Great! Just wondered what happened with 1st and 2nd in the hi score table? ;-)
Keep up the good work

Outstanding again jotd, you're a port machine!

Looking great so far.

[nikosidis]

You are so fast

One of my all time fav.. games.

I'm sure it will be perfect. Looking forward to try it out.

Requirements: A500 1MB?

[Radertified]

1st and 2nd place on the high score table don't matter anymore.

We battle for 3rd place.

[jotd]

requirements A500 512k probably. 1MB if I can't do otherwise (the tune at the start is a long sample and takes a bit of memory at 22khz).

Didn't even notice that 1ST and 2ND were missing! was more concerned by making the scrolling work. That will be fixed of course.

technical info:

- game uses dual playfield with 16 colors, but some of the colors change between top and bottom of screen (else I don't have enough colors)
- I used the pngs provided by hajodick (who created them from actual game data, but didn't disclose how he did). I re-built the tiles from the images with a python script and extracted tiles & asm tables from that. As good as decoding original data (which I'm not taking the hassle to do)
- stars are done using sprites, taking low priority vs playfields
- game uses X-wise hardware scrolling.
- scenery tiles are updated without using the blitter. The tiles are 8 pixel wide. Blitter is used for ship and later for moving enemies.
- game uses dynamic palette changes (like the arcade)
- to rip the sounds, I hacked into the MAME debugger to turn off sound loop. That way I can rip the sounds without the background loop.

Nice JOB!

Looks fantastic, great work, one of my favourite early arcades!

I was thinking, maybe an option for copperlist background but probably wouldnt look great due to the aspect ratio.

Just a FYI but the new Amstrad CPC is very impressive also.

@Jotd: it's fantastic !

I have a suggestion for fire, the arcade uses 2 different buttons for normal fire and one for bomb. Probably you will use this combination, and it's perfect.
But if you can add an option to have both normal fire and bomb with one single button it will be highly appreciated, because it improves gameplay, at least for me.

Thanks for you attention.

Will do that because I want to support single buttons joysticks anyway.

Looks amazing! I think the ship is able to move too far towards the right of the screen for now?

Can't wait for a test version

[S. Campbell]

Scramble! YAAAAAASSSSSS!

[Fiery Phoenix]

Loved playing the recent C64 Scramble Infinity.

Can't beat a bit of Scramble action

[TjLaZer]

Excellent! Ports for C64/Atari 800 and now Amiga! ST next?

Nice port!

Its very similar to a game I used to play back in the day on my BBC Micro Rocket Raid.

I think you'll find that Rocket Raid is similar to Scramble.

Indeed, I 3d printed and painted a BBC Micro for a friend at Christmas and made him a special USB BBC Micro emulator with Rocket Raid on as he remember the game too and wanted to play it (a real Beeb was a little bit too much).

Another excellent looking port - you sir are a machine!

small update video, more sounds, collisions & ship explosion
