Turbo Double Dragon + Star Strider
Run the updater or copy the files from JTBIN
Double Dragon is famous for its slowdowns. And they are not by design. The developers have said in interviews that they did not have the resources to prevent the slowdowns. So ever since I published the FPGA core for these games, I have been asked to speed up the gameplay.
I finally got it working in a stable way this week. The results are shocking: it feels like a completely different game. Whereas before, the slowdown was noticeable since the first enemy appeared on screen; now, you need to get as many as five of them to start noticing something.
This may be the one time where I prefer to alter the game hardware. However, this is completely optional: use the turbo option in the menu to enable and disable it.
This also applies to Double Dragon 2, although that game did not suffer as much as the first one.
This week, I have spent time getting the star fields in CPS1 games to match the original hardware. Loic recently finished his research on the CPS-A chip, and I wanted to compare it with the JTCPS implementation. We all knew the starfields were wrong in the core and emulation. No one knew how they worked, so Loic's research was vital. Finally, today, we have the real starfield for Strider! Check out the pictures of a PCB vs the JTCPS core. Getting this fine level of detail right is a dream come true!
And MX5000 is promoted to public core, as no issues were reported in a month as beta, so I think it's good to go. Thank you so much to all of you for supporting this development.
I am preparing something big for October, so stay tuned!

Double Dragon es famoso por sus ralentizaciones. Y no lo son por diseño. Los desarrolladores han dicho en entrevistas que no tenían los recursos para evitar las ralentizaciones. Desde que publiqué el núcleo FPGA para estos juegos, se me ha pedido que acelere el juego.
Finalmente logré que funcionara de manera estable esta semana. Los resultados son impactantes: parece un juego completamente diferente. Mientras que antes, la ralentización se notaba desde que aparecía el primer enemigo en la pantalla; ahora, hasta cinco de ellos tienen que salir para comenzar a notar algo.
Este puede ser el único caso en el que prefiero alterar el hardware del juego. Sin embargo, esto es completamente opcional: usa la opción turbo en el menú para habilitarlo y deshabilitarlo.
Esto también se aplica a Double Dragon 2, aunque ese juego no sufrió tanto de parones como el primero.
Esta semana, he pasado tiempo haciendo que los campos de estrellas en los juegos de CPS1 coincidan con el hardware original. Loic terminó recientemente su investigación sobre el chip CPS-A y quería compararlo con la implementación de JTCPS. Todos sabíamos que los campos de estrellas estaban mal en el cor y en emulación. Nadie sabía cómo funcionaban, por lo que la investigación de Loic era vital. ¡Finalmente, hoy, tenemos el verdadero campo de estrellas para Strider! Compara las imágenes de una PCB frente al núcleo JTCPS. ¡Conseguir este fino nivel de detalle es un sueño hecho realidad!
Y MX5000 pasa a cor público, ya que no se informaron problemas en un mes como beta, así que creo que está listo. Muchas gracias a todos ustedes por apoyar este desarrollo.
Estoy preparando algo grande para octubre, ¡así que estad atentos!

I was going to play Double Dragon today and I notice that the core is now missing the “Turbo” option. It was such a great feature. Any chance that for it to be included again in the core options?
ok very cool!
Hello, what's about the star field in forgotten worlds?
You’re right. It’s in the to-do list.
And it now works. I'm such a noob in the mister universe. Always update your core files! Thanks for taking time to dig this problem, which wasn't since it's the user's fault (me). Keep up the good work. Gracias.
Well I tried all you the solutions you kindly answered guys. Put the jbeta (zipped and unzipped) available with Ninja vs bad dudes. It works for this game, but nothing new for all the S16 games. Such a shame that this protection has been put. Though I totally understand why. Will wait for the S16 games to go public in order to play them. .. Don't understand why people leaking it from here are not advising their friends to back Jose. 3 € a month or so is nothing comparing to the work involved form him. Human Nature I suppose.
I'm sorry you're troubled. The closed betas help finance the development; I know you understand. Thank you. Your problem is that the S16 files you have are old. If you just unzip the latest published MiSTer file (found in Discord or the last Patreon post) it will get all files for all beta cores in the right place, including the jtbeta.zip If you have moved the MRA and RBF files to a different location, those files won't get updated. I think that must be the problem.
¿Lo de las estrellas de Strider también está disponible en MiST?
Si
Thank you for what goûte doing. My Egret 2 loves your mister work. I can’t run the s16 games without having the jotego bêta screen permanently staying. I put tg jbeta. Zip in the mame folder, but it dies nothing. What am I missing?
Hi, just unzip the MiSTer zip file directly on your SD card and that will get all the files in the right place. If your system has more than one MAME folder, MiSTer may fail to load the files.
Love this update. Feels like a new game!
Thanks! Nice to see that this is also available for Mist FPGA! :D
Just uploaded a 1cc Double Dragon playthrough on my YT channel. https://www.youtube.com/watch?v=ILesLi_GZ_Y
i watched your playthrough. lots of fun :-)
Turbo make the game great again
Turbo and quality hacks like final fight 30th anniversary, it’s like an arcade renaissance :)
such nice little improvements to receive. i love the attention you pay to all the cores you work on. keep the great work up :-)
Great stuff as allways thankyou . Im a patreon for the year but now and then i get locked out like i have been this weekend ? Any ideas?
CPS1 DIP settings are not accessible in 20211001
Excited for whatever you're cooking up for October because you never disappoint! More power!
Looks like an update for Double Dragon was made available. I did an update again and now Double Dragon is working over HDMI with audio. @Jotego - Thank you very much for the release and the fix.
I lost hope that I was ever going to play Double Dragon without slowdown. If the update works out I will upload a 1cc playthrough with commentary to my channel next week. I'm really looking forward to this. Thanks Mr. Tejada!
I was looking forward to working on a Cotton arcade 1cc tonight but now it looks like I have to play Double Dragon instead. First world problems.
José, toda una hazaña conseguir que los slowdowns del clásico entre los clásicos ;) de los juegos de lucha, el todo poderoso Double Dragon, dejen de ser un problema y que su jugabilidad ahora vaya más allá de lo que ya en su día consiguió la PCB original. Una gozada. Muchas gracias y a disfrutarlo todos
Hora de probar los nuevos juguetes. Muchas gracias como siempre Jotego.
We only needed to update ? Because I see nothing with updater ?
fantastic work 🤪👍
Gracias. Strider es de mis arcadles favoritos. El mimo y la obsesión por el detalle….!!!!
Strider looked good, thanks JT. Did forgotten worlds get affected? Stars seemed odd in that. The about string in the menu seemed odd as well… I also couldn’t see the options in 1942 for changing the orientation any more? And the aspect ratio options were not showing in CPS1 I think?
Thanks
Double Dragon has an invalid signal rate not compatible with TV or monitor, it’s something like 45/47 hz.
Please update again, sorry about that.
Im not getting any sound on double dragon over hdmi or optical audio. double dragon 2's sound is working fine.
Please update again, sorry about that.
Thanks Jotego! Yes, i can confirm @Arrrrrrrgh post. same problem on my LG Oled B9.
Double dragon seems broken. I get no signal from the core on a LG Oled
I am getting the same thing. I am getting an analog RGB signal on my CRT, but not over HDMI, and I am not hearing any audio out of the optical audio out. If I switch to a different core, then everything works as normal.
Love this update, circling back and improving what’s already released is
You're doing great!
Love improvements to the CPS1 core. Looking forward to what’s coming in October.
Very well done! Better than the original...exciting! > I am preparing something big for October, so stay tuned! Uh, oh, I hated this when my mother said something like that :) But once my father said that in 1981, an Atari 400 appeared in the living room! Personally I'm dreaming of "I, Robot", "Outrun" or "Cruising USA" *sigh*
Brilliant!
Mucha gracias! sobre: MX5000 hay algun cambio o el updater se encarga de todo?
El updater se encarga
