ROM Layout
« on: September 14, 2010, 05:15:34 pm »
Hello,
What is the file structure of a ROM file? 0x0000-0x3FFF is Page 00, I know, and I think that 0x4000-0x7FFF is Page 01, and so on, but can someone give me a list of the page order?

Do you mean the .rom files on a computer? Or do you mean something else by including the addresses?

No, I got it figured out.  Thanks, though.

Could you post your results in case someone else has the same problem?

I thought you were just using Wabbit for the emulator?

Nope.  Integrated debugging is not supported by any current emulator, so I'm making my own.

Ah.  That was TI Dev, which is entirely different.  People tend to get those mixed up x.x

Oh ok. My mistake. I couldn't remember which it was. Just remember seeing it somewhere :P

Well good luck on development.

Yeah I think it has to do with the tiDE acronym being kinda close to TI Dev x.x. I myself got them mixed up before. So much that I moved the TI Developer thread in the tiDE forum once.

For the emu I assume it will be mostly for use with tiDE, right? Not necessarly a standalone emu?

The .rom file is just a raw binary file containing the contents of the Flash ROM.
The first 16KB of the file is page $00, the next 16KB page $01, and so on until either $1F, $3F, or $7F for 83+, 84+, and 83/84+SE respectively. In the same order, the resulting sizes are 512KB, 1MB, and 2MB.

Thanks calcdude.  As for the standalone questions, tiDE is just a frontend.  I'm writing an emulation library that can be used on any application.  I plan on porting it to the Zune, Windows Phone 7, etc.
