Well.. I heard that's not the real pain in the butt about the Jaguar. I heard that it has REALLY bad framebuffer bugs that makes it much more challenging to program than it should be. There's a blog that covers the bugs with the jump command in particular. Very odd quirks that should have been worked out before the final release. Anywho, that's one reason I'm working with the 32X - no real bugs to speak of... in fact, most of the warnings in the developer docs all deal with developer hardware, not the shipping hardware, so I can do things for homebrew that developers were warned against. ;D

The 32X is way better than Jaguar. But developers complained about too many CPU's on that one too. Just think. Master SH2 Slave SH2 MD 68000 MD Z80 That's 4 CPU's!

It seems like a lot, but it's really quite simple when you break it down. Look at Wolf32X as an example: Z80 - ignored 68000 - runs a simple loop in RAM that reads the controllers and stores the values to communication registers for the 32X, and can read/write sram when asked to. Slave SH2 - runs a simple loop in cache adding the sound effects together to play through the PWM. Master SH2 - runs the game code. Probably most 32X games are similar, with maybe the Z80, but more probably the 68000, also playing MUSIC.

BUT BUT BUT You're forgetting the SegaCD 32X!
That's another 68K to the count.
When having a bunch of CPUs, using only one processor is lame. What about a killer 3D engine, or some advanced AI? There were some Seta CPUs used on a couple of Japanese SNES board games only for AI - that could be a interesting heavy use for those spare CPUs...
Back to the Jaguar, what about the CD drive? Does it add more memory/CPU, or it's just another CD adaptoid?

The Jaguar CD only adds storage, nothing more.
And not using the full processing-power of a system isn't inherently lame .. just use whatever your game needs.

Does it add more memory/CPU, or it's just another CD adaptoid? Yes, but to my knowledge you don't NEED to use everything and in the case that jlf65 spoke about it seems to make sence. BTW, I think he's only using one SH2 processor leaving the other one free. The thing about the Jaguar that makes it different than a system like the 32x is that there's at least information about the CPU's used for processing/video. That and the Mega Drive/32x/SegaCD are all separate systems.. So you can choose to be as complex as you want and you'll always information regarding the video/m68000/z80/and SH2. Tom and Jerry (The Object Proc and the Sound Proc) have little to no documentation out there for them. In fact, the devkits that were sent to developers were very much incomplete, buggy, and poorly documented. This is one of the big reasons other than the "jump" bug that most games for the Jag didn't look much better than the Mega Drive or the SNES. Many developers saw the 68000 and preferred to program for that rather than working with the Object proc and the Blitter. The good reason for having the CDRom is that there are homebrew devvers that could use "Protector SE" or "Battlesphere" to bypass the copyright protection and thus do development on the Jaguar. It doesn't add anything except space, the games for it are horrid and ugly. It's also not very durable and in most cases doesn't last that long.

It looks like a toilet seat too...
The Atari Commode. If you lift up the top while the CD's spinning, it may spin the right way too! Almost as if it's flushing the krap some idiot at Atari approved to be sold right into your Jaguar... lol

Has anyone cracked the "copyright protection" on Jaguar ROMs? I'm curious about that. Yes, throwing trojans at CD games are cool and such, but... what about a plain "native" ROM?

Do you mean to be able to create Jaguar games without Atari's consent for Cartridge portion?
I think so... I know that Battlesphere came out in 2005 and Protector came out after 2000. Meaning that I think that they cracked it, but then again It's been a long time since I've looked at Jaguar stuff.
