Good point... Can you remind me what the difference is?

I'm assuming they're basically the same, but referred to in different ways.
-The CPU that executes the instruction set.
-Files that require the instruction set. (But isn't the instruction set itself.)
-Etc.

Remember kids! Before you go on that interview, remember to wash your hands in teawater! *Coughs on hand* (Excuse me, I just coughed up a little teawater, so they're still clean!) You wouldn't want that hiring manager to be unimpressed.

May the force be with you!
Shoo! Why does it smell in here?
Maybe that's the wrong kind of force. *smirk*

the little v is a reference to a whole CPU architecture/serie. Like the X in a intel architecture number X000.
ARM7TDMI is one of the CPU's in the v4T set. Very old.
This is a good list:
https://en.wikipedia.org/wiki/List_of_ARM_microarchitectures

Oh and apparently, the CPU of the DS is even older than the GBA in comparison.
ARM7TDMI: 1998 - GBA release: 2001
ARM946E-S: 2000 - DS release: 2005.
Damn.

Thanks... Although, in the original post (previous page), I wasn't referring to it with the v, however, that is nice to know about.
I was just simply referring to it as ARM7/ARM9, because that's the way I've seen it labeled. Any of the more extreme specifics, I haven't looked into yet. (Don't really need to know it for hacking, I suppose... I think terminology has been one of my weaker points so far...)

Damn.
The GBA was released in Japan on March 21, 2001.

Interesting... However, that may sound reasonable....
-Cut costs by using an older system you were already testing before the new architecture...
-The GBA could have been made before release.../ Millions of GBAs could have been manufactured before "release"....
-And nobody can know when new bugs are introduced in new versions... (Of course, the GBA does have bug(s) anyway, but...)

There's a Python class that has people using an older version of Python instead of the newer one... so it can be thought similar to that as well.

And to an extend, that is not really bad. Especially in the CPU world there are to many different terms going around, often synonymous or way to detailed.

Yeah it is. Most console also use this principle. (PS3 excluded they had their own special CPU made, which turned out to be a very awkward thing, but getting a hella lot of topic here).

Update: I'm almost done with a very small assembly demo.

I agree...

WORD is probably one of the big ones... Some groups think it is 16-bit, others, 32-bit. - Really dislike how that terminology works...

Pfff yeah what nonsense that is.
Especially in x86. Every instruction is bound to a word size, but some can deviate. Sad

Fox: I must say... life can be complicated..... when you have question(s) (via email) ... and it seems like they sort of get ignored. :D ; Fun, (And sometimes, a person may respond, and completely not answer the question.... so like... 3-person conversation.) Hahahaha!!
January 15, 2018, 07:26:16 PM
Fox: (path) 1 text=(address) char=(address) free=(address) ; << Well, closer to this... but yeah... even if I do choose to have defaults in the code, I could still use this method for overrides.
January 15, 2018, 07:24:28 PM
Fox: So like (path) 0 text=(address) char=(address) len=(number) ; (path) 1 free=(address) ; Or something. But that's just a quick example.
January 15, 2018, 06:59:14 PM
Fox: Hopefully. I was wanting to make it so you could put in the addresses/etc. as one of the arguments in the path. Hm?
January 15, 2018, 03:37:07 PM
KyleRunner: Nice! I hope you'll add compatibility with others games (GS1, Mario Golf and Tennis) soon.
January 14, 2018, 11:40:09 PM
Fox: Okay. Posted (in Downloads section) an initial cutdown version for now, for my text compressor. Basically to separate the code from my Editor for anyone who wants to mess with it. It only supports GS2, because I still didn't add the addresses/etc. for the other games.
January 14, 2018, 05:01:00 PM
Fox: Okay! Going to need to think how I want it to work. Initial thoughts is maybe have a number of arguments in the filepath thing. And have a number of shortcuts (files) to be used as examples. Assuming there are no problems.
January 14, 2018, 10:38:24 AM
KyleRunner: Well... I'm used to editing text ina a text editor, so... yes! Thanks in advance!
January 13, 2018, 11:38:43 PM
Fox: (Text editor = Text Document like notepad.)
January 13, 2018, 11:38:21 PM
Fox: Would you prefer during the text editing in a text editor? (Like what gstoolkit lets you do?) I could probably make a separate tool or something to compress it.
January 13, 2018, 10:10:02 PM
KyleRunner: Ok. Once I finish my Lost Age translation, I'll try a Mario Golf one. Thanks. (But I'll need help).
January 13, 2018, 10:03:17 PM
Fox: If you want to make it "permanent" (part of a hack), then you'd edit code in the ROM that writes to this location of the IDs you'd want to change. (You can find these locations by using a breakpoint debugger like SDL-H or no$gba.)
January 13, 2018, 10:00:11 PM
Fox: Reload/switch = Recommended to be done through Debug mode/warp menu, ofcourse... since doors seem to appear as if they were disabled? ; 03001238:01 and B+Start to get to warp menu.
January 13, 2018, 09:55:39 PM
Fox: @Kyle Runner = It might be, but you'd have to use the correct addresses for Mario Golf, rather than for GS2 as I have it right now. ; @raijinken = Yes. 02000454 = ID of leader. (Change this and reload/switch room you are in, enjoy.)
January 13, 2018, 02:23:29 PM
raijinken: Hey guys, is it possible to somehow change the lead character on the map? Was wondering. I remember there was a cheat to use Jenna, but what if I wanted Isaac, or Piers?
January 13, 2018, 02:10:03 PM
KyleRunner: Hey, Fox *
January 13, 2018, 02:09:37 PM
KyleRunner: Hey, is your text editor compatible with Mario Golf (GBA)?
January 11, 2018, 08:33:13 PM
Fox: But if it isn't an oversight, I still can't imagine it being that useful.
January 11, 2018, 08:28:24 PM
Fox: part, ofcourse.
