Retrieving System Generation?

[Kittsune]

Simple question: Is there a way to retrieve the system type? (e.g. Phat, lite, DSi, ect)

[vuurrobin]

programs usally shouldn't need to know on what device they are running on.

why do you need this?

it is helpful to know if you are in DSi mode as you have access to more memory and a faster processor. a quick test would be to allocate 4 MB of memory. if it works you are in DSi mode. you can currently also use the following code:

Code: Select all

extern bool __dsimode; 

I am not sure if it is a supported path, so use it at your own risk. if __dsimode is true then you are in DSi mode.

my homebrew sandbox engine ds-dsi detects dsimode.

This question comes up often enough that it's probably worth implementing a libnds function to obtain the system type. Patches are encouraged, pointers to libraries and/or random code that isn't supplied and maintained by devkitPro make life awkward for everyone.
