JOTD has definitely earned a optimistic fame within the Amiga scene, as he is likely one of the few builders prepared to go the additional mile, to transform/port over some fairly nice Arcade to Amiga titles. Moon Patrol, Donkey Kong, Tremendous Bagman, Galaxian500 and Tremendous Xevious are simply among the ones because the spotlight on this web site. Nicely 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 lately introduced he’s now engaged on Konami’s sensible 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 mission, which continues to be in a really early stage of improvement. “That is fairly complicated to port because the arcade machine makes use of 2 processors and no supply is out there”.
- – the Z80 is used as principal cpu do to most issues BUT…
- – the m6809 is used to mission/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 achieved 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 may be to say to this point, however watch this house for extra!
UPDATE : As promised we have some extra information about this upcoming Arcade to Amiga port. And here is what JOTD has lately stated concerning the newest video above. “No music but. However utilizing audio mixer, what you are listening to is just one audio channel. That is what it could seem like on a quick amiga although. The present model obtainable under has lots of pace points on lowly machines”.
