If we're talking like Real numbers, Euler's Constant (the riemann zeta function evaluated at 3). If in general, the maximal element of the ordinal numbers.

Posted on 06-11-05 11:43 AM, in SPC bootstrap rom

Link

I was looking through the snes9x source code when I happened upon the rom that the SPC boots up with. I decided to try to convert it to assembly code, in spite never having looked at SPC700 asm before O_o. ouch.... here goes


//added by MONapkins
/* above rom reads in spc opcodes:

	MOV		X, #$EF
	MOV		SP, X  // the stack is at $EF

LOOPBACK:
		
	MOV		A, #$00 
	MOV		(X), A // zero out $01 through $EF
	DEC		X

	BNE		#$FC (LOOPBACK)

	MOV		$F4, #$AA // #$BBAA is the classic value you see on the 65816
	MOV		$F5, #$BB // side of things, indicating the SPC is "ready"

LOOPBACK2:

	CMP		$F4, #$CC  // another value seen on the 65816 side, when preparing to send data. As I recall, this value is fed from the 65816 side through the $F4 port.

	BNE		#$FB (LOOPBACK2) // Hence, until we receive that message, we do nothing.

	BRA		#$19 (BRANCH2)

LOOPBACK3:

	MOV		Y, $F4 // put that lower byte in Y

	BNE		$FC (LOOPBACK3) // maybe an internal process insures $F4 will drop down to zero. Otherwise this is an infinite loop.

LOOPBACK4:

	CMP		Y, $F4

	BNE		#$0B (BRANCH1)

	MOVZ	A, $F5
	MOV		$F4, Y
	MOV		[$00+Y], A
	INC		Y

	BNE		#$F3 (LOOPBACK4)

	INCZ	$01 // again, you got me on the specification here.

BRANCH1:

	BPL		#$EF (LOOPBACK4)

	CMP		Y, $F4

	BPL		#$EB (LOOPBACK4)

BRANCH2:

	MOVW	YA, $F6 // move a word of data received from the 65816 ($2142-3)
	MOVW	$00, YA // move it to $00-$01
	MOVW	YA, $F4 // check the word on the other port.
	MOVZ	$F4, A // it's called MOV with zero extended, but I'm not sure what exactly that means. Maybe it erases the upper byte, i.e. $F5
	MOV		A, Y // 
	MOV		X, A // chain along the upper byte to X
	
	BNE		#$DB (LOOPBACK3) // if it wasn't 0, loop back and do some stuff

	JMP		[$0000+X]

	DI      // no fricken clue...

	STOP
*/


for posterity I will also provide the data in the globals.cpp file

uint8 APUROM [64] =
{
    0xCD,0xEF,0xBD,0xE8,0x00,0xC6,0x1D,0xD0,0xFC,0x8F,0xAA,0xF4,0x8F,0xBB,0xF5,0x78,
	0xCC,0xF4,0xD0,0xFB,0x2F,0x19,0xEB,0xF4,0xD0,0xFC,0x7E,0xF4,0xD0,0x0B,0xE4,0xF5,
	0xCB,0xF4,0xD7,0x00,0xFC,0xD0,0xF3,0xAB,0x01,0x10,0xEF,0x7E,0xF4,0x10,0xEB,0xBA,
	0xF6,0xDA,0x00,0xBA,0xF4,0xC4,0xF4,0xDD,0x5D,0xD0,0xDB,0x1F,0x00,0x00,0xC0,0xFF
};

So anyways, just out of curiosity, anybody know what MOVZ and DI are for? I've read some docs on MOVZ, but it's a little unclear. And DI is on the SPC700 opcode list, but I can't figure out what it does from any source I've seen.

I recently acquired a game doctor SF7, and I've seen plenty of internet info about a program to transfer data from a computer to the game doctor via parallel port. The program in question is TSF3.exe, yet I have been unable to find a location to download it. Does anybody here have it, or know someone who might?

Sweet, I had heard of ucon64, but didn't know it has the capabilities of the other program. I thought it was just for file conversion.

You should blame nintendo. Notice that the large green block patterns also seem to violate perspective. Most objects in the game are at a slant towards the north wall, whereas the dungeon walls are designed to give a sense of vanishing point. Doest it makes sense? no. But I think if they designed the south walls they way they should, it would look even weirder. Sort of like Ultima but not as bad.

Posted on 06-12-05 10:18 AM, in 65816 code problem.

Link

I assume the GIF has been converted to a proper format, and he's just trying to get an intro to work. As for the reason it doesn't work, it's possible the NMI routine for the game, or some other code, clears those registers before bleempan's code gets there. Look for other reads of $4218-9 and see if they're buffered in other memory locations. Try reading those instead. Make sure you interpret the data correctly though. I'd have to review some technical docs before being certain though.

What exactly do you mean? Tthough if somewhat catch your drift, the answer is yes. But you'd need to modify a certain module I have information on.

Posted on 06-13-05 06:16 AM, in Having trouble with computer powering up

Link

In the past month I've had trouble getting my system to powerup correctly. At first, it might take two tries on my power switch to get the BIOS information to appear on the screen. Then later in the month it was taking 4-5 tries. Now it's taking forever, maybe 20-30 tries to get started up. I've tried all kinds of different techniques, such as hitting the button multiple times, holding it, toggling my off/on (the one on the power supply) switch before, but nothing seems to help in a particular or consistent way.

-When the problem exists, I hit the power switch, and nothing appears on screen. My monitor doesn't even detect input, nor does my keyboard.
-When the problem finally goes away, the computer starts up, I see the system configurations like anybody does during bootup, and Windows 98 starts up just fine.
-I assume this is a hardware issue rather than software, and it seems to be mechanical rather than a matter of configuration, though I could be mistaken.
-If I restart the computer from windows, it boots up just fine
-If I turn off the computer via shutdown, or the power button, I have to jump through hoops to get it started again, as above.
-The computer itself while actually booted up properly, runs fine, maybe with a few exceptions. Every 5-10 hours or so of usage, it will slow down to a complete stop for about 6 seconds, and I can hear some sort of mechanical "stalling", though it's not very loud at all. Barely audible, you have to listen for it. This also usually happens after about 10 minutes after startup.

My guess is that something is worn out on the motherboard, and needs fixing, or the MB needs replacing... but I would appreciate anybody's insight in this mater.

Posted on 06-13-05 03:29 PM, in The World Affairs Constitution

Link

I was just thinking, though this may not be entirely relevant to the constitution per se, it would be cool to establish a profile for each person's political persona. The information submitted should be factual. This way, we have a reference if someone decides to argue via devil's advocate, and take a stance conflicting or different from their true stance. The format could be something like the following:

Views on Abortion:

Pro: I support abortion as long as there is significant risk to the mother in giving birth. I feel that sacrificing a person capable of producing additional life for a single child is a long term net loss, and I believe allowing someone to die needlessly is just as bad if not worse than the taking of a life. I also support the abortions for women who were raped, since I think it has the potential to be a constant emotional reminder of the traumatic rape event. Other special cases I may have forgotten to mention.

Con: Against unnecessary abortions at any stage. An embryo is an embryo, why disciminate based on the age of the embryo? agism? Sounds ridiculous I know. In this case it would be a net loss of life, with no justification.

Death Penalty/Execution:

Pro: I think it is a waste of money to keep dangerous criminals housed at the cost of the state. Economically, if there was an efficient way of killing the most dangerous criminals, I'd be all for it. I don't even like the idea of life in prison. If someone is really that unfit for society, why keep them alive? I don't care about the method used, b/c I don't think there is a humane way to kill someone. I voted for hanging in ||bass' thread, since it has high visibility if made public, it seems cheap, and is definitely not a pleasant thought for someone thinking about committing a capital offense.

Con: But there is the issue of whether innocents may be convicted and killed. The moral issue of whether we have the right to take anyone's life. Perhaps the person who committed the crime was acting at the behest of someone more dangerous. Many criminals rehabilitate and allegedly find God on death row, but it'd be a scary experiment to pardon them and send them back to the streets.

etc. etc.

Controversial Issue\Stance:

Pro: arguments, if any, in support of the practice, stance, etc..

Con: arguments to the contrary

(do not debate my views in this thread, for obvious reasons, though the above view is a roughly accurate sketch of my views on two subjects.)

What does anyone think of this idea, and do you have any suggestions for possible ways to implement a profile better?

I've thought about it on occasion, though it's something you figure out, nobody just comes out and says it.

In spite of that, this thread smartass, b/c no one ever refers to A/C for heating. They say turn the heat on. And in the summer they say turn th A/C on.
