We worked on Parodius da! schematics last year. It turned out to be very similar to The Simpsons board, with some differences:

Different sprite chipset: 053244/5 instead of 053246/7. This chipset  is very similar but only supports half the sprite count of the Simpsons one. Sprite scaling uses a different range and there are some small  changes in what configuration bits mean that brought a bigger headache  than expected...

Sprite shading disabled (devices not soldered on the board)

Differences in device memory mapping

I have extended JTSIMSON to support this  board. The game seems fully playable although I have only tested the  first two levels. You will notice some broken sprites due to the sprite  scale range not being fully implemented yet.

This game also uses an unknown CPU instruction. This is  the Konami CPU for which not everything is known yet. We are kind of  bypassing that instruction and the game seems to run ok. We want to  experiment with the original hardware to derive the instruction meaning  and correctly implement it.

Other fixes

Bubble Bobble music too loud

NeoGeo Pocket flash writes. This enables games such as Puzzle Bobble to operate correctly

Experimental DV1 support. Users, MiSTer developers and Mike Chi helped to identify a problem in the MiSTer files used in JTCORES. This update may fix the problems when connecting a RetroTINK 4k device

El año pasado trabajamos en los esquemas de Parodius da!. Resultó ser muy similar a la placa de The Simpsons, con algunas diferencias:

Diferente chipset de sprites: 053244/5 en lugar de 053246/7. Este chipset es muy similar pero sólo soporta la mitad de sprites que el de The Simpsons.  El escalado de sprites usa un rango diferente y hay algunos pequeños  cambios en lo que significan los bits de configuración que dieron algo  de quebradero de cabeza...

Sombreado de sprites desactivado (dispositivos no soldados en la placa)

Diferencias en el mapeo de memoria de los dispositivos

He extendido JTSIMSON para soportar esta  placa. El juego parece totalmente jugable aunque sólo he probado los dos  primeros niveles. Notarás algunos sprites rotos debido a que la escala  de sprites no está completamente implementada.

Este juego también utiliza una instrucción de CPU  desconocida. Se trata de la CPU de Konami de la que aún no se sabe todo.  Estamos pasando por alto esa instrucción y el juego parece funcionar  bien. Queremos experimentar con el hardware original para deducir el  significado de la instrucción e implementarla correctamente.

Otras correcciones

Música de Bubble Bobble demasiado alta

NeoGeo Pocket flash escribe. Esto permite que juegos como Puzzle Bobble funcionen correctamente.

Soporte experimental para DV1.  Usuarios, desarrolladores de MiSTer y Mike Chi ayudaron a identificar  un problema en los archivos MiSTer utilizados en JTCORES. Esta  actualización puede solucionar los problemas al conectar un dispositivo RetroTINK 4k

Una sugerencia 🙂, ¿podrías poner un changelog en Github? Es más porque lleva a confusión ver todos los cores de MiST y Sidi actualizados pero no saber qué cambios se han hecho o si son iguales, sobre todo cuando toca actualizar. ¡Muchas gracias! 🙂

ronalvel .

Excelente trabajo! Gracias

JOTEGO

Básicamente cambia lo que he puesto aquí. Pero recompilo todos los cores para que todos estén en la misma versión. En el caso de la MiSTer, todos han adquirido la salida DV1 de Retro Tink y por tanto todos han cambiado. Para SiDi o Pocket, la mayoría serán como la semana pasada.

Fabuloso trabajo! mil gracias a ti y a tu equipo, Jose

Jeruro

Un arcade muy esperado. Mil gracias!!

I had forgotten about Jotego Friday. A wonderful surprise to wake up to today! Thank you as always!

birdybro

Thank you, this is one of my favorite game series in the arcades so I'm very excited to try it out!

Big Al.

)ne of the best Jotego Fridays. Thankyou

Mat Azel

Parodius Da! in beta and retrotink 4k support being worked on makes me so happy! thank you so much^^

Anthony Monaco

I was excited to try the Parodius core, but I cannot get the controls to work at all. I'm on MiSTer and got the core from the update_all script. I tried remapping controls multiple times with 2 different USB game pads, but no luck. I tested the Simpsons core as well and controls don't work there for me anymore either. But controls still work fine for me with other cores. Is this happening for anyone else?

JOTEGO

Try deleting old config files for jtsimson in the config folder. I assume you do not have problems with the beta key.

JOTEGO

Thank you for your help in fixing the RetroTink support

Anthony Monaco

I deleted config files but it didn't seem to work, so I went and deleted all files related to the Simpsons or Parodius from my SD card, deleted and reinstalled the beta key, and then ran update_all again and that fixed it! Thanks for the help

Mat Azel

I've been getting an invalid beta key error for some time with jtbubl with pocket updater 1.60, I did delete both asset and core, betakey on the root and everything. No issues on mister. ParodiusDA and simpsons stopped working on the pocket (bad rom being pulled for now maybe)

Mat Azel

Thank you, I had the same issue, it worked ^^

Daniel Thomas Stack

Great to see this game playable. Looking forward to improved chip support when you get that signal worked out.

AlxUnderBase

Nice release , Jose ! Thank you !

Anthony Monaco

With the help of rapid fire and a few hundred virtual quarters, I can confirm the game works at least up to level 8. That's when I hit the wrong button on a game over screen and was sent back to the title screen lol. Great work as usual Jotego!

Luke Barton

I get the splash screen but credits are rolling and can't do anything.

Luke Barton

actually have credits on all the cores now

Josh Parker

I've been having the same problem with those cores too.

Josh Parker

I have been having problems with The Simpsons, Splatter House, and Bubble Bobble cores are all getting black screens after they load. I tried deleting them all and trying again, but it was still the same thing. Then I tried it on a completely new SD card, and it still did the same thing. Does anyone know a solution?

Owlnonymous

Very cool. Thanks for another fantastic shmup.

2026-09-06 20:00 I can’t get ANY game to load on the Neo Geo Pocket core. No matter what game I try to load, it goes right into the Pocket menu. Try to load a cartridge from the menu while on this screen and it won’t even do it.

JOTEGO

You need to turn off and on the NeoGeo Pocket itself after loading a cartridge. There is one button in the core assigned to do that, which would normally be the 1P button in arcades. When you turn it off, the screen goes white, then turn it on again and it should boot to the game.

JOTEGO

Use the search in your file manager to delete all beta.bin files from the Pocket SD card, and then unzip the attached zip at the bottom, the one for the Pocket. That zip will place beta.bin at the right place for you (which is Assets/jtpatreon/common/beta.bin)

JOTEGO

Thanks! That's good to hear

A black screen in MiSTer usually means missing ROM files

2026-09-06 20:00 Okay, so doing testing on the NGPC backwards compatible titles and tried where I press select to “power off” the core and then I load the next cartridge. Doing this, it’s pretty much loaded everything I threw at it so far and I’m going down the Wikipedia list and I’m at Dark Arms right now. So it appears for now that if you want to load games, DO NOT USE THE MENU WITHOUT PRESSING SELECT FIRST….wait for the white screen to appear THEN go into the menu to load the game. It will then load automatically and hopefully not go back to the pocket menu

ok, I did not know about asset/jtpatreon, but I'm 100% sur jtbobble has the latest key in the right place, it's been like this for a few update for me, will report back

mpatou

Great news having Parodius DA working! By the way, I guess Analogue has still not given us the possibility to remap controls for player two when docked? By the way, one more thing I would like to report about Parodius DA : scaler effects can be glitchy (like title screen in The Simpsons). I noticed that with the big explosion when you get the blue bell then press BOMB button. I took a screenshot if needed.

Mat Azel

deleting the keys made the gui updater crazy, telling me jt1942, jthouse, jtsimson, jtbobble etc had an invalid key (it was on the root and jtpatreon) did copy it manually and all cores worked but jtsimson. so it was probably a bad rom... as usual I switch the the command line updater, and yeah I had a loooooooot of bad rom/checksum apparently (yes, crc is on in the gui updater) anyways, Parodius da! and the simpsons work perfect now!

JOTEGO

Exactly. It is a bit of a pain but in the real console you would turn it off before pulling off a cartridge. Maybe I'll find some way of turning it off for the user in the future.

Salvador Perugorria Lorente

Iba a probar Parodious Da!, ¿no está la nueva versión de JTSIMSON para MiST o Sidi? Saludos :)

Intron Official

That would be a nice firmware feature from Analogue to implement; Portable Control mappings and Docked Control mappings independent of each other. Not sure if it's possible, but would be a nice to have.

JOTEGO

Thank you. The sprite scaler in Parodius is not fully implemented yet.

Josh Parker

its the Pocket and I seem to have the ROMS in the commons file

Fred Clever

Thank you for doing Parodius da! on Mister, one of my most loved arcade games. Now tho only arcade I'm missing on Mister is 'Sunset Riders'....

Gabriel Pyron

Master Jotego, Av you help me with one information? Can you tell me what is the correct cpu and clock thats Parodius uses? I do not find the correct info on the Internet, thank you in advance
