    Hi.
    I'm getting the same. Tried to post a new thread yesterday and got the message that it was awaiting approval (actually missed it the first time and thought I did something wrong, so may have a...

    Didn't the 3DO have this capability too? I recall the 3DO patents included one for per-line CLUT manipulation. Which wouldn't be surprising really as the 3DO was designed by ex-Amiga designers.

    Did many 32X games use both SH2 CPUs?

    As title, of the 32X titles released, does anyone know how effectively they use both SH2 processors? The 32X didn't really get much further than first generation titles, and I'm curious as to how...

    CPU comparisons (ARM, SH2, R3000A, J-RISC)...?

    For the developers on this forum who have programmed multiple consoles, how do the various CPUs compare? What are the pros and cons of the different processors you've used? I'm specifically thinking...

    Thanks Chilly Willy.

    It's useful to get a perspective from someone who knows both platforms well! I've read the SDK documentation about the maths instructions, but don't have the background to...

    Can we talk about the 3DO?

    I've seen posts that state how much more powerful the Jaguar was than the 3DO (because it had 2x26Mhz RISC processors, 13Mhz 68000, 64bit Blitter and 64bit Object...

    Slipstream? Can't remember the name of the company that was using it, but think it was three letters long starting with "M"?

    Thanks Crazyace.

    I've read through the VDP1 manual that describes the various pixel/colour formats and also the VDP2 guide and think I have it, but would appreciate any corrections or...

    Please forgive my ignorance here, but if the VDP1 framebuffer output is seen by VDP2 as just pixels and not sprites, how could it apply per-sprite priority? How would it be able to work out what...

    Thanks Crazyace.

    I've had a read of those chapters in the VDP2 guide, but to be honest, most of it is beyond me. This leads me to ask a couple of other questions:

    What exactly does per pixel...

    The Y-Board could do that, but I've not seen anything on System 32 that appears to do what is effectively post-processing frame buffer rotation. It would be odd that Sega would have designed their...

    System32 and ST-V (Saturn)

    I'm a bit confused by this as I've seen bi-axial rotation quoted in many sources regarding the ASIC as if it's something special. On the SNES...

    Yes. When I used the work "distorted" I was meaning the scaled/rotated/warped object.

    If I'm understanding this correctly, the ASIC performs the line by line rendering, writing this output to a...

    Thanks for the insightful comments!

    So am I right in thinking the ASIC is essentially similar to a Blitter in that it takes a source, performs some logical operation on it and then writes to a...

    MegaCD ASIC questions

    Hi

    I'm interested in finding out more about the SegaCD/MegaCD ASIC and what it's capable of doing. The Youtube video demonstrating the scaling and rotation capabilities is very impressive, but...
