This program rotates pixel art, giving fewer jagged edges than point sampling and less blurring than bilinear filtering. It's a free alternative to RotSprite, using a similar algorithm. It supports rotation at any angle, scaling the output image, and correcting for the odd pixel aspect ratios of second- through fourth-generation consoles. Requires Python 2.6 or 2.7 and Python Imaging Library.
Third- and fourth-generation game consoles (1984 to 1991) store their graphics as 8-by-8-pixel tiles. Most paint programs do not support the formats these consoles use. That's why there's 8TED. This program can edit tiles stored in the native formats of the NES, Game Boy, Super NES, Game Boy Advance, Sega Master System, Sega Genesis, and more. Use it to hack existing ROMs or to create graphics for your own ROMs.
The package also includes programs to create screen layouts for NES games, convert bitmaps to an NES CHR, remove duplicate tiles in an NES CHR, and pack data using run-length encoding.
In the Windows 95, 98, and Me days, it was possible to replace the image shown while the system was booting by replacing a file called logo.sys. This program would randomize the boot screen. Because it no longer applies to any currently supported version of Windows, this program is unsupported. It remains available for historical reasons.
Microsoft ClearType exploits the misalignment of colors in LCD display systems to draw anti-aliased text with better resolution than a perfectly aligned display would allow. (Read this page for details.) This program uses a similar sub-pixel antialiasing technique on arbitrary bitmap images in bmp, pcx, or tga format, or more if you download plug-ins and recompile the program. It supports command-line options to optimize for both RGB order displays (such as most laptops) and BGR order displays (Game Boy Advance; some iBooks).

All programs made available on this page are free software (also called open source software) unless otherwise specified.
Older game consoles (1984 to 1991) store their graphics as 8-by-8-pixel tiles. This command-line program converts .bmp files to the formats used by game consoles, the same formats supported by 8TED (below). It supports sprite sheet conversion at various cel sizes.
As of June 2012, certain falling block games are no longer available.
