Gyruss - Exciting news as JOTD is working on another Arcade to Amiga port! [WIP Download]

JOTD has certainly earned a positive reputation in the Amiga scene, as he is one of the few developers willing to go the extra mile, to convert/port over some pretty fine Arcade to Amiga titles. Moon Patrol, Donkey Kong, Super Bagman, Galaxian500 and Super Xevious are just some of the ones as the highlight on this website. Well it doesn't look anything is going to stop this powerhouse of a developer from creating Arcade to Amiga conversions any time soon. As he has recently announced he is now working on Konami's brilliant shooter of 'GYRUSS'. A game that JOTD says is hopefully going to get it working nicely on the Amiga 500 and above.

And while there's very little to talk about just yet, here's what JOTD says about the project, which is still in a very early stage of development. "This is pretty complex to port as the arcade machine uses 2 processors and no source is available".

• - the Z80 is used as main cpu do to most things BUT...
• - the m6809 is used to project/fix/recompute the coordinates, which is that is providing the circular effect in Gyruss. Without it, the sprite placement is completely off. This 6809 to 68000 conversion is also the first one done with my 6809to68000 converter. 
• Fortunately the code is small. Don't ask me how the coordinate conversion works. I suppose they're using stuff like cosine/sine tables in ROM, and there's some multiplying involved too. Not sure about the FPS on a real machine, will probably need 25 FPS only but that's cool.

And that's all there is to say so far, but watch this space for more!

UPDATE : As promised we've got some more news about this upcoming Arcade to Amiga port. And here's what JOTD has recently said about the latest demo. "No music yet. But using audio mixer, what you're listening to is only 1 audio channel. This is what it would look like on a fast amiga though. The current version available below has some speed issues on lowly machines".
