Double Dragon Public Release MiST(er) and SiDi
(español abajo)
If you have to spend more time at home in the next few days, as some of us, then at least kick some ass! After a long wait, here it is Double Dragon! Finally open to the public. Files are in jtbin, just run the the update script in MiSTer to get them.
Sorry for the long wait. Initially DD1 was meant to be released in January but I got engaged with CPS and well, it kept me engaged! Now it's finally here. The release has been hard because for some reason Quartus (FPGA compiler) decided that the CPUs were not meeting timing now -they were ok in the beta- and I had to make some system level modifications in order to meet timing requirements consistently.
A similar problem is holding DD2 at the moment. I hope I can fix that one soon too and release it. The source code for both cores will be released with DD2.
EDIT: DD2 is available now too. You may need to reset it once for it work. There's a bug related to the CPU that I still haven't caught.
Enjoy!

Para los que estéis en España, tenemos por delante unos días en casa. Así que, además de aprovechar para quitar el polvo de encima de las puertas, podemos echar alguna partidita a un clasicazo: Double Dragon, que a partir de hoy está disponibles para todos en FPGA. Los ficheros están en jtbin. Si usas MiSTer puedes conseguirlos con el script de update para mis cores.
Lamento la larga espera. Iba a lanzar el DD1 al público en enero, pero me puse con CPS, y bueno... no podía dejarlo. Encima al preparar la versión pública Quartus (el compilador para FPGA) ha empezado a fallar en los tiempos y me ha tocado hacer cambios en el sistema para asegurarme de que los tiempos estaban correctos.
Un problema similar se interpone con el lanzamiento de DD2. Pero espero tenerlo listo pronto. El código fuente para DD1 y DD2 lo publicaré junto al DD2.
EDICION: Ya esta disponible el DD2 también. Puede que tengas que resetear después de la carga para que funcione bien. Hay un fallo en el Z80 que aún no he conseguido cazar.
¡A gozar!

how can I download the cores? please can you just put it on a shared directory? its complicated running those odd scripts
Hola José, están todos los binarios en https://GitHub/jotego/jtbin excepto los juegos en beta cuyos ZIP puedes encontrar en la publicación de Patreon que anuncia la beta. Gracias por unirte.
Both work like a charm for me. Audio, CRT. Look greats. Thanks pal.
Works for me without reset. Maybe it has to do with the RAM module, 128 MB RAM module here.
Cool :)
Clásico !!!! Gracias
very very nice !
Looks and sounds great, used to play this in my local arcade back in the day, a classic - thank you!
Looks Awesome JT! Plays great and image is perfectly centered ;)
Awesome! I'll have to celebrate by going for the 1CC again.
Thanks Jose! The game looks and plays perfectly and now analog video output works :D I found that the player 2, coin and pause/credits are swapped (coin pauses, player 2 inserts coin and pause is player 2).
Thank you for the report! I'll fix it
Sweet!
MRA files available in jtbin too. Batch file scripts for DOS also available.
Ive got a 128 MB Ram module. The 1st time I run DD2 it loads but just freezes when it starts the game, If I go in and reset it works fine...seems strange behaviour??
