/g/ is fail

Name: Anonymous 2007-11-20 19:03

I was looking into modding my psp, and custom firmware's caught my attention. Now, I know building one from scratch is out of the question for a newb, but I wouldn't mind taking a gander and altering to some extent. I have some questions tho...

1) Wikipedia states the PSP(amongst various other consoles) uses a system based on the old RISC computers. Does this mean i can use mips assembly programming for RISC comps? Is that the language these firmware are written in, or...?

2) What hardware/software would i need to import/export the firmware from/to my PSP, and then read/edit? Can I use the handily built-in USB port, or do have to do some soldering/general arsing about?

3) Is there any resources or documents detailing these processes,Information found/discovered, or common hacks used?

I KNOW dark Alex had already made some, but I'd like to take a shot at it.....

tl;dr - how do i programmed PSP?

The PSP doesn't have an MMU, if I'm not mistaken, and I don't know whether the R4000 generally does.  So uClinux might be a good place to start.

On a similar note, how about a TI-83 calculator?

1. RISC != MIPS

Also, there's Lua and Python to work with, no need to deal with assembly unless you need more performance.

2. Yes, transfer executables to the GAME directory or something like that.

3. Get Dark Alex' firmaware, Google.

MIPS == RISC.
MIPS (originally an acronym for Microprocessor without Interlocked Pipeline Stages) is a RISC microprocessor architecture developed by MIPS Technologies. By the late 1990s it was estimated that one in three RISC chips produced were MIPS-based designs.

Jesus Christ, go take a mathematical logic class.

MIPS \subsetneq RISC.

MIPS = RISC \rightarrow (\forall a \in MIPS)(\exists b \in RISC)[a=b].

Proof of falsehood by example: The IBM-801 is a RISC processor. It is not a MIPS processor. The above statement is false.

Of course that's what i meant. That's like when you say a bus is a vehicle or a bike is a vehicle or a hovercraft is a vehicle. bike == vehicle as bike is a subset of vehicle. MIPS == RISC because it is an implementation of a RISC. Just like UltraSPARC is a RISC because it is another implementation of a RISC.

Jesus Christ, go take a mathematical logic class.

Let E be the set of even numbers:
E = {x ∈ ℕ: x ≡ 0 (mod 2)}

E ⊂ ℕ
∀a∈E (∃b∈ℕ (a = b))

Proof of falsehood by example:
3 ∈ ℕ
3 ∉ E

The above statement is false. lol illicit conversion

bike is a vehicle -> bike in vehicle
bike equals vehicle -> bike == vehicle

There is a world of difference between those two. You may intuitively know it, but by mixing the notation, you're effectively coming across as a fucking moran.

You noobs, is is the operator that compares references and cannot be overloaded, while == is the equality operator that's syntactic sugar for __eq__.

Name: Anonymous 2007-11-22 9:43

Wrong.

isinstance(bike, vehicle) returns True because it's a subset.
vehicle.__eq__(bike) returns False because it's not the same.

The fact that the syntax uses "is" to mean __eq__ means nothing.

Waitaminute, whats wrong with >>15?

>>9 claimed that MIPS = RISC. >>15 said that, for that to be true, every element in MIPS must be in RISC. >>15 then gave an example of a element in one not in the other, making the equality false...

You, on the other hand, attempted to prove that a set of even numbers was a subset of the naturals, then tried to prove it false by testing a number in the naturals not in the set of evens -- which is OK, but you assumed that E = N, not E subset N, and proved E != N.

>>15 is talking equalities, which says that each must be a subset of the other... you are not. By showing an element in one and not the other, it proves an equality does not exist.

Therefore, >>15 may be dumb, but is correct... >>18 makes an obvious fallacy and is a tool.

Of course, but I was comparing is to == just to piss you off and provoke some forced indentation of code comments on my forced introduction of Python to this thread.

Set theory is the branch of mathematical logic that studies sets, which are collections of objects. Although any type of object can be collected into a set, set theory is applied most often to objects that are relevant to mathematics. The language of set theory can be used in the definitions of nearly all mathematical objects.

Cantor's work initially polarized the mathematicians of his day. While Karl Weierstrass and Dedekind supported Cantor, Leopold Kronecker, now seen as a founder of mathematical constructivism, did not.
