We visit this week a hardware from Data East that preceds Robocop and Dragon Ninja. The board is similar to those games in the main CPU, the sound subsystem and some of the glue logic but the graphics subsystem is more primitive.

It uses three layers: characters, scroll and sprites. The characters can have 8 colors per pixel whereas the scroll and sprites can have 16. This made the SEGA Megadrive version more visually apealing as it had a second scroll layer.

The game mechanics make this gun & run remember a shooter as the scroll is forced upon you and you cannot stop to take a breath.

The beta implementation has a problem with some characters that you may spot in the score. I think that the rest of the system is working correctly.

The game PCB was donated by Atrac17 and DJ Hardrich but, as it often happens, it didn’t work when we plugged it. It’s very sad how easily this old hardware breaks. We investigated it a bit and found a possible culprit but we haven’t repaired it yet. So the core is based on the official board schematics. Those are clear enough to have good confidence.

I know that many of you are getting your Pocket devices about this time. I am sorry but Chelnov isn’t ready for the Pocket this week. Nonetheless,  attached to this post is my JTCPS1 core for the Pocket, compatible with games such as Street Fighter 2, Final Fight or Ghouls’n Ghosts, among many others. Enjoy!

Merry Christmas

Visitamos esta semana un hardware de Data East que precede a Robocop y Dragon Ninja. La placa es similar a la de esos juegos en la CPU principal, el subsistema de sonido y parte de la lógica general, pero el subsistema gráfico es más primitivo.

Utiliza tres capas: personajes, scroll y sprites. Los personajes pueden tener 8 colores por píxel, mientras que el scroll y los sprites pueden tener 16. Esto hizo que la versión de SEGA Megadrive fuera más atractiva visualmente, ya que tenía una segunda capa de scroll.

La mecánica del juego hace que este gun & run recuerde a un juego de naves, ya que el scroll se te impone y no puedes parar ni para respirar.

La implementación beta tiene un problema con algunos caracteres, como verás en la fila de marcadores. Creo que el resto del sistema está funcionando correctamente.

La PCB del juego fue donada por Atrac17 y DJ Hardrich pero, como sucede a menudo, no funcionó cuando la enchufamos. Es muy triste la facilidad con la que se rompe este viejo hardware. Lo investigamos un poco y encontramos una posible causa, pero aún no lo hemos reparado. Así que, el cor se basa en los esquemas oficiales de la placa. Esos son lo suficientemente claros para tener confianza en el resultado.

Sé que muchos estáis recibiendo vuestras Pocket estos días. Lo siento pero Chelnov no está listo aun para la Pocket. Sin embargo, tenéis en este post mi cor JTCPS1 para la Pocket, compatible con juegos como Street Fighter 2, Final Fight o Ghouls’n Ghosts, entre muchos otros. ¡Disfrutadlo!

Feliz navidad

チェルノブ(ベータ版)、ポケット版CPS1今週はデータイースト社のロボコップやドラゴンニンジャよりも前のハードについてです。この基板は、メインCPU、サウンドサブシステム、一部のグルーロジックはそれらのゲームと似ていますが、グラフィックサブシステムはより原始的なものです。

キャラクター、スクロール、スプライトの3つのレイヤーを使用しています。キャラクターは1ピクセルあたり8色なのに対し、スクロールとスプライトは16色もあります。このため、SEGAメガドライブ版では、2つ目のスクロールレイヤーがあり、視覚的により魅力的でした。

ゲームメカニックは、スクロールが強制され、一息つく間もないため、このガン&ランはシューティングゲームを思い出させます。

ベータ版の実装では、一部のキャラクターがスコアで見切れるという問題があります。それ以外は正常に動作していると思います。

ゲームPCBは、Atrac17とDJ Hardrichから寄贈されたものですが、よくあることですが、接続しても動きませんでした。この古いハードウェアが簡単に壊れてしまうのは、とても悲しいことです。少し調査して、原因らしきものを見つけましたが、まだ修理はしていません。そのため、コアは公式のボード回路図に基づいています。それらは十分にクリアで、信頼性があります。

ここ最近、Pocket端末を入手される方も多いと思います。申し訳ないのですが、チェルノブは今週Pocket版の準備ができていないのです。それでも、この投稿には、ストリートファイター2、ファイナルファイト、大魔界村などのゲームに対応した、私のポケット用JTCPS1コアが添付されています。お楽しみに!

メリークリスマス

CPS1 for the pocket is a very nice Christmas gift!

Antonio Negro

Can't wait to go back home and make this work on my Analogue. Thanks

Mat Azel

hehe, that's awesome thank you for the xmas gift for the Pocket ! (it work a treat :) ) I was wondering, any chance you can somehow add "autofire" to your Pocket framework ? I guess this should be an analogue system-wide thing, but since they aren't adding anything much like this themselves lately (or filters, or DAC support, sigh) I though maybe you have a take on this or pass the ask along (since we can't communicate with them) this is needed especially for early arcade shmups for instance.

Mat Azel

can also confirm there's no sound while docked ^^''

Bob Zindle

Thanks Jose and team. Merry Christmas!!!

Mat Azel

Guys PocketSync is really good and getting CPS1 up and running. If you need any assistance, there is a video tutorial on my YouTube channel. I'm having a blast playing them on the AP.

thank you for your hard work
