http://www.coranac.com my own little world Sun, 30 Nov 2008 17:59:26 +0000 http://backend.userland.com/rss092 en Apparently, the GRF format didn't quite follow the official RIFF specs, so I had to fix it (thanks for pointing it out, Daniel). While I was at it, I also changed the names of the meta-tile arrays if a meta-map was asked for. In stead of the -Map affix, it ... http://www.coranac.com/2008/11/30/grit-082-usenti-1710/ I found this little game yesterday: Light-bot. You control a bot with a few commands to light up evry blue tile in the level; kinda like LOGO or Lego Mindstorms. At 12 levels it's a nice little activity. http://www.coranac.com/2008/09/22/little-programming-game/ The state of register names for NDS homebrew is a bit of a mess. First, there are the GBATek names. Since GBATek is considered the source of GBA/NDS information, it would make sense to adhere to those names pretty closely. But, of course, that's not how actually is in the ... http://www.coranac.com/2008/09/11/nds-register-overview/ I think I mentioned this before, but we have this Book fair thing over here. These are generally wonderful in that the admission is free, things are usually pretty damn cheap compared to regular stores and even teh internets, and (very unlike most stores in this country *grumble*) there's a ... http://www.coranac.com/2008/09/10/hurray-for-bookies/ Tonclib is coded mostly in C. The reason for this was twofold. First, I still have it in my head that C is lower level than C++, and that the former would compile to faster code; and faster is good. Second, it's easier for C++ to call C than the ... http://www.coranac.com/2008/09/03/to-c-or-not-to-c/ <ramble> I think too much. Or so people keep telling me. And they may have a point. Anyway, so I'm working on this assembly version of toncset for, well, just because I guess. A fill routine has 3 parts: a head, a main run and a tail. The main part fills 32-bit chunks ... http://www.coranac.com/2008/08/21/define-overthinking/ The files have need downloadable for a while now as a preview, but I finally put the text up on the main site as well so I guess that makes it official. Tonc is now at version 1.4. As mentioned before, the main new thing is TTE, a system for ... http://www.coranac.com/2008/08/19/tonc-14-official-release/ “Matrices from a geometry perspective” is now out. Vector and matrix math is used heavily in computer graphics because it involved geometry and coordinate transformations. While this is widely known, I've seen many people struggle with the basic concepts of how it's supposed to work. this is especially true in ... http://www.coranac.com/2008/06/25/matrices-for-geometry/ I've added two new routines to the bit-trick page: 1→4 bit-unpack with reverse and bit reversals. This last one is elegant … except for one bit of C tomfoolery that is required to get GCC to produce the right ARM code. I hope to discuss this in more detail later. I've ... http://www.coranac.com/2008/05/30/fiddle-to-the-bittle/ I'm close to releasing the latest (and probably last; this really has gone on long enough) version of Tonc. As a preview, I'm releasing the PDF a little early in the hope that someone may take a look and offer some feedback before the official release (aw, c'mon, it's only ... http://www.coranac.com/2008/05/26/tonc-14-preview/
