Nah, Tekken 7 would be better!

This game is fun, played it quite a few times on Mame.

How was the Map generation scene at the start of each level stored?

Looking forward to hearing your rendition of Popcorn is it going to be sample based or are you going to turn Paula into a synth producing beast

in video memory it has to store them in 2P mode to remember other player ice block positions.

The algorithm creates paths in a full screen in a pseudo random way (first maze is always the same if you don't let the demo roll), deletes 2x2 iceblocks when needed

no9 is going to handle that. He'll probably do a very good job as always with some superb music modules so sample based but I think he extracts the samples from the tunes / recreates them from waveform, well out of my league even if I used octamed extensively in the old days.

About Pengo music. I always think that Popcorn theme was original arcade music. But from readed comments on YT, it looks like Alternate version was original arcade music.

[ Show youtube player ]

I think that this game has 2 versions of music, perhaps one for Japan and second for USA arcade boards.

[jotd]

Alternate music comes with "pengo set 2" which is much harder than pengo set 1. If no9 has time, I may ask him to support this version too.

I thought Popcorn theme was original version too but got changed because of copyright infringement? Ahh the 70s and 80s when programmers were not lawyers and didn't know much about Intellectual Property infringement

@Jotd: The game is less than 16 colours or less? Has an Atari programmer reached out to do a ST port? It's 224 pixels long so OVERSCAN mode for NTSC users?

Is this game 100% blitter or are you using sprites as well?

I thought that too.

so many questions... that I can answer to


- game uses 16 simultaneous colors, and can switch color banks (ice pack title screen uses alternate tiles, palettes & sprites)
- No Atari programmer ever reached out for any game I ported, no. But someone reached out with Galaga 90 X68000 source code that was used to do the Falcon beta
- It's not 224 pixels long, but 288 so even PAL struggles.
- the game doesn't use the blitter at all. All sprites + cpu writes to display static blocks, "smart" algorithm to group objects with the same palette by sprite pairs (6 sprites, but colors aren't independent, fortunately in most cases 4 sprites share the same palette)

I think it's the game I've played the most after all. I love this game I never get tired playing it. Casual, but committing if you want to reach high levels (my best effort without cheating is level 13)

[gimbal]

Not enough games thank you for playing it. Such a simple gesture with such a big effect. You feel at home immediately.

[tarr]

Could it be possible to make an OCS 1MB version of Psychic 5?

[aeberbach]

Fast on/off switch? This is probably the same effect as the piezoelectric ignition spark applied to the coin slot plate?

[desiv]

Awesome!
This is another game I'm not great at, but was always fun.
(That's a LOT of games for me btw... ;-)

Also, there is a recent homebrew port for the Atari 7800 that is really impressive.

jotd...thank you so much for this. This is my favourite arcade game of all time and to have it on my Amiga is going to make me so happy.

Ahh Thanks for answering. So vertical Overscan for PAL mode.

Looking forward for the release

Being able to get up to level 13 seems like real good value for money.

The best value for money I ever played was Elevator Action Returns 2. I've never finished a SF2 or MK2 at the arcades, was worse when the machines had broken joysticks and you couldn't jump or block

Well, not really. In the early 80s when I was paying for the game I don't remember doing very well. But when the MAME version was available I trained hard.

I didn't play that one much. I played a lot of the first EA, would also be a good candidate for an amiga remake... MK was ok but MK2 was a scam!

Update on the project: could play all 16 levels with all intermissions working, fixed a lot of bugs and implemented a few sounds. No music yet. This is going better than I had imagined.

[jotd]

Another update (now that I figured out what was wrong with lagarith codec)

[ Show youtube player ]

Preview version will be zoned soon. It eats too much memory but runs on 2MB chip/fastmem at least. Will reduce requirements to A500/1MB in the end.

[TCD]

Looking forward to play the preview later

[jotd]

Made some progress with pack ice screen & fixed most colors & issues. Zoned a version.

Still needs a lot of memory but will be worked out later.

[zzbylu]

Great game!
