2023-11-17 Gang Busters and Public Releases

The JTALIENS core receives support for a new game added this week: Konami's Gang Busters.  This is a cute two-player game that reminds of Labyrinth Runner and  CAPCOM's Avengers. The cop duo of the diminutive Smith and the taller  Wesson (over the pistols Smith & Wesson), who can't help but shoot  when they have a gun, shoot, shoot, shoot to protect their town from  bank robbers RED GANG! This is Konami's signature character shooter  game. It is one of those hidden games that not many people know. Check  it out!

Cores promoted to public

The Final Round arcade core has been renamed to JTFROUND as it is clear now that it will not work easily on the same core as  Konami's Twin16 titles. As this core will not see more titles added, it  is promoted to public. It still has a minor graphical glitch at the end  scene, but I will tackle it on the JTTWIN16 core, which shares that part of the logic.

As part of the consolidation work done on cores, the games Tiger Road and F1 Dream work now on the same core: JTTORA. 1942, Pirate Ship Higemaru and Vulgus operate now off the JT1942. And all Super Basketball game versions work on the same JTSBASKT core. This change is transparent to MiSTer users, but Pocket users get support for F1 Dream with this week's update as a side effect.

JTS16, supporting SEGA System 16A games, which was a beta for the Pocket, is now public. JTNINJA, supporting Dragon Ninja and Heavy Barrel is also promoted to public.

Information about cores in beta phase can be found here

Core maintenance

ROM names changed

Because some games had name clashes in the ROM files, the  8-character limit in the .rom file name has been removed. This means  that the .rom files now matched the MAME set names but it also implies  that you are likely to rename (or regenerate) your .rom files. This  affects all platforms except MiSTer, which uses MRA files instead of .rom files.

Easier beta key handling

Pocket files for beta cores include a checksum  for the beta key file now. This will allow updaters to warn the user  when the wrong beta file is used. This should ease the setup process.

MiSTer MRA files also include it, but the MiSTer firmware will not warn you if the CRC is not met so it does not help much.

Español

El núcleo JTALIENS recibe soporte para un nuevo juego esta semana: Gang Busters de Konami. Se trata de un simpático juego para dos jugadores que  recuerda a Labyrinth Runner y a Avengers (CAPCOM). El dúo de policías  formado por el diminuto Smith y el más alto Wesson (referencia a las  pistolas Smith & Wesson), que no pueden evitar disparar cuando  tienen un arma, disparan, disparan, disparan para proteger su ciudad de  los ladrones de bancos ¡La banda GANG ROJA! Este es un juego de disparos  con personajes característicos de Konami. Es uno de esos juegos ocultos  que no mucha gente conoce. ¡Pruébalo!

Núcleos liberados

El núcleo arcade The Final Round ha sido renombrado a JTFROUND,  ya que ahora está claro que no funcionará fácilmente en el mismo núcleo  que los títulos Twin16 de Konami. Como este núcleo no verá más títulos  añadidos, se promociona a público. Todavía tiene un pequeño fallo gráfico en la escena final, pero lo solucionaré en el núcleo JTTWIN16, que comparte esa parte de la lógica.

Como parte del trabajo de consolidación realizado en los núcleos, los juegos Tiger Road y F1 Dream funcionan ahora en el mismo núcleo: JTTORA. 1942, Pirate Ship Higemaru y Vulgus funcionan ahora todos en JT1942. Y todas las versiones del juego Super Basketball funcionan con el mismo núcleo JTSBASKT. Este cambio es transparente para los usuarios de MiSTer, pero los usuarios de Pocket obtienen soporte para F1 Dream con la actualización de esta semana como efecto secundario.

JTS16, compatible con los juegos de SEGA System 16A, que era una beta para Pocket, ahora es público. JTNINJA, compatible con Dragon Ninja y Heavy Barrel, también se ha hecho público.

La información sobre los núcleos en fase beta puede encontrarse aquí

Mantenimiento de núcleos

Nombres de ROM cambiados

Debido a que algunos juegos tenían conflictos de nombres  en los archivos ROM, se ha eliminado el límite de 8 caracteres en el  nombre del archivo .rom. Esto significa que los archivos .rom ahora  coinciden con los nombres de los juegos de MAME, pero también implica  que es probable que tengas que renombrar (o regenerar) tus archivos  .rom. Esto afecta a todas las plataformas excepto MiSTer, que utiliza  archivos MRA en lugar de archivos .rom.

Manejo más sencillo de las claves beta.

Los archivos Pocket para núcleos beta incluyen  ahora una suma de comprobación para el archivo de clave beta. Esto  permitirá a los actualizadores avisar al usuario cuando se utilice un  archivo beta incorrecto. Esto debería facilitar el proceso de  configuración.

Los archivos MRA de MiSTer también lo incluyen, pero el  firmware de MiSTer no te avisará si no se cumple el CRC, así que no  ayuda mucho.

When odd things like that have happened to me, I have just turned the device off, eject and re-insert the SD card and power on again. SD cards are not the most reliable device and it sometimes does not get inserted correctly.

JOTEGO

Anybody loaded up open FPGA and when trying to select anything from the menu the screen goes back to the previous screen? Like you can't go into any of the selections for any of the cores.

Robert

Even if Final Round includes beta.bin, it does not work properly.

엘케

This worked. Thank you.

jimmysombrero

All working but Simpson’s upside down argh any ideas

Wayne

JT1942 ¿Va a actualizarse en MiST y en Sidi? Los MRA nuevos ya no funcionan con los actuales cores. ¡Gracias!

Salvador Perugorria Lorente

Thanks ,Jeremiah. That would be my suggestion too.

JOTEGO

Not yet

JOTEGO

Try deleting all the files iin this folder: on the sd card: Saves>jtsimson>common

Jeremiah Finn

That would be so awesome I’m hoping the same thing..

THE_MAQ

The simpsons title zoom in during the intro problem I mentioned a few weeks ago have you looked into it yet?

THE_MAQ

Love all great work and releases so far, was wondering if the Sega Y Board and or Sega System 32 are on the horizon?

Icehawk

Got it working, when in doubt just do a clean reinstallation!

Notaturnip

I assume you are using MiSTer. The right folder to copy jtbeta.zip to is /games/mame Make sure you only have one mame folder as MiSTer may only look for the jtbeta.zip in one of them, or you may have an old copy in one of the folders

JOTEGO

I have thought of it, but I want to get a bit of own backlog released first. Please remind me again next year if you don't see progress from Blackwine

JOTEGO

Thanks, already tried that but no luck.

Notaturnip

Would it be possible to continue the work Blackwine did on Sega System 1? Specifically Wonderboy in Monsterland. It seems it's working but looks like he stopped FPGA work altogether.

Steven Kirkham

Check out this FAQ https://github.com/jotego/jtbin/wiki/Why-I-only-see-the-on-screen-credits%3F

JOTEGO

Have the beta key installed at /mame and have a core credits loop on Simps and TMNT, any ideas to fix this?

Notaturnip

Holiday gifts for all, thank you!

ER

Same for me as well. It's upside down and the bootloop issue is still present.

jimmysombrero

Hello Jotego, thank you for the suggestion! The MD5Sums matched perfectly. The solution was to delete the jotego.jtaliens inside the settings folder.

Jan S.

same. and I still can't get 2 player to work

Nick C

Simpsons is upside down after the update :(

Alex Quiroz

Hi thankyou for testing, providing that you are also on Mister unstable? this is very strange, I'll go ask in the MisterFPGA forum..thanks again!

Lee Turner

Pram0d is still working on Mortal Kombat.

JOTEGO

I would say that the ROM files are not correct. If you don't mind tinkering, you can check the MD5 sum of the files generated. It is written in the MRA files (look for asm_md5). That should match the one your .rom file produces.

JOTEGO

Good stuff keep it coming!

Shannon Thomasson

works ok here.

Big Al.

Pocket: After finally play gang busters and crime fighters they load, but simply are not playable, screen is garbled on crime fighters and gang busters shows not much besides the game logo with some black bars. Aliens and Contra work fine tho. Is this maybe a "merging error" on my side? Took the MRAs from the JTBIN and the rest from the latest Pocket.zip Any ideas anyone?

Jan S.

@JOTEGO, what would it take to have a turbo as a granular option on the Pocket? I know some ppl are against it...that being said, no one is forcing it on them on mister, and I see it more as an accessibility feature especially for 80s arcade hardware. Can only Analogue do something? if so, it feels like only devs like you could reach out to them about it. as usual, thank you👍

Mat Azel

Amazing! Any progress on Midway's arcade boards?

Amy Veeres

I hope it's ok to ask here as this game is not Jotego's core.. Is Wonderboy arcade still working for anybody? I'm on the latest Mister unstable, and I've deleted and redownloaded the MRA and game ROM.zip and upon loading, the game stays on a black screen not crashed, GUI still accessible, thanks.

Lee Turner

Gracias por seguir con vuestro genial trabajo y seguir dando apoyo a MiST y Sidi 🙂

Salvador Perugorria Lorente

exactly what I was going to do... thanks for the tip and the great work

Thierry SAINT-DENIS

Use a new SD card on your Pocket for this, as you may end up corrupting files in your regular SD installation. It may be the best to give a few days to the maintainers of the update tools to catch up.

JOTEGO

Thank you so much for the updates, you and your team rock Jotego!

Matthew Belshan

Cheers to all your work team JT, happy Friday

Mark Saunders

Really cool updates for ease of access too! Hopefully this helps stop a lot of the questions :)

tom

What a huge QOL update! This is what dedication looks like, both to your craft and to the patrons.

Dan Avedikian

TheHellblaz3r

Wow! The value for subscribing to this Patreon is through the roof! Thanks JT and team!

Richard Maxey

thanks a lot for the update, Jose !

Mat Azel

I have not touched it in the last month. But I will get back to it.

JOTEGO

Thanks as always for the update !

Benouz

Thanks as always, have a great weekend!

Bedwablackburn

Thanks for the update JT. What’s going on with Neo Geo Pocket? Haven’t heard anything in quite some time.

James Kilgore

Many thanks team. Have a great weekend 😄
