Re: powervr2 limits

So while the DC has less memory available for a cache
I can't proof my point with a slides or some other info but I recall that I've seen a diagram that shows that bigger cache sizes doesn't necessarily mean boost up.

Re: powervr2 limits

Well, Dreamcast system has some specific hardware features, yielding which, better performance may be achieved at some stages of the pipeline (for example, Dreamcast has the Tile Accelerator, which PS2 lacks, taking advantage of this concrete feature may gain some good results, or, for example, adva...

Re: powervr2 limits

Can the pvr emulate psp games ? If we want to keep answer simple, no, it's not. Pvr2 alone can not emulate psp games, it requires all hardware to cooperate in a maximum efficient manner. Also, I even doubt that DC will be able to emulate PSP games at fullspeed (considering PSP is more "powerful" th...

Why are we use "elf" as intermediate format for bin files?

Let's look into some random example from KOS:
$(KOS_CC) $(KOS_CFLAGS) $(KOS_LDFLAGS) -o dreameye_test.elf $(KOS_START) \$(KOS_LIBS)
(from dreameye makefile)
If we change linker output format to .EXE, wouldn't we being able to make .BIN from them?

How does ADD/SUB/arithmetic instructions treat arguments?

For example, let's say we want to add the contents of two registers on Sh4. We add R0 and R1 (by value). R0 contents is 0xFF. R1 contents is 0xAA. Does ADD/SUB instruction treat values in registers as signed or as unsigned values? For example, when adding those both registers, will R0 contents will ...

Re: running compiled programs?

I would highly recommend against using of emulators, especially such one as nullDC. It is bad written, untested, unreliable piece of software on which you really shouldn't rely when testing your programs.
Better run your programs on real hardware.
Or test on others emulators, like makaron or demul.

Re: How is it in America now?

Every level of schooling in America, from preschool to the end of college, is completely broken in our country. We invest so little in education that it's a miracle we are a global competitor at all. Lol. I always thought (and still think) that America is a leader in educational products. Many of m...

Does it still stay sold to insurance companies?
How difficult it is to receive a medical help?

You said that you want to study for a psychologist.
How much does it cost to be educated in America?
Does education paid at all or it's free or at least state will cover some expenses?
Is there some government programs that give material\money support to students?
