Fblit:
http://aminet.net/package/util/boot/fblitFtext:
http://aminet.net/package/util/boot/FTextFblit will replace OS blitter routines with CPU routines (faster with accelerators such as Apollo 1240) and Ftext will use Fblit to render text faster (good for editing and text viewing). The most useful part is that things such as Workbench icons can now be stored in fastmem, and this can save a lot of chipmem.
Just two things:
1) When using NewIcons, make sure to turn it's RTG option ON. Normally this won't work unless you have a graphics card, but with Fblit it does, and icons will be stored in fastmem.
2) With Fblit active, it's possible that changing the Workbench screen mode will result in a garbled display. This is the case for me, and while generally not an issue, be sure to keep it in mind.
