Does anyone know where the font tables reside in memory? I am going to write my own text display routine and don't want to use romcalls to get the sprites.

They don't reside in RAM, they reside in ROM, and they change address and page in each TI-OS version. Doors CS contains a several-KB replica of the font table for this reason, for instance. 
Several KB? (!) Okay, so I HAVE to use bcall(_Load_SFont) or bcall(_LoadPattern) to get the sprites?

Yup, unless you want at worst [256*5 + loading routine + exceptions] bytes of table, or at best some optimized version of that.
Yeah, well I don't. I already am struggling with program size if I want to cram all those features in. I'll use a romcall. Thanks for the info!

My pleasure. How many characters do you need, though? If you only need letters, numbers, and a few other characters, you could omit all the characters that you don't need.
I only need the characters for the numbers 0 to 9, but I don't think it's worth it to even create my own sprites for those. It would've been handy if I could acces the TI-OS's sprites directly, but I don't mind the romcall overhead I guess.

Oh, it's only zero through nine? Then just use sprites! Or make your own cool font! Cf. Invalid Tangram for an example of that principle. Register to Join the Conversation
