Sweet16 2.0 development is chugging along. It has a number of nice improvements, in particular its totally rewritten graphics code that uses OpenGL to reduce load on the processor. This improves performance noticeably on PowerPC systems, less so on Intel.

You can also now choose whether the window should be displayed in 4:3 or 16:10 aspect ratio. Historically, Apple IIgs emulators have used 16:10, stretching the GS display vertically to 400 pixels tall. However, this creates an incorrect 16:10 aspect ratio.

That's actually good enough for ordinary use.

However, Sweet16 2.0 offers the option to switch to a 4:3 aspect ratio mode. This mode, while slightly fuzzy compared to the 16:10 mode, provides a more accurately scaled representation of the IIgs display, which can be handy for page layout and graphic design tasks.

Additionally, you can now resize the Sweet16 video window to any size you want, and the GS display will stretch to that size. While the display obviously looks best at its normal 640x400 or 640x480 size, you can make it whatever size fits your needs best.

Sweet16 2.0 also offers full screen support, a much-improved event management system, and a few other interesting new features and improvements.

I'm not sure at this point when it'll be done. I've got some work left to do on it. However, I'm tentatively planning a public beta version sometime in the next few weeks. The rewritten graphics and event management code could use some more strenuous testing than the regular test team has time to give it. There are almost guaranteed to be quirks in that build when I do release it, but it should help me nail them down and fix them.

I'll post more information as the test date approaches.
