G1M Format - E-Activities - Unknown Line Types

[cakeisalie5 Profile Website]

Hello,

so I'm making a little library that parses G[0-9]* files. I've added MCS and G1A support, and I'm adding E-Activities support, but while parsing, I've encountered some unknown line types:
- 0xc1
- 0x08
- 0x06

Here's the full log if you're curious:

Any idea what these lines could be?

[helder7]

Please upload the file "FlyingFish.g3e" somewhere, for I (or other person) check .

[cakeisalie5 Profile Website]

Oh yep, sorry! Here it is
Btw, I discovered strips today and my tests showed that these were strips IDs (except for 0xC1, which I don't know about).

(and it looks like some of the IDs of the strips)

EDIT: OMG, sub-e-activites are a thing ? Oo

[cakeisalie5 Profile Website]

So I've made some more tests with strips I did on my tweaked fx-9750GII-2. Here's the STRIPS.g2e.

Here's the log:

The e-act is the title, then "OUI." in text, then "99+5", then its result (104), then a "RUN" STRIP containing "NON", then a "NOTES" strip containing "Le saviez-vous ?".

This format is funny.
Have you explored all of the types and strips yet? What about the recursive form?

[helder7]

In EactMaker project we just explored Note strips.
According to my experience, strips inside strips is something that is not possible. This function does not seem to be implemented. I think this limitation is related to the way who the OS deal with strips.
The only "hidden feature" that I found was the use of locked colors in fx-CG calculators.

In the file "STRIPS.g2e":
The "calc mode", need the height and the width in pixels of the contained equation in the line. Calculate it is not trivial. If what you want to do is just parse it, this should be no problem.

Sorry for not answering straight away!

Strips inside the main strip is possible. I've parsed it like this, and it worked (even if there is pretty much only a header and the name):

Did you discover how the locked colors are aligned for pure text?
How are the calculation and the calculation stored (how can I parse it)?
What does "UI.main" mean for the last pure text field?
What about the other type, 0xc1?

Thanks in advance
