Super Turbo core is out now, but strangely it doesn't work for me. I copied the files the same way as for the cps1 games (as described in the readme). Hyper Fighting still works fine, but ST just boots to a black screen. Anybody having the same problem?
Please check that you are using the latest RBF file.
🙏🏼
congratulations Jotego, I have been waiting for the perfect conversion for 27 years ... now your fame will increase because all the fans will take your version as a comparison for the arcade perfect;)
love jotego, been waiting for super street fighter 2 yessss! gracias!
I'd love someone make a MRA of the custom Rom of SSF2X Freeplay
I have the same problem with all vampire hunter 2 's Mra . And I have the same issue with XMen Vs Street fighter. All other games are OK
X-Men Vs. SF is working fine for me. You might try deleting your mame zip and redownloading it. Wouldn't hurt to re-copy the MRA over too.
Wonderful job, it was really an excitement to play these legendary games with the perfect arcade feeling! (by the way, I didn't remember how hard they were ;) ) thanks again!
Thank you for the awesome release Jose. It's truly great stuff. Where is the best place to post issues?
The Discord has a channel specifically for reporting issues.
Gonna be a great weekend. Cheers Jose! Cannot believe how quickly your getting these out.
Thank you for bringing back the most iconic games of my spoiled youth in the arcade!
Thanks for the hard work Jotego, we now have 🔥Super Street Fighter 2🔥. The Crown Jewel of CPS2.
Vampire Hunter 2 boots to a black screen after the update, I have tried a fresh delete/re-copy and running the update_all script again (I do this first before trying to boot anything) and this one doesn't run for me. Other games appear to be fine and I am running through all of them now to make sure
Same
SSF2 never looked, sounded, and played this good. Thanks for your wonderful work, Jotego!
Finally SSF. :) Thanks!
I love the way you keep drilling down and discover and fix problems. Keep up the awesome work. We love what you do Jotego :-)
Amazeballs! Is Capcom vs. SNK a possibility?
Those are Naomi games. Likely won't be possible on the Mister.
I guess you will round up the beta with a 💥 Giga Wing and Mars Matrix for dessert!
Could you add Super Turbo: New Legacy? Mod that runs on real hardware.
Okay didn't look through the files. Its already included!
Excellent, thanks as always looking forward to a session ;)
Thans will definetly try out these classics later!
Niice! - cheers and thanks! :)
Well done!
oh heck yeah!!!
This is a milestone release.
ok thats my weekend sorted
What a day!
You are Super Star ⭐️⭐️⭐️ Jose! Absolutely incredible work!
Have a great weekend. Make sure to take a rest.
Incredible! Amazing work as always, I had zero doubt that you would get these working.
Awesome!! Thanks Jose!
Gracias José, feliz fin de semana!
OMFG. New pants please.
