NEW GAME for 68k based Macs - VergeWorld: Icarus


Recommended Posts

That's insanely incredible! 8-o You've really got something in the making here!

 

I'll happily buy a copy when it's released! :D

 

Do you have any plans on recording Programming sessions? (I love watching/learning the process of coding for these old machines.)

That’s awesome.  Would be interested to know your approach.  My first reaction was “there’s no way to do full-screen blitting fast enough on a 68k Mac” but either (1) I’m wrong (but I don’t think I’m wrong) or (2) you are only double-buffering the area around the ship, and the rest of the background is being drawn direct to screen with hidden surface elimination, which is pretty clever.

 

I’m not sure how much of a perf boost you will get moving from C to asm, though, depending on where the code is slow and assuming you’ve already done all the obvious things like loop unrolling, which I’m sure you have.  (And of course, no color Macs had a 68000 anyway.)

Currently we only have Amiga and Atari versions, I have just bought Macintosh Performa 475 and will start porting like next month. We don't use any custom chips so I assume that porting is doable. 

We are using 2 environments right now, one is Cygwin and the other is Ubuntu on Docker

Your demo looks very promising. Some thoughts: A monochrome variant for the original 68000 is a completely different beast than colour games for the later models. However considering the original Flight Sim ran on an Apple II a game like yours is surely doable on a 68000.

The demo seems to require only 16 colours - on a Mac freely picked out of a 24bit palette. This helps with the original LC's slower system bus.

Your screen size seems also quite moderate. It may fit on the original monochrome's 512x342 pixels, and the popular Macintosh 12" RGB display (512 or 560 x 384).

For me the flight scene looks so attractive, I would want to see it embedded in a full game story.
