That looks awesome.

Colors into 16-level gray fits quite well.

I know some, actually, except for DS. For DS I know No$GBA but it doesn't work, it just break my windows install and I have to reformat my PC a few weeks later.

Desmume has already passed NO$GBA in many graphics bugs and is getting close to its speed. (play around with max frame skip to 1 or 2 and limit or not frame rate, it depends on the game)
Also it is better for gaming because of save games, save states, allow to play zipped games (NDS games are huge!) and overall configuration is easier to get used.
It can also film your games and print screens are easier than NO$GBA. ^^

Some say strange damages of NO$GBA on pc like problems with graphics card but on mine, hopefully there wasn't any problem that seems related to NO$GBA. I don't know any weirdness about Desmume.
PS: now you can even import No$gba savegames and others save formats. Other emulator is ideas but it doesn't seem a great emulator but some use it in certain games.

This brings me good memories.

GBC was hard to see outside with sun light.
About my GB pocket it was just when it is too dark but that is normal.

I am starting to comprehend a bit of C++ stuff just by some occasional code or documentation I see around...

Anyway what are the differences between the PC and calc versions?

ya math programs are very usefull because then you don't have to memorize the formulas you mearly have to remember what the program solves such as a sequence total(how much it adds up to) solver i created friday

I memorize almost all formulas because of the many times I use them.

What I found really cool is using lists in calculating stuff in statistics and sometimes probability with combinations.

I couldn't find a suitable offline unsquisher in ticalc.
The closer I found was this: http://www.ticalc.org/archives/files/fileinfo/144/14428.html.
Oncalc there are unsquishers but doesn't serve the original purpose.

Note: unsquisher == hex disassembler, I think

For online TI files editor/reader I also know these:

 The HTML front end in black and white style is done. Now the real PHP will begin.

Thanks for the tips.

My difficulty now is the PHP. I am too green in it... I only have a small idea on how to do.

EDIT: I have been searching the right PHP functions.
I am thinking in file_get_contents() function to get the file content.
Then I just need to use unpack() function to get the readable hexadecimal.

This really seems that will work. I will add the same options as ticirrus.
