Indie Retro News: Gyruss - Exciting news as JOTD is working on another Arcade to Amiga port!

JOTD has actually earned a optimistic repute within the Amiga scene, as he is among the few builders prepared to go the additional mile, to transform/port over some fairly effective Arcade to Amiga titles. Moon Patrol, Donkey Kong, Tremendous Bagman, Galaxian500 and Tremendous Xevious are simply a few of the ones because the spotlight on this web site. Effectively it does not look something goes to cease this powerhouse of a developer from creating Arcade to Amiga conversions any time quickly. As he has not too long ago introduced he’s now engaged on Konami’s good shooter of ‘GYRUSS’. A sport that JOTD says is hopefully going to get it working properly on the Amiga 500 and above.

And whereas there’s little or no to speak about simply but, here is what JOTD says concerning the challenge, which remains to be in a really early stage of improvement ( no sound in video ). “That is fairly advanced to port because the arcade machine makes use of 2 processors and no supply is on the market”.

– the Z80 is used as essential cpu do to most issues BUT…
– the m6809 is used to challenge/repair/recompute the coordinates, which is that’s offering the round impact in Gyruss. With out it, the sprite placement is totally off. This 6809 to 68000 conversion can also be the primary one performed with my 6809to68000 converter.
Thankfully the code is small. Do not ask me how the coordinate conversion works. I suppose they’re utilizing stuff like cosine/sine tables in ROM, and there is some multiplying concerned too. Undecided concerning the FPS on an actual machine, will most likely want 25 FPS solely however that is cool.

And that is all there’s to say to this point, however watch this house for extra!
