The LaserActive player detects whether either a CD or an LD has been inserted, and based on that, the mechanism of the drive physically adjusts itself to read the inserted medium (focal distance seems to be different, so the disk sits at a different height). The PAC doesn't have any control over th...

Fuck. Yeah. :D What I've done is to allow the LaserActive to start a MegaLD game, then as the game is booting, hijack the main M68000 processor and run my own code, which is in tern able to lock/reset the sub M68000, and read/write its program memory. The above data was obtained simply by dumping ou...

Some games use CD-DMA, which requires more than just BIOS interaction. It would seem to me that only games that came on cart that tried to use the CD would need to be able to handle the CDC directly... games like Pier Solar... of which there's only one - Pier Solar. Nope. Pier Solar uses the BIOS. I...

Yes, my immediate thought looking at the SMD is Jaguar CD. Is that it? I don't care to be the one to second-guess the Sega CD. But with a framebuffer and improved color depth, it would have been quite intriguing -- a whole different ballgame, even. It's a nice fantasy. That said, I kinda enjoy the s...

SOMEONE has to be tracking the hours, and if the employee does it and hits their boss with it, you can bet the boss will put in their own time clock, and/or fire said employee. You refer to this statement: Among other things, those regulations require employers to maintain detailed records of hours...

If you don't punch a time clock, you aren't being paid by the hour, you're a salaried employee and overtime doesn't apply to you. Period. Under the FLSA, an employer is not legally required to track the actual hours worked by exempt employees. For the reasons I mentioned earlier, game development e...

For month or for year? :) Think you can earn $24K per month?!? Sure... go ahead and dream big! (Just don't wake up -- you'll be very disappointed.) Certainly, it's a yearly salary. The $24K limit appears to be comfortably low in this industry. To put it in perspective, the average game dev's salary...

Re: The death march
Editors stole our dream, abused our passion to turn us into modern slaves. Slaves? No, not even close. Overtime only applies if you work by the hour. Salaried employees are paid by the JOB, not the hour. There is no such thing as overtime - if they can get the work done in 4 hours, they've got time...

If you help me find which one micro/nano-instruction you need all the 3 units working altogether it will be very helpful. Well, there are definitely more than one. In many cases, the ALU executes some value AND -1 in order latch the value while the AU does something like PC+2. It's all a matter of ...

I'm not sure you're referring to. I know that 68K uses two 16bit ALUs instead of 1 of 32bits. If you don't agree with sharing ALU with data and addresses: as I said earlier they don't overlap. To fetch only PC register is needed, no ALU operation occurs. If you want to say is that ALU and shift ope...

There are some things uncovered in the 4,325,121 for example the damn PC:=PC+1, I really don't know how to fit it in this design without adding and extra adder. That's exactly what you should be doing. Are you generalizing the execution unit into a single ALU? In FIG. 3, a simplified block diagram ...

If you're serious about it:
US Patent 4,307,445 - Microprogrammed control apparatus having a two-level control store for data processor
US Patent 4,325,121 - Two-level control store for microprogrammed data processor
I doubt you'll find anything more specific.

Do you have a disassembly of the SVP code? I've wanted to see what the SVP routines did, but could never get the IDA plugin to compile for linux. Here's a plain disassembly created with my own disassembler: vr-svp.asm (converted to something like normal SSP syntax; the old versions use my own style...

Oops, I lost track of the thread. Nicely done, Artemio! How could I set _HBL TascoDLX? I did find that bit of code at http://www.retrodev.com/segacdb.asm but it only had that and I couldn't find any info on it... Where can I read about that?

-There's a small paper label on top of the SVP with the words "SEGA SVP 160P" written on the top line, and the number "179" written below. Underneath the paper label, on the SVP chip itself, is the writing "SEGA160FS", with the writing "ES311" on the line below. I wouldn't bet that '160P' indicates...
